LinkStart Verdict
We tested Supabase extensively and found it to be the superior choice for developers who want the speed of Firebase but the power of SQL. It eliminates backend boilerplate while keeping you strictly within the robust Postgres ecosystem.
Why we love it
- Zero-config Realtime features via WebSockets are a game-changer.
- Row Level Security (RLS) ensures frontend-to-DB connections are secure.
- No vendor lock-in; you can self-host or export your data anytime.
Things to know
- Free tier projects pause after 7 days of inactivity (cold starts).
- Self-hosting is operationally complex compared to the managed service.
- Complex realtime filters can be resource-intensive at scale.
