🔄 Replacing Supabase with Your Own Postgres Setup (Advanced)

If you prefer full control, you can swap Supabase with your own hosted PostgreSQL database.

Set Up Your Own Postgres Database

Use a managed service like:

• Render
• Neon
• DigitalOcean
• Or host it yourself.

Make sure to configure:

• Database URL
• Authentication method
• Allowed IPs
• SSL if needed

Update Your Environment Variables

Instead of Supabase variables, use a direct Postgres connection string:

DATABASE_URL=postgresql://user:password@host:port/database

You can either:

• Use Prisma ORM
• Or build your own queries using a library like pg

✅ Why It’s Set Up This Way

NextNative uses Supabase only for convenience. But everything is decoupled, so you can fully swap out the database layer without touching your Auth, or frontend logic.
