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.

Local debugging

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.

Remote debugging

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.

To get started, check out the Microsoft Edge DevTools section of the DevTools Protocol docs.
