Microsoft Edge (Chromium) Developer Tools overview

Microsoft Edge has adopted the Chromium open-source project. The new Microsoft Edge browser creates better web compatibility and reduces the fragmentation of different web platforms. The change should make it easier for you to build and test your webpages in Microsoft Edge. The new Microsoft Edge should help your webpages work as expected when opened in other Chromium-based browsers. Chromium-based browsers include Google Chrome, Vivaldi, Opera, Brave, and the new Microsoft Edge.

The web has grown in usage across an ever-widening array of device types. The complexity and overhead involved in testing webpages has rapidly grown. Web developers like you need to test against many different systems. To ensure your webpages work well on all device types and browsers, you may find it nearly impossible, particularly if you work at a small company. The new Microsoft Edge is now based on Chromium. The Microsoft Edge team has simplified the matrix by aligning the Microsoft Edge web platform with other Chromium-based browsers. The new Microsoft Edge provides a best-in-class development experience. The experience is accomplished inside the browser and along with the other developer tools you use everyday, such as Visual Studio Code.

As a Chromium-based browser developer, you should feel comfortable with the new Microsoft Edge browser. The Microsoft Edge (Chromium) DevTools work just like the developer tools you already know and use. The Microsoft Edge (Chromium) Developer Tools are often called the Microsoft Edge (Chromium) DevTools or DevTools.

Microsoft Edge (Chromium) DevTools

If you previously developed for Microsoft Edge (EdgeHTML) and are evaluating the new Microsoft Edge, it now provides great new tools for you to build and test your webpages easier and faster.

Open the DevTools

The Microsoft Edge DevTools are a set of tools built directly into the Microsoft Edge browser. The DevTools allows you to do the following tasks all directly within the browser.

  • Inspect and make changes to your HTML webpage
  • Edit CSS and instantly see preview how your webpage renders
  • Review all of the console.log() statements from your front-end JavaScript code
  • Debug your script, set breakpoints, and step through your code line by line

More examples of the features that DevTools provide to make it easier and faster for you to build and test your webpage in Microsoft Edge.

To open the DevTools

  • Select F12
  • Select Ctrl+Shift+I (Windows/Linux) or Command+Option+I (macOS)

If you want to see the HTML or CSS for an element on your site, right-click the element and choose Inspect to jump into the Elements tool. To open the DevTools in Inspect Element Mode, select Ctrl+Shift+C (Windows/Linux) or Command+Option+C (macOS). the Inspect Element Mode allows you to choose an element on the webpage and display the HTML and CSS in the Elements tool.

If you want to review logs from your front-end JavaScript code or quickly run some script, open the Console. To launch the Console tool in the DevTools, select Ctrl+Shift+J (Windows/Linux) or Command+Option+J (macOS).

  • A Sources tool to open and edit your code, set breakpoints, step through code, and display the state of your webpage
  • A Network tool to monitor and inspect requests and responses from the network and browser cache
  • A Performance tool to profile the time and system resources required by your site
  • A Memory tool to measure your use of memory resources and compare heap snapshots at different states of code runtime
  • An Application tool to inspect, modify, and debug web app manifests, service workers, and service worker caches. You may also inspect and manage storage, databases, and caches from the Application tool.
  • A Security tool to debug security issues and ensure that you have properly implemented HTTPS on your webpage. HTTPS provides critical security and data integrity for both your site and your users that provide personal information on your site.

    • Catch common errors related to making your webpage accessible, secure, performant, and so on.
    • Fix each error.
    • Build a PWA.


The Audits panel provides links to content hosted on third-party websites. Microsoft is not responsible for and has no control over the content of these sites and any data they might collect.

You may have accessed DevTools using extensions when you diagnosed and debugged issues while you built your webpages (or apps). Microsoft Edge extensions are acquired from Microsoft Edge Add-ons. On Microsoft Edge Add-ons, browse DevTools extensions from the Developer tools category or search for a specific extension.

You may also add extensions from the Chrome Web Store.

At the top, choose Allow extensions from other stores and then choose Allow in the dialog that appears.


Extensions installed from sources other than the Microsoft Store are unverified, and may affect browser performance.

Choose Add to Chrome to add your DevTools extension to Microsoft Edge.
