Supabase

Supabase is an open-source backend with Postgres, auth, and storage. Learn why developers use it, who it's best for, and alternatives.

Why this tool?

The problem

Building backend infrastructure from scratch—database, auth, file storage, APIs—takes weeks before any user-facing feature ships.

The old way

Provision RDS, build auth from scratch with JWT and sessions, set up S3 for storage, and write API endpoints for every resource.

The better way

Supabase spins up a full Postgres backend with auth, storage, and real-time APIs in minutes, so the first week goes to product, not infrastructure.

What makes it stand out

The only BaaS built on real Postgres—meaning full SQL, extensions, foreign keys, and no vendor lock-in to a proprietary query language.

Tradeoffs to consider

Postgres expertise helps; cold starts on free tier; some advanced features still maturing compared to Firebase's longer-established ecosystem.

When not to use it

If you need a non-relational database, already have a backend team comfortable with custom infrastructure, or require a NoSQL data model.
