Supabase vs. Firebase for SaaS MVPs
Firebase wins for rapid prototyping and real-time mobile apps. Supabase wins when you need SQL, Row-Level Security, and a codebase you can reason about.
Firebase and Supabase are the two dominant BaaS platforms for MVPs. The choice shapes your architecture for years.
Firebase
- Battle-tested real-time with Firestore
- Excellent Flutter and mobile SDKs
- Fast to prototype with flexible schema
- Google's infrastructure
- NoSQL scaling complexity for relational data
- Pricing unpredictable at scale
- Vendor lock-in — hard to migrate
- No SQL, no joins
Supabase
- Postgres — SQL, joins, foreign keys, RLS
- Row-Level Security baked in
- Open source — self-host or migrate
- Predictable pricing on storage/compute
- Smaller ecosystem vs Firebase
- Real-time less mature than Firestore
- Supabase team smaller than Google
Mobile-first app with simple data model: Firebase. Multi-tenant SaaS with relational data and compliance requirements: Supabase.
