I appreciate how you made achieving this goal simple and clear. Out of all the search results I reviewed on this subject the information is the only one that has value. Thanks

I learn something from more than 90% of what you send me in your newsletters. My wife and myself are 70yrs old and we aren’t very computer literate. We both have MacBook Air laptops. They are new and running macOS Catalina 10.15.7 We are reluctant to upgrade to macOS Big Sur. I’m collecting everything I can find that you print about Big Sur. Once we’re comfortable, I think we may try it. I’m writing to thank you for what you do for us and you ask for nothing. ThankYou! ~Peter~

How to View the Source Code of a Webpage in Safari on Mac

Behind every beautiful webpage is a complex code called source code that serves the design and the functionality of that webpage to its users. Sometimes you may get curious and would like to see exactly what code builds a webpage. Viewing the source code of a webpage is possible in almost all web browsers, and the same applies to Safari for Mac.

Safari for Mac does allow you to view the source code of a webpage; however, it does not work like Chrome or Firefox. To view the source of a page in Safari you need to first unlock a hidden menu in the browser.

Here’s how to enable that menu and then see the source of a webpage using multiple ways.

View the Source Code of a Webpage in Safari on Mac

1. Launch Safari on your Mac.

2. When Safari launches, click on the “Safari” menu on the top followed by “Preferences…”

3. When the Preferences panel opens, click on the tab that says “Advanced”. It should be the last one in the menu on the top.

4. Inside the Advanced tab you should see an option that says “Show Develop menu in menu bar.”

Checkmark the box for the option, and the menu should instantly be added to the menu bar in the browser.

The Develop menu is now unlocked in Safari on your Mac. Here’s how you can use various options it gives you to access the source code of a webpage.

1. Using the Develop Menu

In the menu bar of Safari, you should now see a new option called “Develop” that has just been unlocked. To view the source of a page, click on the “Develop” menu and then choose “Show Page Source.”

Safari should instantly show you the full source code of the webpage.

2. Using a Keyboard Shortcut

If you plan to access the source code of a number of webpages, you may want to use a keyboard shortcut as it will be much faster than clicking an option in the menu bar and selecting another option.

While a webpage is open in Safari, press the “Option + Command + U” key combination, and Safari should let you see the source code of the webpage.

3. Using the Right-Click Menu

If Safari is your primary browser, and you happen to be someone who is interested in viewing the codes behind various webpages, the guide above should help you do that without requiring you to leave your favorite browser.

How to view the HTML source code of a web page on Mac, iPad, and iPhone

Do you want to see what’s under the hood of web pages you visit? Check out how to view a page’s source code on Mac, iPad, and iPhone.

View source code of a web page in Safari

Whether you dabble in small-time web development or you just have the general interest of digging around in code to see how things work, there may be times when you want to see the HTML source code behind a specific web page.

It’s possible to do this from Safari (or other browsers) on your Mac, and for iPhone or iPad, you will have to use dedicated third-party apps.

View the source code of a website

Here are the steps for macOS and iOS.

The first step to being able to see the HTML code of a site is to enable Develop mode , a mode that Apple hides by default as the company assumes only developers would want to tinker with these options.

Enable Develop mode in Safari:

1) Open Safari and click Safari > Settings or Preferences from the top menu bar.

2) Go to the Advanced tab.

3) At the bottom, check the box that says Show features for web developers or Show Develop menu in menu bar .

Enable 'Show features for web developers' in Safari Advanced settings

In the menu bar, you will now see a new tab called Develop .

Develop option in Safari menu bar on Mac

Show page source code:

Now that you have enabled this developer mode, you can access the source code of a web page in three different ways:

With the web page open, go to Develop in the menu bar and select Show Page Source .
On the web page for which you want to see the source code, press the Option + Command + U keys simultaneously.
This is probably the easiest option. Simply Control-click or right-click on an empty area of the page and select Show Page Source .

Show Page Source using right-click in Safari on Mac

When performing any of these actions, the source code of the page will then appear at the bottom of your Safari window. From there, you can inspect all you want.

On iPhone or iPad

If you want to view a web page’s source code from your iPhone or iPad, you will want to use an app to assist you. Most modern apps make this process easy and include useful syntax highlighting so you can better understand what you’re looking at.

We recommend using HTML Viewer Q , which is a free download from the App Store. Once installed, follow these steps to view a web page’s source code:

1) Launch HTML Viewer Q and tap the Link button at the top right of the app.

2) Enter the full URL of a web page you want to see the source code of, then tap the Go button. We will use Amazon for this example.

3) Once the page loads, tap on the Code button at the top left of the app.

You are now viewing the source code of the web page you selected. You can tap any of the numbers at the top of the app to change between different font sizes, i.e., 9pt, 12pt, 16pt, etc., and you can also use the Search button to search for any keywords or syntax you might be specifically looking for.

The app also lets you copy the HTML code so you can paste it into any other app.

This feature empowers the Curious Georges out there with the ability to see what makes a web page tick, but this is also an invaluable tool for web developers, novice or experienced, who want a better understanding of the code behind a web page or simply want to troubleshoot their own site.

View Source Code in Safari with an Action Extension

Developed by Paul Hudson, View Source is a $0.99 Universal app that, as the name largely implies, lets you view the source code for webpages (HTML, CSS, and JavaScript) in iOS’ Safari with an action extension.

In the years I’ve been running MacStories and since I switched to the iPad as my primary device, I’ve often needed to debug problems on the site by looking at its source code output. Before I figured I could use Python to fetch a page’s source, I was forced to ask my colleagues or my web developer to grab the source code for me because “I was on the iPad”. In spite of iPhones and iPads being required test devices for web developers these days, Apple never added native developer features to iOS that wouldn’t need a Mac to work. I was stuck with my Python scripts and help from friends over iMessage.

