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
