Supabase earns a 4.6/5 — one of our highest-rated picks for solo founders. Open source — no vendor lock-in. The free tier makes it an easy recommendation for anyone starting out.
About Supabase
Supabase is the open-source Firebase alternative that gives you a Postgres database, authentication, real-time subscriptions, storage, and edge functions — all from one dashboard. For solo developers building web and mobile applications, it's the fastest path from idea to production backend.
The free tier is genuinely excellent: 500MB database, 1GB file storage, 50,000 MAUs for auth, 500,000 edge function invocations. For a typical side project or early-stage startup, this serves hundreds of daily active users at $0.
What makes Supabase special is the developer experience built on Postgres. You get auto-generated REST and GraphQL APIs, row-level security, real-time subscriptions, and database functions. Unlike Firebase's NoSQL, you get proper relational data with joins, constraints, and ACID transactions.
Auth supports email/password, magic links, phone OTP, and 20+ OAuth providers — all free. Storage handles file uploads with image transformations. Edge Functions run Deno/TypeScript at the edge.
Pro ($25/month) provides 8GB database, 100GB bandwidth, daily backups. You can also self-host the entire stack on your infrastructure using Docker, avoiding vendor lock-in.
Limitations: real-time subscriptions have connection limits on free tier, the dashboard can be slow for large databases. But for solo founders needing a database backend, Supabase is the strongest recommendation.
