Pros & cons

PostgreSQL

  • Gold-standard open-source SQL engine
  • Huge extension ecosystem (including vectors)
  • Foundation for many modern BaaS platforms
  • You assemble auth/storage yourself
  • Ops complexity grows without a managed host
  • Not a serverless product by itself

Supabase

  • Full Postgres with rich SQL ecosystem
  • Auth, storage, realtime in one platform
  • Self-host or managed cloud
  • Operational complexity grows with scale
  • Edge latency depends on region choice
  • Not the lightest option for tiny apps
