We started using Firebase when it just launched, primarily because the top end plan said $200 for (almost) unlimited use. For what we were doing at that time this was a huge deal. Firebase have changed their pricing a couple of times since then. All said and done it's still a great service and we use Firebase in almost all our projects.
Maybe unrelated, but at the same time we started using Firebase, we started using (then) another startup called Intercom (www.intercom.io). Intercom was priced a flat $ 49 (or 50, do not remember exactly) then and it was a bargain for us. But since then Intercom has changed their pricing so many times that we ended up paying more for Intercom than for all our servers put together. Intercom is again a great service but we stopped using it because it wasn't worth the price.
