The Editorial Verdict
The clearest escape route from Firebase lock-in. You get a real Postgres database instead of a proprietary NoSQL store, plus auth, storage, and edge functions in one stack. Self-hosting is genuinely possible but not trivial — the compose file is heavy and you'll want a proper VPS. For most people the managed free tier is the better starting point.
