Build full-stack Next.js apps with AI
Describe the app and Supacode writes it in Next.js with pages, server code and API routes. Connect your own Supabase project for data and sign-in, watch the app run in a live preview, and deploy it to your own Vercel account.
Opens the composer with this prompt filled in. Edit it before you build; the credit cost shows before anything runs.
How it works
Describe the app
Explain the pages, the data and who can do what. Choose Next.js in the stack picker.
Connect Supabase
Connect your Supabase project in the Backend tab. Supacode writes migrations and runs them only after you approve.
Deploy
Deploy to your own Vercel account from the Publish menu, or push the code to GitHub.
What you can ask for
- App Router pages and layouts
- API routes and server code
- Sign-in and per-user data with Supabase
- Database migrations you approve
- Deploy to your own Vercel
Example prompt: A Next.js app with sign-in: users can create, edit and delete notes, notes are saved in a Supabase database, and each user only sees their own notes.

Questions
Does the preview run server code?
Yes. Next.js projects run in a sandboxed preview, so you can test pages and API routes before you deploy.
Who owns the database and hosting?
You do. The database is your own Supabase project and the deployment goes to your own Vercel account.
Can I export the project?
Yes. Download it as a zip or push it to GitHub and keep working anywhere.
