Supabase vs Firebase 2026: Komplett Jämförelse
Supabase and Firebase are the two dominant backend-as-a-service platforms. Both handle auth, realtime data, and file storage. But they are fundamentally different.
Jämförelse: Supabase vs Firebase
| Kriterium | Supabase | Firebase |
|---|---|---|
| Database | PostgreSQL (relational, SQL) | Firestore (NoSQL, documents) |
| Querying | Full SQL + joins + views | Collection queries only, no joins |
| Access Control | Row-Level Security (database-enforced) | Security Rules (app-enforced) |
| Realtime | WebSocket subscriptions (strong) | Native realtime sync (excellent) |
| Auth | Email, OAuth, magic link, SSO, phone | Same + Google ecosystem native |
| Pricing | Predictable (database size + bandwidth) | Per-operation (can spike) |
| Open Source | Yes — self-hostable | No (Google proprietary) |
| WeWeb Integration | Native connector | Manual API setup |
Vårt omdöme
Supabase
Better for most apps
Firebase
Better for realtime mobile
Supabase wins for: SaaS platforms, multi-tenant apps, anything with complex relational data, WeWeb frontends, and teams that want SQL.
Firebase wins for: simple real-time mobile apps, Google ecosystem products, teams already in GCP, FlutterFlow apps where Firestore DX is preferable.
At App Studio, 90% of our backends are Supabase. The PostgreSQL foundation, Row-Level Security, and predictable pricing are decisive for production SaaS.
