Frequently Asked Questions

Is Supabase a Firebase alternative?

Yes, Supabase is often called "the open source Firebase alternative." It provides similar features (database, auth, storage) but uses PostgreSQL instead of NoSQL.

Is Supabase free?

Supabase offers a generous free tier including 500MB database storage, 50K monthly active users, and 1GB file storage. Projects pause after 1 week of inactivity on free tier.

Should I use SQL or NoSQL for my app?

For most applications, SQL (Supabase/Postgres) is the better choice due to its flexibility with queries and data relationships. NoSQL (Firebase) is better for simple document storage or real-time chat apps.

Can I migrate from Firebase to Supabase?

Yes, Supabase provides migration tools to move your data from Firebase. The main challenge is converting your NoSQL data model to relational tables.
