A year ago when I rewrote my startup's product in AngularJS I was on the fence between Firebase and Parse. Built prototypes against both and ended up going with Firebase for a few reasons - 1: price, 2: owned by Google and not FB and 3: the whole 3 way data binding thing.
Awesome to see them releasing code for the backend but I'm finding this trend really disturbing - relying on 3rd party services for everything.
Doesn't anyone remember back in the day (like 5 years ago hah) when programmers / admins actually bought software and ran it on their own servers and didn't "rent" it? I know, crazy right? To own software and if the company went under, things could still be fine for a while longer.
Maybe it's time to consider my use of Firebase and go back to the way things used to be.
