"Developer tools can use the Microsoft Edge DevTools Protocol to inspect and debug the Microsoft Edge browser. It provides a set of methods and events that are organized into different Domains of EdgeHTML engine instrumentation.
Tooling clients can call these methods and monitor these events through JSON web socket messages exchanged with the DevTools Server hosted by Edge or the Windows Device Portal. Microsoft Edge DevTools uses this protocol to enable remote debugging of a host machine running Microsoft Edge from the standalone DevTools client available from the Microsoft Store.
The Microsoft Edge DevTools Protocol is designed to align closely with the Chrome DevTools Protocol (see the W3C WICG for DevTools Protocols), though there are known interoperability gaps in this release."
