Supabase
Auth & InfrastructureOpen-source Firebase alternative with a real Postgres database, instant REST/GraphQL APIs, auth, storage, edge functions, and realtime subscriptions.
Supabase is an open-source backend-as-a-service platform built on actual PostgreSQL, providing auto-generated REST and GraphQL APIs, authentication (email, OAuth, magic links), object storage with CDN, Edge Functions powered by Deno, and real-time WebSocket subscriptions -- all without vendor lock-in since you can self-host or migrate away. Its commitment to open standards with Row Level Security policies for fine-grained access control makes it attractive for teams wanting Firebase-like speed with relational database power. The generous free tier includes 500MB database and 50K auth users with no time limit, while the Pro plan at $25/month adds production-grade features, though bandwidth and compute costs can scale significantly.
Best for
Developers and startups building modern web or mobile applications who want PostgreSQL's power with Firebase-like simplicity and need to ship production-ready backends quickly without managing infrastructure.

Strengths & Weaknesses
Strengths
Real PostgreSQL database with full SQL capabilities, advanced queries, triggers, and extensions—no proprietary NoSQL limitations
Generous free tier with no time expiration includes 500MB database, 50K auth users, and full feature access for unlimited projects
Auto-generated REST and GraphQL APIs from database schema eliminate boilerplate API code and speed up development significantly
Open-source with self-hosting option provides complete data ownership and eliminates vendor lock-in concerns
Row-level security policies enable sophisticated access control directly in the database without complex middleware
Weaknesses
Free tier projects pause after 7 days of inactivity, requiring manual reactivation which can cause unexpected downtime
Bandwidth costs ($0.09/GB) and auth MAU overages ($0.00325/user) can escalate quickly for high-traffic applications with media content
Database-direct frontend access pattern requires careful RLS configuration and may not suit complex multi-tenant architectures
Compute upgrades are expensive ($110-$960/month for dedicated instances) compared to self-managed Postgres on cloud providers
