What it is
Supabase Auth is GoTrue (the open-source library) bundled into the Supabase platform. Email + password, social logins, magic links, MFA, anonymous auth. Tightly integrated with Postgres RLS — auth.uid() is available inside row-level security policies. Free with Supabase free tier.
Best for
- Apps already on Supabase where auth is one of several services
- Teams that want to own the user database
- Postgres + RLS workloads where auth.uid() is the policy primitive
- Cost-sensitive teams at any scale
When not to pick it
Skip Supabase Auth if your stack is not Supabase — using GoTrue standalone works but you lose the platform integration. Skip if you need pre-built UI components polished to Clerk's level.
My take
For Supabase-stack apps, this is the right answer by default. The integration with RLS is the differentiator. UI polish is the trade-off — you build it yourself or use Clerk on top.
