Free MIT
The foundation for your design system — beautifully designed components you can customize and own.
Overview
shadcn/ui is an open-source collection of re-usable, beautifully designed UI components built on Radix UI and Tailwind CSS. Unlike traditional component libraries, you copy-paste the component code directly into your project — giving you full ownership and the ability to customize everything. It has become the de-facto standard React component library with 107K+ GitHub stars, chart components, blocks, and a growing ecosystem.
Best Suited For
"React and Next.js developers who want a flexible, fully customizable component foundation with premium design and zero vendor lock-in."
Advantages
- You own the code — components are copy-pasted into your project, not installed as a black-box dependency.
- 107K+ GitHub stars make it the most popular React component collection, with a vast community ecosystem of extensions and themes.
- Radix UI primitives ensure full ARIA accessibility compliance, RTL support, and keyboard navigation out of the box.
Limitations
- Not a traditional npm package — each component requires manual integration into your project.
- Tightly coupled to Tailwind CSS v4 for styling, limiting use outside Tailwind projects.
