// NO-NONSENSE SAAS BOILERPLATE
Build faster.
Ship sooner.
A no-nonsense toolkit for developers who value function over form. Raw interfaces. Zero bloat. Maximum output.
// FEATURES
Everything you need. Nothing you don't.
Terminal-First
Built for the command line. Every action available via CLI. No GUI required.
Zero Config
Sensible defaults out of the box. Override only what you need. Convention over configuration.
Type-Safe
Full TypeScript support with generated types. Catch errors at compile time, not runtime.
Edge-Ready
Deploy to edge functions globally. Sub-50ms cold starts. No vendor lock-in.
Open Source
MIT licensed. Fork it. Modify it. Ship it. No strings attached.
Composable
Unix philosophy: small, focused modules that pipe together. Build your own stack.
// DEVELOPER EXPERIENCE
One config. Zero bloat.
- Single config file controls everything
- Tree-shakes unused features at build
- TypeScript-first with full inference
- Hot reload in under 200ms
Configure once, deploy anywhere. MantleKit reads your mantle.config.ts and strips everything you don't need.
export default {
theme: "brutalist",
database: true,
auth: {
providers: ["google", "magic-link"],
},
payments: "stripe",
email: "resend",
features: {
blog: true,
ecommerce: true,
chat: true,
},
} satisfies MantleConfig;"We believe software should be honest. No rounded corners hiding complexity. No gradients masking mediocrity. Just raw, functional interfaces that respect the developer."
-- The MantleKit Manifesto

Why Brutalist Design Wins for Developer Tools
Rounded corners and gradients are for marketing sites. Your SaaS dashboard deserves better.
// FAQ
Common questions.
Is MantleKit a template or a framework?
MantleKit is a production-ready boilerplate. You get the full source code -- no runtime dependency, no lock-in. Fork it, modify it, ship it.
Can I use MantleKit for client projects?
The Agency tier ($249) includes a commercial licence for unlimited client projects. Starter and Pro are personal-use licences.
What happens after I purchase?
You receive a licence key via email. Run npx create-mantlekit --key YOUR_KEY and the CLI handles everything: theme selection, feature flags, dependency installation.
