I am writing the first messenger for android, is it worth using Firebase?

Question

Android

I chose it as a topic for a course project, but I want to do something worthwhile, initially I looked at Firebase as a miracle pill, but I met a lot of criticism in its address (especially for large applications)
Is it worth using it or is there any worthy alternative for a small project
Before that, I only wrote instant messengers using VK and Telega apics, but this is generally different

Answer 1

for a course project (even a standing one) is suitable.

Answer 2

Firebase is just right for small tasks. Be careful only with the pricing - if you go beyond the limit, then it just falls out into errors instead of normal notifications (at least six months ago it was like that).

Answer 3

You can, it will also be a plus to sew your domain into the application, for example myapp.com and put a redirect to firebase, so if you go beyond the limits, you can direct the user to another firebase instance or to your server or back and forth, so you get the switch on the domain side, not the application side. For each country of the user, you can raise your own instance and not overpay for the limits.
Also look towards tarantool from mail.ru, it is great for your purposes.
