FAQ

Common questions

What tech stack does MantleKit use?

MantleKit is built on Next.js with the App Router, TypeScript, Tailwind CSS, and Shadcn/UI. It uses Supabase for database and auth, with support for Stripe, Lemon Squeezy, and Polar for payments.

Can I use MantleKit without a database?

Yes. Set database: false in your config and MantleKit runs as a fully static site with MDX blog, landing pages, and support content — no server needed.

How do themes work?

Themes are CSS variable + layout override folders. Switch themes by changing one line in your config file. All components are theme-aware, so your content adapts automatically.