With iOS 8 extensions, apps like View Source can be possible thanks to direct integration with Safari and access to the DOM . Once enabled in the browser’s share sheet, View Source will bring up a full-screen panel with source code you can read and copy. A share button lets you copy all text to the clipboard, send as email, or choose one from eight themes that include dark backgrounds and lighter styles. All these themes support syntax highlighting – a better visualization than my old scripts that didn’t support highlighting at all.

If you don’t want to run View Source as an extension (though that’s the biggest advantage), you can also use it as a standalone app. In that case, the app will simply let you browse websites manually (just like Linky ).

I wish that View Source could do more. Notably, there is no support for search or browsing of specific HTML tags, which combined with the lack of line-wrapping makes it difficult to read source code as you need to constantly scroll horizontally on the screen (especially a problem on the iPhone’s smaller screen in portrait mode). I’m hoping that a text reflow mode will be added soon, and I wouldn’t mind the more advanced options for viewing source code found in Mac apps such as Coda .

View Source isn’t perfect, but it’s a good start. Being able to view source code directly in Safari is a much better experience than having to use a dedicated app that’s not your main browser. Once again, developers are still figuring out the best ways to work with extensions in iOS 8, and View Source is yet another example of these new possibilities.

View Source is $0.99 on the App Store .

5 Ways to View Page Source on iPhone or iPad [Inspect]

It is quite easy to view HTML page source code on Windows PC or Mac, but you don’t always hold your computer. For iOS users, you always have your iPhone around. It would be more convenient to view page source on iPhone or iPad. Actually, you can do it without third-party apps.

In this post, I will show you 5 ways to show webpage source code on iOS devices and even inspect elements. Sounds great? Keep reading to learn how.

Method 1: Create a View Source Shortcut

The first I recommend is to create a View Source shortcut that is available in Share Sheet, so you can easily access it from Safari. Shortcuts is a stock app in iOS 13 or new versions for automation. There are many amazing pre-made shortcuts that you can get from the internet.

Here I will show you how to make one to view HTML source code step by step. You can refer to the steps below or the video. If you don’t want to make it by yourself, you can also click this link to add it to your Shortcuts Library.

Step 1. Open the Shortcuts on your iPhone or iPad. Tap on the “+” icon to create a new one.

Step 2. Tap on the three-dot icon and enable the option “Show in Share Sheet”. Tap Done to go back to the new shortcut.

Step 3. Type “html” in the search bar and drag the “Make HTML from Rich Text” action from the search results to the shortcut.

Step 4. Type “quick look” in the search bar and drag the “Quick Look” action to the shortcut.

Step 5. Tap “Done” to save the shortcut and change the shortcut name to “View Source”.

Step 6. Go to Safari and open the web page where you want to view the source code. Tap the Safari Share button and select the “View Source” shortcut that you just created.

Shortcuts only accept Safari web pages, so if you want to view source code on Chrome or other web browsers, keep reading to find other alternative methods.

Method 2: Safari Bookmark Trick

Another way to view source code is via Safari bookmark. You can use bookmark to run a javascript and it will show the source code of any web page.

Step 1. Copy the script. You can go to this Github page and copy the script or copy the script below.

Step 2. Tap your browser (Chrome or Safari) Share button and select Add Bookmark. It doesn’t matter which web page you add. You just need to create a new bookmark for further usage.

Step 3. Tap on the Bookmark icon and locate the new bookmark that you just created.

Step 4. From there, tap Edit and change the new bookmark name to “View Page Source” and the URL to the script that you copied before.

Step 5. Go to the webpage where you want to view source code. Tap the Bookmark icon and select the View Page Source bookmark that you just saved.

Then it will display the source code of that web page. If you use Chrome, it is even simpler because you can change the bookmark URL on Step 2.

Method 3: DevTools Extension for Safari

If you also need to inspect elements, you can use a Safari extension for iPhone or iPad. There are a few of extensions that allows you to inspeact elements, including DevTools Extension, Web Inspector, and Achoo HTML Viewer & Inspector (Paid).

Let me take DevTools Extension as an example to show you how:

Step 1. Open AppStore and search for “DevToools Extension” or simply click on this link to install it.

Step 2. Once installed, go to Settings Safari > Extensions to enable DevTools Extension.

Step 3. Open Safari and visit any web page that you want to inspect. Tap on the AA icon from the address bar and select DevTools Extension.

Step 4. You will see a gear icon on the page. Tap on it and you will see the Developer Tools like on Desktop browser. When done, you can always click on the gear icon again to close Developer Tools.

Method 4: A Nice Browser That Spports View Source

Unfortunately, Chrome for iOS does not allow viewing page source. Alternatively, You can use Via Browser. It is a nice browser for iPhone and iPad that allows you to view page source and inspect elements.

Via Browser is also available for Android, so you can also use it to view page source on Android . Once you have the browser, you can tap the three bars icon on the bottom right and select Tools > View Source. It will open a new tab with the source code of your current page.

In addition, Via browser enables you to run userscripts and change user agent. As you know, some web apps only works on Desktop. If you use Via browser to change user agent to MacOS or Windows, then you can use Desktop web app on your iPhone or iPad.

Method 5: View Source App for iOS

You can also download a dedicated app for viewing HTML source code. For that, I recommend the free app View Source , which is designed for iPhone. Once you installed this app, you will see an option View Source in your Web Browser (Safari or Chrome) Share Sheet. You can simply tap on it to see the source code.

In addition, it can also work as a standalone app. Within the app, you can input any webpage URL and the app will load its source code automatically.

These 5 methods all work great on iOS devices. You can use any of them to view page source on iPhone or iPad based on your preference. For me, I prefer the Shortcuts method because Shortcuts allows you to customize it for all kinds of possibilities.

How to view the HTML source code of a website on a Mac

How to view source code on a pc, how to view the html code of a particular page element, how to download an entire website source code.

Why is important to know how to view a website’s source code?

Key Learnings

It’s always useful to know how to view the source code of your website or any website. It’s a skill that can prove very handy when working on your SEO, troubleshooting problems, or just curious to see what the HTML source code of a website looks like.

