# Supabase Auth Migration Plan

## Why Supabase?
- ✅ **Self-hosted Docker** - Full control, no external dependencies
- ✅ **Built-in Auth** - JWT tokens, social login (Google), user management
- ✅ **Simple API** - Similar to Auth0 but simpler
- ✅ **PostgreSQL** - Uses your existing database
- ✅ **React SDK** - Easy frontend integration
- ✅ **No Tailwind issues** - Doesn't affect frontend build

## Migration Steps

### 1. Add Supabase to Docker Compose
- Add Supabase services (Auth API, PostgREST, GoTrue)
- Configure to use existing PostgreSQL database
- Set up environment variables

### 2. Update Backend
- Replace Auth0 SDK with Supabase client
- Update JWT validation to use Supabase keys
- Simplify auth routes

### 3. Update Frontend
- Replace `@auth0/auth0-react` with `@supabase/supabase-js`
- Update Login component
- Update App.tsx auth logic

### 4. Database Migration
- Keep existing user table structure
- Add Supabase auth tables (if needed)
- Map `auth0_sub` → `supabase_user_id`
