#7 this week, scoring 7.5 out of 10. Best for Teams already using or planning to use Supabase as their backend platform who want integrated auth with their database and APIs.
- Developer Experience 8
- Clean API and good integration with Supabase SDKs, though documentation could be more comprehensive for complex scenarios.
