+# Vercel Deployment Guide for Umami
+
+This guide will help you successfully deploy Umami on Vercel, especially if you're experiencing the "Database version check successful" hang issue.
+
+## Required Environment Variables
+
+### For Supabase Users
+
+You need to configure **TWO** database URLs in your Vercel environment variables:
+
+#### 1. DATABASE_URL (Connection Pooler)
+This URL uses pgbouncer for connection pooling.
+
+**Format:**
+```
+DATABASE_URL=postgresql://user:password@host.pooler.supabase.com:6543/postgres?pgbouncer=true&connect_timeout=15
+```
+
+**Important notes:**
+- Use port `6543` (pgbouncer port)
+- Include `?pgbouncer=true&connect_timeout=15` parameters
+- Host should end with `.pooler.supabase.com`
+
+#### 2. DIRECT_DATABASE_URL (Direct Connection)
+This URL connects directly to the database, bypassing pgbouncer.
+
+**Format:**
+```
+DIRECT_DATABASE_URL=postgresql://user:password@host.supabase.com:5432/postgres
+```
+
+**Important notes:**
+- Use port `5432` (direct postgres port)
+- Do **NOT** include pgbouncer parameters
+- Host should end with `.supabase.com` (without `.pooler`)
+
+### For Other PostgreSQL Providers
+
+If you're not using Supabase, you still need both environment variables:
+
+```
+DATABASE_URL=postgresql://username:password@host:port/database
+DIRECT_DATABASE_URL=postgresql://username:password@host:port/database
+```
+
+For non-pooled connections, both can be the same URL.
+
+## Additional Environment Variables
+
+Make sure you also have:
+```
+APP_SECRET=your-random-secret-key
+```
+
+## Vercel Configuration
+
+The `vercel.json` file has been configured with:
+- **Function timeout**: 300 seconds (5 minutes) to prevent build timeouts
+- **Custom build command**: Ensures database migrations run before the build
+
+## Troubleshooting
+
+### Build Still Hanging?
+
+1. **Check Database Connectivity**: Ensure your database is accessible from Vercel's network
+2. **Verify Environment Variables**: Double-check both `DATABASE_URL` and `DIRECT_DATABASE_URL` are set correctly
+3. **Check Password Encoding**: Special characters in passwords may need URL encoding
+4. **Review Vercel Logs**: Look for errors after the "Database version check successful" message
+
+### Migration Issues
+
+If you have pending migrations that are causing issues, run locally:
+
+```bash
+npx prisma migrate resolve --applied "migration_name"
+npx prisma migrate deploy
+```
+
+Then redeploy to Vercel.
+
+### Common Mistakes
+
+- ❌ Using the same port (6543) for both URLs
+- ❌ Missing pgbouncer parameters on DATABASE_URL
+- ❌ Including pgbouncer parameters on DIRECT_DATABASE_URL
+- ❌ Not URL-encoding special characters in passwords
+- ❌ Using `.pooler.supabase.com` for DIRECT_DATABASE_URL
+
+### Port Reference for Supabase
+
+| Connection Type | Port | Host Pattern | URL Parameter |
+|----------------|------|--------------|---------------|
+| Pooled (DATABASE_URL) | 6543 | `*.pooler.supabase.com` | `?pgbouncer=true&connect_timeout=15` |
+| Direct (DIRECT_DATABASE_URL) | 5432 | `*.supabase.com` | None |
+
+## Deployment Steps
+
+1. Set up both environment variables in Vercel dashboard
+2. Push your code changes (including the updated `schema.prisma` and `vercel.json`)
+3. Trigger a new deployment
+4. Monitor the build logs
+
+## Need Help?
+
+If you're still experiencing issues:
+- Check Vercel's deployment logs for specific errors
+- Verify your database is accepting connections
+- Ensure your database user has the correct permissions
+- Try connecting to your database using a PostgreSQL client to verify credentials
