Supabase
Top pickPostgres with Firebase's ergonomics — and you can take the database with you.
Supabase wraps a real Postgres database in the things that made Firebase pleasant: instant REST and GraphQL APIs, row-level security, authentication, file storage, realtime subscriptions and edge functions. The difference that matters is underneath. Your data is in Postgres, so you get SQL, joins, transactions, extensions like PostGIS and pgvector, and the ability to pick up the database and run it on any host on earth. It is Apache-2.0 and self-hostable with Docker Compose, and the hosted tier exists for people who would rather not. Around 107k GitHub stars and pushed to daily.
What it does well
- +Real Postgres — SQL, joins, transactions and the whole extension ecosystem
- +Genuinely portable: the database runs anywhere, hosted or not
- +Apache-2.0 with a complete self-host path, not a crippled community edition
- +pgvector built in, so AI features do not need a second database
Where it falls short
- −You now have a Postgres database to think about — indexes, connections, vacuum
- −Mobile offline sync is weaker than Firebase's SDKs
- −Self-hosting the full stack is more moving parts than the hosted product suggests
- −Younger than Firebase; some edges are still being filed off
