Verdict
Best for most teams: Supabase
Supabase offers a PostgreSQL foundation with full SQL power, row-level security, database migrations, and open-source self-hosting that gives developers complete data ownership and flexibility. Firebase provides rapid prototyping with offline-first SDKs, ML Kit integration, crash reporting, and deep Google Cloud ecosystem connectivity. Teams that need relational data modeling, complex queries, and transparent pricing at scale will prefer Supabase's open-source approach. Mobile-first developers building apps that require offline support and quick prototyping should choose Firebase for its mature SDK and Google Cloud integration.
Frequently Asked Questions
Is Supabase better than Firebase?
Supabase is better for projects requiring relational databases, SQL queries, and open-source flexibility. Firebase is better for rapid prototyping, mobile apps with offline support, and teams already invested in the Google Cloud ecosystem.
Can I migrate from Firebase to Supabase?
Yes, but it requires significant effort due to different data models. Firebase uses NoSQL collections while Supabase uses PostgreSQL tables. You will need to redesign your data schema and rewrite queries during migration.
Does Supabase have offline support?
Supabase has limited offline support compared to Firebase. Firebase's SDK includes built-in offline persistence, while Supabase currently relies on client-side caching strategies and does not yet have an equivalent offline-first SDK.
Is Supabase truly free?
Supabase offers a generous free tier with unlimited API requests, 500 MB database, 1 GB file storage, and 2 GB bandwidth. It remains free without requiring a credit card, unlike Firebase which requires billing for some free tier features.