In this post, you’ll learn easy methods on how to see the code of any website on any platform. Let’s get started.

To view the source of a website on a Mac using Safari, navigate to the page you want and use the following keyboard shortcut: Option+Command+U.

Alternatively, you can right-click anywhere on the page and select “Show Page Source” from the dropdown menu.

Google Chrome

To view the source code of a website on a Mac using Chrome, navigate to the page you want and use the keyboard shortcut: Option+Command+U.

You can also right-click on the page and select “View Page Source” from the dropdown menu.

View Website Source Code Using Chrome on a Mac

When using Firefox on a Mac, the keyboard shortcut to view the source code is: COMMAND + U

When using Google Chrome on a PC, you can view the source code of a website by using the keyboard shortcut: CTRL + U.

When using Firefox on a PC, the keyboard shortcut to view the source code is: CTRL + U

When using Opera on a PC, the keyboard shortcut to view the HTML source code of a page is: CTRL + U

Microsoft Edge

The keyboard shortcut to view the source code of a page when using the Microsoft Edge browser on a PC is: F12 & CTRL+SHIFT+I

Instead of viewing the HTML code of a whole page, you can view the code of particular page elements using the INSPECT ELEMENT option available in all popular browsers like Google Chrome, Firefox, and Safari.

The process is straightforward. Open the page in a new browser window and then highlight a section of the page using the mouse.

Right-click and then select INSPECT from the dropdown menu.

This will open the developer tools and show you the HTML code associated with the particular element or page section.

Here is a quick demo of how to do this using Google Chrome.

To download a website’s HTML source code, navigate using your favorite browser to the page, and then select SAVE PAGE AS from the FILE menu. You’ll then be prompted to select whether you want to download the whole page (including images) or just the source code.

The download options are common for all browsers.

Web Page, Complete: Downloads the page source code and all images, CSS files, and js script associated with the particular page. All files are saved in a folder. This is useful when you need to download the images together with the HTML code.

Web Page, Single File: Downloads the page in MHTML (short for MIME HTML). This is a form of HTML that includes both the website’s code and any external resources.

Web Page, HTML Only: Downloads the HTML and any other elements (like embedded Java Script Code) found in the body of a page.

Why is important to know how to view a website’s source code?

There are many use cases where you might want to check the source code of a website, the most common are:

Check for the occurrence of H1 tags – Best SEO practices indicate a page should have only one H1 tag . To check if this is the case with your website, you can navigate to one of your posts, and using any of the methods described above, you can view the HTML source code of the page. You can then search for <h1> and see if there is more than one H1 tag on the page.

Check if links are nofollow – One of the ways to find out if a link has the nofollow tag added (which makes it less important for SEO rankings) is to view the HTML code of a page and check for the occurrence of the word ‘nofollow’ within the <a></a> element. You can do this to check the links on your website or any other website.

Optimize your website for speed – A good reason for analyzing your website’s source code is when optimizing your page speed . As a starting point, you can view the HTML of a page and try to identify elements (including JS and CSS files) that can be removed to make the page size smaller and faster to download. Then with the help of other tools (like Google’s PageSpeed Insights ), you can continue optimizing your code further.

It’s very easy to view or save the source code of a webpage. The process is the same for all browsers. The first step is to navigate to the page you want and then you can view the HTML using a keyboard shortcut.

You can optionally download the code in a text file. To view the HTML code of a particular page element, use the INSPECT function that is part of the developer’s tools.

How to View Web Page Source Code on iPhone: 5 Ways

A source code is something that every developer is familiar with. In fact, they play with source codes every day. While carrying out your work on a PC or a laptop, it is easy as a pie to check the source code of any web page or website. Just right-click and you have the option right on your screen. Similarly, when you are using an Android phone, browsers like Chrome give the option to view the source code of any web page easily.

But this is not the case when you are working with an iPhone or an iPad. If you own an iPhone, and you get an urgent requirement to check the source code of any web page, you feel helpless and you have to go through the whole process of opening your PC, visiting that web page, and then inspecting it. This whole process is irritating and surely takes a lot of time. And at that time you wish if it was possible to inspect the same web page using the Safari browser of my iPhone.

Well, to your surprise, yes it is possible to view the HTML source code of any web page right through your iPhone’s Safari app. Although it’s not as simple as in Android phones, we have shared some tips and tricks that will help you out. So use these methods and the next time some web page fascinates you and you want to inspect it, just do it using your iPhone or iPad.

Table of Contents

1. Use Web Inspector Safari extension on iPhone

There is a new Safari extension available for iPhone and iPad which comes by the name Web Inspector. It is recently launched after the iOS 15 update. This extension is the most advanced web inspector tool that has ever made for the mobile smartphones till now. Why we are saying this is because it gives you features which are available in the desktop browser inspector tool. You can not only view the source code of a web page but also inspect particular HTML elements in the DOM, run codes in the console, check network requests and resources used by the web page and much more.

Here’s how you can use the Web Inspector extension on Safari browser to view page source code on your iPhone or iPad –

First, install the Web Inspector from the App Store. It is available for free and would take just few seconds to download as the size is very small.
Once installed, you will see the app added to your home screen. Click on it to open and then it will ask to allow Safari extension from the settings.
Open the Settings on your iPhone or iPad and go to Safari .

To check the source code, open the Safari app and visit the web page.

If you go to the Elements tab, there you can check more details of the element such as attributes, styles, and even computed style like you see on the desktop browsers. You can also make edits in the HTML source code of the web page, apply the changes and see the live preview.

2. Create a view source shortcut for Safari

In this method, we will using Shortcuts app on iPhone to create a shortcut for viewing the source code on Safari. This is very technical method and you will need to be attentive while following the steps. To start with, first find and open the Shortcuts app and tap the plus button at the top right corner. In the next screen, give a name to your shortcut like View source or whatever you want.

