Who is this best for?

This is the fastest way to decide whether Supabase Auth is in the right neighborhood.

Best for
  • Teams building on Supabase's full platform where authentication integrates natively with Postgres Row Level Security — the auth token automatically scopes database access to the correct tenant or user without application-layer checks.
  • Full-stack applications that want authentication, database, storage, and edge functions from one platform with a single API key and a unified dashboard.
  • Projects that want to start on Supabase's generous free tier (50K MAUs included) and scale to paid plans gradually — the auth economics are included in the base platform cost rather than metered separately.
Who should avoid
  • Enterprise SSO and SCIM provisioning are immediate requirements
  • You need maximum CIAM flexibility and enterprise integrations now
  • Your stack is mobile-first and heavily invested in Firebase ecosystem
  • You want cloud-provider primitives and minimal platform coupling
  • You need workforce IAM governance (Okta/Entra use case)
