Automerge is a great project, but it feels still way to academic in it's setup. If you need a superior DX and CRDT-based full-stack database, I'd recommend you to look at Triplit.dev and their docs. (while development has decreased somewhat, the product is in a fully-featured phase and should work well for anything from small to medium, probably also very large projects depending on your configuration). Give it a try, you will like it.

Triplit is my favorite local-first database. However, it doesn't compete in the same space as Automerge, which is doc-based. If you want a user-friendly alternative, I'm launching my proposal this week: https://docnode.dev