After that, tap the three dots in the upper right corner which will open a pop up box on your screen. Enable the Show in Share Sheet button and click the Done option.

Set the type of content you want to receive from the Share Sheet to Safari web pages only by clicking on the Any option on the Receive command. Make sure to clear all other inputs.

Now tap the + Add Action button and search for Make HTML from Rich Text . Click on it to add it to the shortcut.

Search for another action named Quick Look using the search bar at the bottom and add it also. This is how the final page will look like –

Now you have successfully create a shortcut for viewing source code of any web page on Safari browser. To use it, visit the web page you want to inspect and click the share button at the bottom. Swipe it up and click on the View Source option that you created with the Shortcuts app. This will open a pop up box where you will see the HTML source code of the web page.

3. Safari bookmark trick to view page source

This is the old school method which used to the only way to view the source code on iPhone before when there are no extensions available for Safari browser. This method would require you to use a script code and save it as bookmark on Safari. Then you simply need to open the bookmark on the web page you want to inspect. Here’s a detailed guide on this method –

First of all, open the Safari browser on your iPhone or iPad and visit any web page. Click on the share button (a square with an arrow pointing upward) at the bottom. Next, click on the Add bookmark option and then save it. Now you need to go to the Bookmarks, click the Edit option and then choose the bookmark you have recently saved. Change it name to something like “ View source ” and replace the address field with the below code.

Now all the technical part is done. Whenever you want to view the source code of a web page, simply open it, go to the Bookmarks and click on the new bookmark you have created to run the script. You will then see the code all over your screen. The drawback of this method is that it doesn’t highlight the HTML elements in different colors so it become little difficult to find what you are looking for.

4. Use Google’s webpage cache to view source

If you don’t want to install a third party extension on your phone or don’t use any method that involves script to view the source code of a webpage on your iPhone or iPad then this method is for you. Here will use the Google’s cache version of the web page to view its HTML source code.

For those who don’t know, Google save a cached copy of all web pages that are indexed on it. You can publicly access this cached version by adding cache: before the address of the web page. This is all what you have to do in this method.

Simply, open the Safari browser on your iPhone or iPad and visit the web page or website whose source code you want to view. After that, click on the URL tab and add cache: at the starting. As you visit the link, it will take you to Google’s cache page. Make sure there is no space after cache: otherwise you will land on Google search page instead. The next thing you have to do is to click on the View source option.

Please note that this method will only show the web page as it appeared the last time when Google crawled it. In the meantime, the current page could have changed so you won’t get to see the updated HTML source code with this method until the Google crawl the web page again.

5. Use View Source application

Although we have shared enough methods for this topic but this last one is for those people who wants to use a specific application for viewing the source code of the web pages on their iOS device. There is an app named View Source which you can find on the App Store. You simply need to install this app on your phone, open it and enter the URL of the web page you want to inspect. It will then instantly show the HTML source code. As simple as that!

Another feature that this app has is the direct integration with the Safari browser. When you browsing on Safari and instantly need to view the source of a web page, just click on the share button and swipe the pop up to reveal all options. You will find View Source there. Clicking on that will open a pop-up window where you will see the source code of the web page.

So these are some methods which you can use to view the page source in Safari browser on your iPhone or iPad. Out of all these, using the Web Inspector extension is the best one as it gives you other useful features also which are available on desktop browser. Other than that, you can also use Google’s cache method to quickly view the source code of any web page without installing any app or extension on your device. Let us know which method your personally liked that you will use. If you are facing any problem, feel free to share it in the comments below.

How to View the Source Code of a Web Page

View a web page's source code to diagnose errors

What to Know

On most major browsers, you can access a site's source code by pressing Ctrl + U in Windows.
On a Mac, press Cmd + Option + U within most major browsers or Cmd + U in Firefox.
On Android, use the view-source: URL tweak to view source code. On Safari for iOS, this isn't supported.

Although web browsers interpret the Hypertext Markup Language files and Cascading Style Sheets that make the web appear as it does, a hotkey or URL tweak forces browsers to display the source code of that page in a new tab or window. Although most people rarely need to examine the source code, developers use this perspective to troubleshoot layout inconsistencies or to fix bugs on a website.

How to View Source in a Desktop Browser

For all the major desktop browsers — Google Chrome , Microsoft Edge , Mozilla Firefox, Opera, Vivaldi—press Ctrl+U to open a new tab that displays the raw HTML of the page you're on. On a Mac , press Cmd+Option+U or Cmd+U in Firefox.

Alternatively, all desktop browsers support a URL-specific tweak. Prepend the text view-source: to the URL to open the page in Source mode. For example, type view-source:https://www.lifewire.com to view the source code behind Lifewire's main landing page.

Prefer a mouse, or need to tweak the HTML on the fly? All the main browsers support a View Source command somewhere within its menu structure, and they also support a developer mode (named various things, and launched various ways) that permits real-time tweaking to how a page executes based on changes you make in the developer interface.

How to View Source on a Default Mobile Browser

The stock Android browser allows the view-source: URL tweak. On iOS, however, the stock Safari app does not support this feature. On Apple's platform, you'll need to launch a different browser or a source-code viewing app from the App Store.

Individual mobile browsers that you installed from your platform's app store behave differently. Consult the browser's documentation for specific procedures.

Thank you. Liking this better than FF which I've used forever, but having an iPad and iPhone it really necessitates I use Safari Desktop so that my bookmarks are all sync'd up. Bye bye FF.

Thanks John

Sep 21, 2012 1:22 PM in response to Steven Shmerler

You're welcome, and FYI if you encounter one of those ill-conceived websites that refuse to load unless you're running some version of Exploder or whatever, you will find the ability to change the "user agent" in the Develop menu also.

Sep 21, 2012 3:09 PM in response to John Galt

Yup. Saw that. Very cool. Can't believe I've been using FF all these years.

