Gitter uses a proprietary websocket protocol built on top of the Bayeux protocol: https://docs.cometd.org/current/reference/

More details can be found on the developer site: https://developer.gitter.im/docs/faye-endpoint

We also have an open-source IRC bridge: https://github.com/gitterHQ/irc-bridge

I prefer matterbridge :) Supports more than IRC, and supports multiple gateways at once: https://github.com/42wim/matterbridge/

Depending on the availability of a Bayeux client for Golang, it looks like something that could be integrated quite easily.

I don't know how Gitter support in matterbridge is implemented but it is great! Do try it out. I've been running a three-way discord+gitter+irc gateway for a long time.

And there is a matrix.org/gitter bridge already in use by riot.im
