Supabase vs Firebase
Supabase is a Postgres-based open-source Firebase alternative with predictable SQL; Firebase is Google's mature BaaS with Firestore (NoSQL). Both allow commercial use on free tier.
Key differences
- Database: Supabase = Postgres (SQL); Firebase = Firestore (NoSQL document store).
- Open source: Supabase is fully self-hostable; Firebase is proprietary.
- Free tier: Supabase pauses inactive projects after 7 days; Firebase Spark stays on but has strict quotas.
- Outbound HTTP: Cloud Functions on Firebase require Blaze paid plan; Supabase Edge Functions on free tier.
