Editorial Verdict

AI-researched, not hands-on tested

Supabase is an open-source Firebase alternative built on real Postgres, not a proprietary database — the practical upside is you can self-host it or export your data without lock-in. The free tier is genuinely usable for small projects (500MB database, 50,000 monthly active users), but free projects pause after a week of inactivity, which matters if you're prototyping something you won't touch daily. Pro starts at $25/mo with metered overage on usage past the included limits.

Supabase bundles a Postgres database, authentication, auto-generated APIs, file storage, and edge functions into one backend-as-a-service platform, aimed at developers who want Firebase's convenience without giving up SQL and open standards. Because it's standard Postgres underneath, existing Postgres tooling, extensions, and migration scripts mostly just work.

Pricing (verified at supabase.com/pricing)

Free — $0/mo, 500MB database, 50,000 monthly active users, 5GB egress. Free projects auto-pause after a week of inactivity, capped at 2 active projects per account.
Pro — from $25/mo (first project included, additional from $10/mo). Usage-based overage past included limits — e.g. $0.00325 per additional MAU, $0.125/GB over the included disk.
Team — from $599/mo, adds SOC2/ISO 27001 and SSO.
Enterprise — custom pricing.

Where it's strong

Developers who want a real Postgres database with batteries-included auth/storage/APIs, and who value being able to self-host or migrate away without vendor lock-in.

Where to be careful

The free tier's auto-pause on inactive projects can surprise anyone using it for an infrequently-touched side project, and Pro-tier overage charges mean actual cost scales with real usage, not just the $25 sticker price.
