You know how building a website can feel like a lot, especially when you’re trying to style every little thing yourself? Buttons, forms, layouts… it adds up fast. That’s where UI frameworks really save the day. They give you a bunch of premade design elements that you can just drop in and go. It’s like having a design starter pack that helps your site look clean and professional, without spending forever tweaking the details.

Mantine is a React component library with over 100 UI components and 50+ custom hooks, designed to help developers build modern, accessible, and performant UIs. It supports RTL layouts, dark mode, and complete theme customization, all while staying lightweight.

Mantine doesn’t force you into a predefined design system. You build your own style while enjoying great developer experience, full TypeScript support, and zero CSS-in-JS lock-in.
