Supabase
Open-source Firebase alternative built on Postgres.
What is Supabase?
Supabase wraps a dedicated Postgres database with instant REST and realtime APIs, authentication, file storage, edge functions, and vector search. Everything is open source and self-hostable, and because it is plain Postgres underneath, you can always drop to SQL — or leave with your data.
Our review
4.5The fastest way to stand up a real backend without giving up SQL or portability. Auth, storage, realtime, and auto-generated APIs save weeks, and it's all Postgres — no proprietary data model. Row-level security is powerful but is also where most teams make their first mistakes; learn it early.
Pros
- + Real Postgres — full SQL, no lock-in data model
- + Auth, storage, realtime, and APIs out of the box
- + Open source and self-hostable
Cons
- − Row-level security has a learning curve
- − Self-hosted feature parity trails the cloud product
