What it really isSupabase — open-source Firebase alternative built on PostgreSQL.
Our takeSupabase is a full Backend-as-a-Service platform: Postgres database, authentication, file storage, realtime subscriptions, edge functions, and vector embeddings — all open-source and self-hostable.
Supabase is developer infrastructure. The Pro plan starts at $25/month per project.
Why we rate itSupabase delivers an exceptional developer experience with generous free limits and predictable entry pricing.
The open-source core means no vendor lock-in, and the Postgres foundation satisfies complex relational needs that Firebase cannot.
The catchUsage overages on the Pro plan can accumulate unpredictably; bandwidth and compute costs require monitoring at scale.

Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: new project spins up in under 5 minutes with auto-generated REST and GraphQL APIs.
  2. Scale breakpoint
    Egress and compute overages on the Pro plan become costly past ~100K MAUs; Team plan at $599/mo is a steep jump.
  3. Walled garden
    Low: open-source core allows self-hosting; standard Postgres means full data portability.
Still a fit?
If none of these block you, start on the free plan.
