BEFORE YOU CLONE

Straight answers.

Can I use it commercially?

Yes. The project uses the MIT License, so you can use, modify, and commercialize it.

Is it a no-code builder?

No. It is a clean TypeScript codebase for builders who want ownership and the freedom to customize.

Do I need every included service?

No. Clerk, Stripe, Supabase, analytics, and other integrations can be replaced as your product evolves.

Does it deploy only to Vercel?

No. It is a standard Next.js application and can run anywhere that supports Node.js.

Start with working infrastructure.

Fork the repository, follow the guide, and spend the next few days on the part only you can build.
