Any self-hosted Firebase alternatives?

I just recently discovered Firebase, and watched a video of how Firebase can complement AngularJS application. I was super excited, right until I realized, that Firebase only available as a hosted service, and as such, is not an option for my employer. I'd like to ask if anyone is aware of a framework or a library, offering a comparable feature set (i.e. auto-binded madel back-end persistence combined with a real-time push) Any information would be great.
