Hello, thanks for sharing, yes - it looks similar in its core idea, will definitely look at code base and hopefully find something interesting to learn from. One of current Centrifugo problems is that lots of features out of the box result in not so trivial client. So as far as I personally don't know Java and Objective-C/Swift there are no clients for mobile apps yet. Hopefully this will change in future with help of open-source community. Or maybe Go 1.5 mobile apps support will allow to create shared library for using from those languages.

Yeah, client support is always the hard part, there are just so many languages to support... Centrifugo seems feature-packed, though, good job!