Thanks, but I hate that opening @ the bottom. I am not a developer, I just need to see a table so I can copy it off a suppliers website. How can I get it to open in a new window like before? It's a royal pain to find what I want, as I have to scroll sideways forever. While I like ML, there are so many changes that suck that I wish Apple never made. this is one of them. I'll use FF for my source needs.

If you ask politely and omit your rude comments, I will answer.

Otherwise you can figure it out for yourself.

Great Tip! Thank you very much! I never knew you could change the user agent too! I was simply looking for an option to view a page's source when i came across this post.

Thanks again!

Is there a way of viewing the source code for a website all in one page like in the old version of Safari?

I'm trying to get a facebook like button to work and for some reason all my HTML appears on a single line in the developer box thing, it makes it really hard to find what it is that I need to fix 😟

Sep 11, 2013 7:33 AM in response to tom-young

After you set your preferences to show the Develop menu and you select "Show Page Source" from the Develop menu, you get a new window of source

And being a new window you can open it as wide as your monitor allows. You can also widen or reduce the width of the two right and left panels to open the center panel more.

I'm checking now for a "wrap" feature which authoring editors usually have so you don't have endless strings going to the right beyond the visible page, but can't find one. I suggest you post a new thread on this subject so you get the attention this deserves. I'd love to know this too.

Dec 1, 2013 6:48 AM in response to Chris Winkler1

To find the source code of the table off that suppliers website:

"show page source"

Then click "inspect" on the menu bar

Then go to the place on the suppliers website where you'd like to find the code and click the section.

You'll see the code highlighted in the page source menu.

Hope that helps

Mar 15, 2014 7:04 PM in response to John Galt

Hi John. Forgive the naive question... You mentioned being able to change the "user agent". Why is that important, and when might that come in handy?

Mar 16, 2014 12:41 AM in response to Mike_Scott

All that changing the User Agent accomplishes is to placate poorly written web pages that interrogate the client to determine which browser it's using. There is no reason to do that, but some pages will refuse to load unless the user agent string matches the arbitrary value it expects.

Change the string to whatever it wants, and the page will obediently load having determined exactly nothing about what features the browser may or may not be capable of supporting .

It looks like Safari version 8 under Yosemite no longer has this choice. Is there any way, either through third-party software or other way in the new version of Safari?

Feb 20, 2015 4:04 AM in response to Kenneth Nielsen

Hi Kenneth,

I am running Safari Version 8.0.3 (10600.3.18) and Yosemite and was able to perform this operation. as mentioned above: Safari menu > Preferences... (⌘,) > Advanced

Check "Show Develop menu in men bar" and close Safari's preferences. If this does not work, try restarting your browser, but normally you should then see the "Develop" drop down menu in the bar between "Bookmarks" and "Window". Finally click Show Page Source.

Optimizing WebKit & Safari for Speedometer 3.0

Apr 10, 2024

by Alan Baradlay, Antti Koivisto, Matt Woodrow, Patrick Angle, Ryosuke Niwa, Vitor Ribeiro Roriz, Wenson Hsieh, and Yusuke Suzuki

The introduction of Speedometer 3.0 is a major step forward in making the web faster for all, and allowing Web developers to make websites and web apps that were not previously possible. In this article, we explore ways the WebKit team made performance optimizations in WebKit and Safari based on the Speedometer 3.0 benchmark.

In order to make these improvements, we made an extensive use of our performance testing infrastructure. It’s integrated with our continuous integration , and provides the capability to schedule A/B tests. This allows engineers to quickly test out performance optimizations and catch new performance regressions.

Improving Tools

Proper tooling support is the key to identifying and addressing performance bottlenecks. We defined new internal JSON format for JavaScriptCore sampling profiler output to dump and process them offline. It includes a script which processes and generates analysis of hot functions and hot byte codes for JavaScriptCore. We also added FlameGraph generation tool for the dumped sampling profiler output which visualizes performance bottlenecks. In addition, we added support for JITDump generation on Darwin platforms to dump JIT related information during execution. And we improved generated JITDump information for easy use as well. These tooling improvements allowed us to quickly identify bottlenecks across Speedometer 3.0.

Improving JavaScriptCore

Revising megamorphic inline cache (ic).

Megamorphic IC offers faster property access when one property access site observes many different object types and/or property names. We observed that some frameworks such as React contain a megamorphic property access. This led us to continuously improve JavaScriptCore’s megamorphic property access optimizations: expanding put megamorphic IC, adding megamorphic IC for the in operation, and adding generic improvements for megamorphic IC.

Revising Call IC

Call IC offers faster function calls by caching call targets inline. We redesigned Call IC and we integrated two different architectures into different tiers of Just-In-Time (JIT) compilers. Lower level tiers use Call IC without any JIT code generation and the highest level tier uses JIT code generatiton with the fastest Call IC. There is a tradeoff between code generation time and code efficiency, and JavaScriptCore performs a balancing act between them to achieve the best performance across different tiers.

Optimizing JSON

Speedometer 3.0 also presented new optimization opportunities to our JSON implementations as they contain more non-ASCII characters than before. We made our fast JSON stringifier work for unicode characters . We also analyzed profile data carefully and made JSON.parse faster than ever .

Adjusting Inlining Heuristics

There are many tradeoffs when inlining functions in JavaScript. For example, inline functions can more aggressively increase the total bytecode size and may cause memory bandwidth to become a new bottleneck. The amount of instruction cache available in CPU can also influence how effective a given inlining strategy is. And the calculus of these tradeoffs change over time as we make more improvements to JavaScriptCore such as adding new bytecode instruction and changes to DFG’s numerous optimization phases. We took the release of the new Speedometer 3.0 benchmark as an opportunity to adjust inlining heuristics based on data collected in modern Apple silicon Macs with the latest JavaScriptCore.

Make JIT Code Destruction Lazy

Due to complicated conditions, JavaScriptCore eagerly destroyed CodeBlock and JIT code when GC detects they are dead. Since these destructions are costly, they should be delayed and processed while the browser is idle. We made changes so that they are now destroyed lazily, during idle time in most cases.

