Supabase
Open-source backend with Postgres, auth and vector search
The verdict
Supabase is a backend-as-a-service built on Postgres, giving apps a database, authentication, storage and vector search with little setup. It positions as an open-source alternative to proprietary backends.
What it is
Supabase gives a project a production Postgres database plus authentication, file storage, auto-generated APIs and real-time subscriptions, so a frontend can have a real backend quickly. Its pgvector support adds vector search, which makes it a common choice for AI apps and agent memory. Being Postgres-based and open-source means data stays portable and SQL skills transfer. The tradeoffs: you take on more database thinking than a fully managed abstraction, scaling Postgres well needs care, and free-tier projects pause after inactivity.
Strengths
- Real Postgres database, so SQL knowledge and data portability carry over
- Built-in authentication, storage and auto-generated APIs reduce backend setup
- pgvector support enables vector search for AI features and agent memory
Trade-offs
- Requires more database thinking than a fully abstracted backend service
- Scaling Postgres well under load needs care and some expertise
- Free-tier projects pause after a period of inactivity, which can surprise hobby users
Best for
Full-stack and AI app builders who want a real SQL database plus auth and vector search fast
Not for
Teams that want a fully abstracted backend and prefer not to think in SQL or manage Postgres

What people build with it
Frequently asked
- What is Supabase?
- A backend-as-a-service built on Postgres. It gives an app a database, authentication, storage, auto-generated APIs and real-time features with minimal setup.
- Can Supabase do vector search for AI?
- Yes. Its pgvector support stores and queries embeddings, which is why it is a common backend for AI apps, retrieval-augmented generation and agent memory.
- Supabase or Firebase?
- Supabase is Postgres-based and open-source, so SQL skills and data portability carry over. Firebase uses a proprietary NoSQL model. The choice often comes down to relational versus document data.
- Why do free Supabase projects pause?
- On the free tier, projects pause after a period of inactivity to manage resources. The Pro tier removes auto-pause and adds more compute and storage.
- Does Supabase replace a frontend host?
- No. It is the backend. Teams commonly pair it with a frontend cloud like Vercel or Netlify to deploy the user-facing app.
