Frequently Asked Questions

MantleKit is built on Next.js (App Router) with TypeScript, Tailwind CSS, and Shadcn/UI. Database and auth are powered by Supabase. You can choose between Stripe, Lemon Squeezy, or Polar for payments, and Resend or Mailgun for transactional email.

The Starter and Pro tiers include a personal licence for your own projects (unlimited). For building products for clients, you'll need the Agency tier ($249), which includes an unlimited commercial licence.

Themes are CSS variable-based with layout overrides. Change one line in your mantle.config.ts and your entire application transforms. No component duplication, no messy overrides—just clean, maintainable theming.

No. The Landing tier ($49) works with database: false, giving you a fully static site with MDX blog, landing pages, and support pages. Auth and dynamic features require database: true (Starter and above).

All tiers include access to our community Discord and documentation. Pro and Agency tiers get priority email support with a 24-hour response time. We also publish regular tutorials and guides on our blog.