Opportunistic Sweeping and Garbage Collection

In addition, we noticed that a significant amount of time goes into performing garbage collection and incremental sweeping across all subtests in both Speedometer 2.1 and 3.0. In particular, if a subtest allocated a large number of JavaScript objects on the heap, we would often spend a significant amount of time in subsequent subtests collecting these objects. This had several effects:

Increasing synchronous time intervals on many subtests due to on-demand sweeping and garbage collection when hitting heap size limits.
Increasing asynchronous time intervals on many subtests due to asynchronous garbage collection or timer-based incremental sweeping triggering immediately after the synchronous timing interval.
Increasing overall variance depending on whether timer-based incremental sweeping and garbage collection would fall in the synchronous or asynchronous timing windows of any given subtest.

At a high level, we realized that some of this work could be performed opportunistically in between rendering updates — that is, during idle time — instead of triggering in the middle of subtests. To achieve this, we introduced a new mechanism in WebCore to provide hints to JavaScriptCore to opportunistically perform scheduled work after the previous rendering update has completed until a given deadline (determined by the estimated remaining time until the next rendering update). The opportunistic task scheduler also accounts for imminently scheduled zero delay timers or pending requestAnimationFrame callbacks : if it observes either, it’s less likely to schedule opportunistic work in order to avoid interference with imminent script execution. We currently perform a couple types of opportunistically scheduled tasks:

Incremental Sweeping : Prior to the opportunistic task scheduler, incremental sweeping in JavaScriptCore was automatically triggered by a periodically scheduled 100 ms timer. This had the effect of occasionally triggering incremental sweeping during asynchronous timing intervals, but also wasn’t aggressive enough to prevent on-demand sweeping in the middle of script execution. Now that JavaScriptCore is knowledgable about when to opportunistically schedule tasks, it can instead perform the majority of incremental sweeping in between rendering updates while there aren’t imminently scheduled timers. The process of sweeping is also granular to each marked block, which allows us to halt opportunistic sweeping early if we’re about to exceed the deadline for the next estimated rendering update.
Garbage Collection : By tracking the amount of time spent performing garbage collection in previous cycles, we’re able to roughly estimate the amount of time needed to perform the next garbage collection based on the number of bytes visited or allocated since the last cycle. If the remaining duration for performing opportunistically scheduled tasks is longer than this estimated garbage collection duration, we immediately perform either an Eden collection or full garbage collection . Furthermore, we integrated activity-based garbage collections into this new scheme to schedule them at appropriate timing.

Overall, this strategy yields a 6.5% total improvement in Speedometer 3.0 *, decreasing the time spent in every subtest by a significant margin, and a 6.9% total improvement in Speedometer 2.1 *, significantly decreasing the time spent in nearly all subtests.

Various Miscellaneous Optimizations for Real World Use Cases

We extensively reviewed all Speedometer 3.0 subtests and did many optimizations for realistic use cases. The examples include but are not limited to: faster Object.assign with empty objects , improving object spread performance , and so on.

Improving DOM code

Improving DOM code is Speedometer’s namesake, and that’s exactly what we did. For example, we now store the NodeType in the Node object itself instead of relying on a virtual function call. We also made DOMParser use a fast parser, improved its support of li elements , and made DOMParser not construct a redundant DocumentFragment . Together, these changes improved TodoMVC-JavaScript-ES5 by ~20%. We also eliminated O(n^2) behavior in the fast parser for about ~0.5% overall progression in Speedometer 3.0. We also made input elements construct their user-agent shadow tree lazily during construction and cloning , the latter of which is new in Speedometer 3.0 due to web components and Lit tests. We devirtualized many functions and inlined more functions to reduce the function call overheads. We carefully reviewed performance profile data and removed inefficiency in hot paths like repeated reparsing of the same URLs .

Improving Layout and Rendering

We landed a number of important optimizations in our layout and rendering code. First off, most type checks performed on RenderObject are now done using an inline enum class instead of virtual function calls , this alone is responsible for around ~0.7% of overall progression in Speedometer 3.0.

Improving Style Engine

We also optimized the way we compute the properties animated by Web Animations code. Previously, we were enumerating every animatable properties while resolving transition: all . We optimized this code to only enumerate affected properties. This was ~0.7% overall Speedometer 3.0 progression. Animating elements can now be resolved without fully recomputing their style unless necessary for correctness.

Speedometer 3.0 content, like many modern web sites, uses CSS custom properties extensively. We implemented significant optimizations to improve their performance. Most custom property references are now resolved via fast cache lookups, avoiding expensive style resolution time property parsing. Custom properties are now stored in a new hierarchical data structure that reduces memory usage as well.

One key component of WebKit styling performance is a cache (called “matched declarations cache”) that maps directly from a set of CSS declarations to the final element style, avoiding repeating expensive style building steps for identically styled elements. We significantly improved the hit rate of this cache.

We also improved styling performance of author shadow trees, allowing trees with identical styles to share style data more effectively.

Improving Inline Layout

We fixed a number of performance bottlenecks in inline layout engine as well. Eliminating complex text path in Editor-TipTap was a major ~7% overall improvement. To understand this optimization, WebKit has two different code paths for text layout: the simple text path, which uses low level font API to access raw font data, and the complex text path, which uses CoreText for complex shaping and ligatures. The simple text path is faster but it does not cover all the edge cases. The complex text path has full coverage but is slower than the simple text path.

Previously, we were taking the complex text path whenever a non-default value of font-feature or font-variant was used. This is because historically the simple text path wouldn’t support these operations. However, we noticed that the only feature of these still missing in the simple text path was font-variant-caps . By implementing font-variant-caps support for the simple text path , we allowed the simple text path to handle the benchmark content. This resulted in 4.5x improvement in Editor-TipTap subtest, and ~7% overall progression in Speedometer 3.0.

