I created a similar proof of concept recently. We need to inspect the webpage displayed on a Chrome based "kiosk" running behind a firewall. We have an existing socket (or socket IO binary) connection, and my proof of concept "attaches" the Chrome remote debugging port to listen on the socketIO connection - See the youtube video in the readme to see it in action. https://github.com/joshribakoff/devtools-proxy

The tool linked in the OP looks a lot more user friendly, but perhaps my example code will be of use to someone who wants something [overly] simple.
