[OP / Firebase founder here] We certainly aren't trying to be disingenuous with the 'serverless' title. The piece of code on GitHub allows you to build WebRTC functionality that doesn't require you to run a signaling sever. (or, any server if you want to go that far) Though, yes, we still run and maintain the Firebase servers to make this happen.<p>Sorry for any confusion. I'll add some explicit language in the README on GitHub.<p>Thanks for checking out the code.
