Supabase powers our entire backend infrastructure — from seamless user authentication to reliable file storage and secure secrets management with Vault. Supabase Storage was a game-changer for our AI workflow engine's reliability. Thank you for building such a developer-friendly platform!

Loved and watch-outs

Themes that recur in makers' words and Hacker News comments, each linked to what it summarises.

Supabase
Most loved
  • One project covers Postgres, auth, storage and realtime, so a solo founder ships without stitching vendors or hiring a backend team. PHPH 2PH 3PH 4
  • It is real Postgres with SQL, row-level security and pgvector rather than a proprietary store. PHPH 2PH 3PH 4
  • Open source and self-hostable, which reduces vendor lock-in. PHPH 2HNPH 3
Watch-outs
  • Row-level security policies are hard to get right, so many apps end up exposing data publicly. HNHN 2HN 3HN 4
  • Reliability has been shaky for some, and it is not really built for self-hosting in practice. HN
  • Per-project billing adds up for developers running many small side projects. HN
