The open source Firebase alternative with Postgres
Open-source Postgres backend platform with auth, storage, realtime, and edge functions.
Postgres under the hood means you can use any standard SQL tool and your existing knowledge transfers directly
The free tier is genuinely generous — 500MB database and 2GB storage is enough to validate most SaaS ideas without spending a cent
Row-level security policies are built in, so you can ship a secure multi-tenant app without writing custom auth middleware
Auto-generated TypeScript types from your schema save hours every week and eliminate an entire class of runtime bugs
Storage, auth, edge functions, and database all in one dashboard — I stopped juggling six different services
The realtime subscriptions work out of the box and don't require any extra infrastructure like a separate Pusher account
Hitting the connection limit on the free tier (60 connections) will silently fail your app at the worst possible moment under load
Self-hosting is technically possible but the documentation is scattered and keeping up with upstream changes is a maintenance burden
Edge functions have a cold start delay that makes them unsuitable for latency-sensitive operations without warm-up tricks
The dashboard UI has had confusing UX regressions after updates that made simple tasks like inspecting RLS policies harder to find
Branching for database preview environments is still immature compared to Neon — you can't easily spin up a branch per PR
