Supabase
Open-source Firebase alternative built on PostgreSQL
About Supabase
Supabase is an open-source backend-as-a-service platform built on PostgreSQL that provides instant REST and GraphQL APIs, authentication with row-level security, real-time subscriptions, file storage, edge functions, and vector embeddings. It offers a complete backend stack that can be self-hosted or used as a managed cloud service, giving developers full SQL flexibility without vendor lock-in.
Pros & Cons
Pros
- Built on PostgreSQL — full SQL power with extensions, no proprietary query language to learn
- Open-source and self-hostable, eliminating vendor lock-in concerns
- Generous free tier with 500MB database and 50K MAU that works for real development and small production apps
- Auto-generated REST and GraphQL APIs dramatically reduce boilerplate backend code
- Excellent developer experience with clear documentation, native SDKs for JS, Flutter, Swift, and Kotlin
- Built-in spend cap on Pro plan prevents surprise billing overages
Cons
- Requires SQL and relational database knowledge — steeper learning curve than NoSQL alternatives like Firebase
- Free tier projects pause after one week of inactivity, limiting always-on hobby use cases
- Real-time performance can degrade with large datasets or high-frequency change streams
- No built-in analytics dashboard — requires third-party tools for usage insights
- Community-only support on free tier with variable response times on Discord
