Sniffing the protocol

You can inspect how the Chrome DevTools uses the protocol. Especially handy when looking up newer features. First, run Chrome with the debugging port open: 

/Applications/Google\ Chrome\ Canary.app/Contents/MacOS/Google\ Chrome\ Canary --remote-debugging-port=9222 http://localhost:9222 http://chromium.org
Then, select the Chromium Projects item in the Inspectable Pages list. Now that DevTools is up and fullscreen, open DevTools to inspect it. Cmd-R in the new inspector to make the first restart. Now head to Network Panel, filter by Websocket, select the connection and click the Frames tab. Now you can easily see the frames of WebSocket activity as you use the first instance of the DevTools.

Simultaneous protocol clients

This includes opening DevTools while another client is connected. On the bug tracker, crbug.com/129539 follows the issue; you can star it for email updates.

Upon disconnnection, the outgoing client will receive a detached event. For example: {"method":"Inspector.detached","params":{"reason":"replaced_with_devtools"}}. View the enum of possible reasons. (For reference: the original patch). After disconnection, some apps have chosen to pause their state and offer a reconnect button.
