Microsoft Edge (EdgeHTML) Developer Tools
The Microsoft Edge (EdgeHTML) DevTools are built with TypeScript, powered by open source, optimized for modern front-end workflows, and now available as a standalone Windows 10 app in the Microsoft Store!
For more on the latest features, check out DevTools in the latest update of Windows 10 (EdgeHTML 18).
The Microsoft Edge (EdgeHTML) DevTools include:

- A Network panel to monitor and inspect requests and responses from the network and browser cache
- A Performance panel to profile the time and system resources required by your site
- A Memory panel to measure your use of memory resources and compare heap snapshots at different states of code runtime
- A Storage panel for inspecting and managing your web storage, IndexedDB, cookies and cache data
- A Service Workers panel for managing and debugging your service workers
- An Emulation panel to test your site with different browser profiles, screen resolutions, and GPS location coordinates

Microsoft Store app
The Microsoft Edge (EdgeHTML) DevTools are now available as a standalone Windows 10 app from the Microsoft Store, in addition to the in-browser (
F12) tooling experience. With the store version comes a chooser panel for attaching to open local and remote page targets and a tabbed layout for easy switching between DevTools instances.
To debug a page locally, simply launch the Microsoft Edge DevTools app. The Local panel of the chooser will display all of the active EdgeHTML content processes, including open Edge browser tabs, running PWAs (
WWAHost.exe processes), and webview controls. Click on your desired target to attach and open a new tab instance of the DevTools.
The Microsoft Edge DevTools app introduces basic support for debugging pages on a remote machine via our newly released DevTools Protocol. With the latest release comes remote access to core functionality in the Debugger, Elements (for read-only operations), and Console panels. Remote debugging is limited to Microsoft Edge (EdgeHTML) running desktop hosts, with support for other EdgeHTML hosts and Windows 10 devices coming in future releases.
Please send us your feedback so we can continue improving the Microsoft Edge (EdgeHTML) DevTools for you! Simply open the tools (
F12) and click the Send feedback button.
These shortcuts control the main DevTools window and should work across all tools.
