FAQ

Good questions.Clear answers.

What is included in the foundation?

One Next.js application with authentication, billing, a dashboard, Docs, Blog, and a project CLI. Explore the feature guides to see how they fit together.

Is this a hosted service or source code?

You receive the source code and run it in your own provider accounts. Follow the managed deployment guide to publish the application.

How does billing work?

Choose Stripe or Polar in your app’s configuration for lifetime purchases and monthly or yearly subscriptions. Verified webhooks connect payments to saved access. The pricing demo uses example plans. Choose Stripe test mode or Polar sandbox, then try a lifetime purchase or subscription. No real charges. Create an account first to keep your demo access and open Billing after checkout. Follow the Stripe setup or Polar setup to connect your own provider account.

Can I customize the product and design?

Yes. Change the routes, components, styles, copy, plans, and product logic in your codebase. Start with the customization guide.

What do I need before launch?

Connect your provider accounts, configure the application, and verify authentication and billing on your deployed URL. The Vercel guide walks through the setup and launch checks.