In addition to improving the handling of text content in WebKit, we also worked with CoreText team to avoid unnecessary work in laying out glyphs. This resulted in ~0.5% overall progression in Speedometer 3.0, and these performance gains will benefit not just WebKit but other frameworks and applications that use CoreText.

Improving SVG Layout

Another area we landed many optimizations for is SVG. Speedometer 3.0 contains a fair bit of SVG content in test cases such as React-Stockcharts-SVG. We were spending a lot of time computing the bounding box for repaint by creating GraphicsContext, applying all styles, and actually drawing strokes in CoreGraphics. Here, we adopted Blink ’s optimization to approximate bounding box and made ~6% improvement in React-Stockcharts-SVG subtest. We also eliminated O(n^2) algorithm in SVG text layout code, which made some SVG content load a lot quicker .

Improving IOSurface Cache Hit Rate

Another optimization we did involve improving the cache hit rate of IOSurface. An IOSurface is a bitmap image buffer we use to paint web contents into. Since creating this object is rather expensive, we have a cache of IOSurface objects based on their dimensions. We observed that the cache hit rate was rather low (~30%) so we increased the cache size from 64MB to 256MB on macOS and improved the cache hit rate by 2.7x to ~80%, improving the overall Speedometer 3.0 score by ~0.7%. In practice, this means lower latency for canvas operations and other painting operations.

Reducing Wait Time for GPU Process

Previously, we required a synchronous IPC call from the Web Process to the GPU process to determine which of the existing buffers had been released by CoreAnimation and was suitable to use for the next frame. We optimized this by having the GPUP just select (or allocate) an appropriate buffer, and direct all incoming drawing commands to the right destination without requiring any response. We also changed the delivery of any newly allocated IOSurface handles to go via a background helper thread , rather than blocking the Web Process’s main thread.

Improving Compositing

Updates to compositing layers are now batched , and flushed during rendering updates, rather than computed during every layout. This significantly reduces the cost of script-incurred layout flushes.

Improving Safari

In addition to optimizations we made in WebKit, there were a handful of optimizations for Safari as well.

Optimizing AutoFill Code

One area we looked at was Safari’s AutoFill code. Safari uses JavaScript to implement its AutoFill logic, and this execution time was showing up in the Speedometer 3.0 profile. We made this code significantly faster by waiting for the contents of the page to settle before performing some work for AutoFill. This includes coalescing handling of newly focused fields until after the page had finished loading when possible, and moving lower-priority work out of the critical path of loading and presenting the page for long-loading pages. This was responsible for ~13% progression in TodoMVC-React-Complex-DOM and ~1% progression in numerous other tests, improving the overall Speedometer 3.0 score by ~0.9%.

Profile Guided Optimizations

In addition to making the above code changes, we also adjusted our profile-guided optimizations to take Speedometer 3.0 into account. This allowed us to improve the overall Speedometer 3.0 score by 1~1.6%. It’s worth noting that we observed an intricate interaction between making code changes and profile-guided optimizations. We sometimes don’t observe an immediate improvement in the overall Speedometer 3.0 score when we eliminate, or reduce the runtime cost of a particular code path until the daily update of profile-guided optimizations kicks. This is because the modified or newly added code has to benefit from profile-guided optimizations before it can show a measurable difference. In some cases, we even observed that a performance optimization initially results in a performance degradation until the profile-guided optimizations are updated.

With all these optimizations and dozens more, we were able to improve the overall Speedometer 3.0 score by ~60% between Safari 17.0 and Safari 17.4. Even though individual progressions were often less than 1%, over time, they all stacked up together to make a big difference. Because some of these optimizations also benefited Speedometer 2.1, Safari 17.4 is also ~13% faster than Safari 17.0 on Speedometer 2.1. We’re thrilled to deliver these performance improvements to our users allowing web developers to build websites and web apps that are more responsive and snappier than ever.

How-To Geek

Ms-dos 4.0 from 1988 is now open-source software.

Break out that IBM PC.

Microsoft Disk Operating System, or MS-DOS for short, was the operating system that powered early PCs and served as the underlying framework for early versions of Microsoft Windows. Some older versions have been released as open-source software over the past few years, giving us a better look at early computing history, and now the code for the 1988 release of MS-DOS 4.0 is available.

Microsoft has just released the code for version 4.0 of MS-DOS . The operating system was released in 1988, 36 years ago, and was a notable upgrade from earlier releases. For example, it added support for hard drive partitions up to 2GB. Microsoft had also planned this version of MS-DOS to be multitasking-capable and actually shipped a "multitasking" version of the OS to some markets, but IBM had other plans for the release, so it wasn't too widespread.

Being such an old operating system, open sourcing this is not something that's actually "useful" in the same way as most other open source software. This is more about preserving the history of computers than anything else, since MS-DOS 4.0 isn't all that useful even in the world of retro computing. Many applications and DOS-based games require MS-DOS 5.0 or 6.0, and the last public release of MS-DOS 6.22 is usually the best choice. There's also FreeDOS , which is an open-source DOS clone that has been under development since 1994, and can run nearly all applications and drivers intended for MS-DOS.

Microsoft released the source code of some of the very first versions of MS-DOS years ago, so it's nice to see the company also give the same treatment to some later MS-DOS versions. It also makes us wonder whether Microsoft might actually choose to open-source in the same manner some of the earlier versions of Windows in the long term. This particular version of MS-DOS was released a little less than two years before the release of Windows 3.0 in 1990, largely considered to be the very first successful release of Windows. It's something we'd definitely be interested in checking out.

Ten years ago, Microsoft released the source for MS-DOS 1.25 and 2.0 to the Computer History Museum, and then later republished them for reference purposes. This code holds an important place in history and is a fascinating read of an operating system that was written entirely in 8086 assembly code nearly 45 years ago.

Today, in partnership with IBM and in the spirit of open innovation, we’re releasing the source code to MS-DOS 4.00 under the MIT license. There’s a somewhat complex and fascinating history behind the 4.0 versions of DOS, as Microsoft partnered with IBM for portions of the code but also created a branch of DOS called Multitasking DOS that did not see a wide release.

