Pros & cons
Firebase
- Dual NoSQL databases: Firestore + Realtime Database
- Mature mobile/web BaaS ecosystem
- Realtime + auth + storage out of the box
- Deep Google Cloud integrations
- NoSQL model — not SQL/Postgres
- Vendor lock-in concerns
- Query flexibility can frustrate SQL-first teams
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
