FAQ
Answers to common questions.
What is MantleKit?
MantleKit is a premium Next.js SaaS boilerplate with 5 production-ready themes, built-in authentication, payment integrations, MDX blog, transactional email, and support pages. It helps you ship your SaaS product in hours instead of weeks.
Do I need to know TypeScript?
No. MantleKit works with plain JavaScript. TypeScript support is included out of the box with auto-generated types, but it is entirely optional. Use what works for you.
Can I switch themes after starting?
Yes. Themes are implemented with CSS variables and zero component duplication. Change the theme in your mantle.config.ts file and your entire app updates instantly. No code changes needed.
What payment providers are supported?
MantleKit supports Stripe, Lemon Squeezy, and Polar. The Starter plan includes one provider of your choice. The Pro plan includes all three with a common abstraction layer for easy switching.
What kind of support is available?
All plans include access to documentation, knowledge base, and community support via GitHub Discussions. The Agency plan includes priority support with a 24-hour SLA via email.
