Self hosted analogue of firebase (ready-made backend with authorization and database) with local database replication in the client, what are the options?

Question

Database

It's hard to find tags for a question.
I need a simple self hosted analogue of firebase / AWS amplify.
The main thing you need is user and database authentication, ideally with a ready-made client in JS, offline work is needed.

Found from the options rxdb + couchDB for replication, but as I understand it, couchDB does not have a thing a la user registration, you need to start users yourself.

In general, all this, of course, can be done with a regular backend and manually screwed up the replication of the client copy of the database, but it’s just laziness, firebase suits everyone, except that the RKN started blocking it and you need to get off it.

All this is necessary for PWA.

Why not make a bicycle?)
In general, I also found https://appwrite.io/ - according to the description, it seems to be just what you need. Both the database and authentication with users are there.