MS-DOS 4.00

Explore the source code, binaries, and documents on GitHub

A young English researcher named Connor “Starfrost” Hyde recently corresponded with former Microsoft Chief Technical Officer Ray Ozzie about some of the software in his collection. Amongst the floppies, Ray found unreleased beta binaries of DOS 4.0 that he was sent while he was at Lotus. Starfrost reached out to the Microsoft Open Source Programs Office (OSPO) to explore releasing DOS 4 source, as he is working on documenting the relationship between DOS 4, MT-DOS, and what would eventually become OS/2. Some later versions of these Multitasking DOS binaries can be found around the internet, but these new Ozzie beta binaries appear to be much earlier, unreleased, and also include the ibmbio.com source.

Scott Hanselman, with the help of internet archivist and enthusiast Jeff Sponaugle, has imaged these original disks and carefully scanned the original printed documents from this “Ozzie Drop”. Microsoft, along with our friends at IBM, think this is a fascinating piece of operating system history worth sharing.

Jeff Wilcox and OSPO went to the Microsoft Archives, and while they were unable to find the full source code for MT-DOS, they did find MS DOS 4.00, which we’re releasing today, alongside these additional beta binaries, PDFs of the documentation, and disk images. We will continue to explore the archives and may update this release if more is discovered.

Thank you to Ray Ozzie, Starfrost, Jeff Sponaugle, Larry Osterman, Mark Zbikowski, our friends at the IBM OSPO, as well as the makers of such digital archeology software including, but not limited to Greaseweazle, Fluxengine, Aaru Data Preservation Suite, and the HxC Floppy Emulator. Above all, thank you to the original authors of this code, some of whom still work at Microsoft and IBM today!

If you’d like to run this software yourself and explore, we have successfully run it directly on an original IBM PC XT, a newer Pentium, and within the open source PCem and 86box emulators.

Why code-testing startup Nova AI uses open source LLMs more than OpenAI

It is a universal truth of human nature that the developers who build the code should not be the ones to test it. First of all, most of them pretty much detest that task. Second, like any good auditing protocol, those who do the work should not be the ones who verify it.

Not surprisingly, then, code testing in all its forms — usability, language- or task-specific tests, end-to-end testing — has been a focus of a growing cadre of generative AI startups. Every week, TechCrunch covers another one like Antithesis (raised $47 million) , CodiumAI (raised $11 million) and QA Wolf (raised $20 million). And new ones are emerging all the time, like new Y Combinator graduate Momentic.

Another is year-old startup Nova AI , an Unusual Academy accelerator grad that’s raised a $1 million pre-seed round. It is attempting to best its competitors with its end-to-end testing tools by breaking many of the Silicon Valley rules of how startups should operate, founder/CEO Zach Smith tells TechCrunch.

Whereas the standard Y Combinator approach is to start small, Nova AI is aiming at mid-size to large enterprises with complex code-bases and a burning need now. Smith declined to name any customers using or testing its product except to describe them as mostly late-stage (Series C or beyond) venture-backed startups in e-commerce, fintech or consumer products, and “heavy user experiences. Downtime for these features is costly.”

Nova AI’s tech sifts through its customers’ code to build tests automatically using GenAI. It is particularly geared toward continuous integration and continuous delivery/deployment (CI/CD) environments where engineers are constantly shipping bits and pieces into their production code.

The idea for Nova AI came from the experiences Smith and his co-founder Jeffrey Shih had when they were engineers working for big tech companies. Smith is a former Googler who worked on cloud-related teams that helped customers use a lot of automation technology. Shih previously worked at Meta (also at Unity and Microsoft before that) with a rare AI specialty involving synthetic data. They’ve since added a third co-founder, AI data scientist Henry Li.

Another rule Nova AI is not following: While boatloads of AI startups are building on top of OpenAI’s industry-leading GPT, Nova AI is using OpenAI’s Chat GPT-4 as little as possible. No customer data is being fed to OpenAI.

While OpenAI promises that the data of those on a paid business plan is not being used to train its models, enterprises still do not trust OpenAI, Smith tells us. “When we’re talking to large enterprises, they’re like, ‘We don’t want our data going into OpenAI,” Smith said.

The engineering teams of large companies are not the only ones that feel this way. OpenAI is fending off a number of lawsuits from those who don’t want it to use their work for model training, or believe their work wound up, unauthorized and unpaid for, in its outputs.

Nova AI is instead heavily relying on open source models like Llama developed by Meta and StarCoder (from the BigCoder community, which was developed by ServiceNow and Hugging Face), as well as building its own models. They aren’t yet using Google’s Gemma with customers, but have tested it and “seen good results,” Smith says.

For instance, he explains that OpenAI offers models for vector embeddings. Vector embeddings translate chunks of text into numbers so the LLM can perform various operations, such as clustering them with other chunks of similar text. Nova AI doesn’t use OpenAI’s embeddings and instead uses open source for this on the customer’s source code. It uses OpenAI tools only to help it generate some code and to do some labeling tasks, and is going through lengths not to send any customer data into OpenAI.

“In this case, instead of using OpenAI’s embedding models, we deploy our own open source embedding models so that when we need to run through every file, we aren’t just sending it to OpenAI,” Smith explained.

While not sending customer data to OpenAI appeases nervous enterprises, open source AI models are also cheaper and more than sufficient for doing targeted specific tasks, Smith has found. In this case, they work well for writing tests.

“The open LLM industry is really proving that they can beat GPT 4 and these big domain providers, when you go really narrow,” he said. “We don’t have to provide some massive model that can tell you what your grandma wants for her birthday. Right? We need to write a test. And that’s it. So our models are fine-tuned specifically for that.”

Open source models are also progressing quickly. For instance, Meta recently introduced a new version of Llama that’s earning accolades in technology circles and that may convince more AI startups to look at OpenAI alternatives.
