## Frequently Asked Questions

**Q: When does Supabase become expensive?**
A: Typically at 100K+ MAU or heavy database usage. Pro plan starts at $25/mo but can scale to $500+/mo. Custom backend has more predictable costs.

**Q: Can I migrate from Supabase later?**
A: Yes, it's Postgres-based so data migration is straightforward. Application code needs refactoring to remove Supabase SDK dependencies.

**Q: What about Supabase edge functions?**
A: Good for simple serverless functions. Limited compared to full backend frameworks for complex business logic, job queues, or heavy processing.
