shadcn/ui
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.
What is shadcn/ui?
