FAQ
Common questions
MantleKit is built with Next.js (App Router), TypeScript, Tailwind CSS, and Shadcn/UI. Authentication and database are powered by Supabase, with your choice of Stripe, Lemon Squeezy, or Polar for payments.
The Personal licence covers your own projects. For client work, you'll need the Agency tier ($249), which includes an unlimited commercial licence for client projects.
Themes are controlled via a single line in your mantle.config.ts file. Change the theme property and your entire application updates instantly with no component changes needed.
