Shadcn
A collection of copy-paste React components built on Radix UI that you own and customize, not a traditional npm package.
What is Shadcn?
Shadcn is a collection of accessible React components that you copy directly into your codebase instead of installing as a dependency.
Built on Radix UI primitives and styled with Tailwind CSS, it gives you production-ready components with full accessibility baked in.
Most builders use the CLI to add components one at a time. The code lives in your project, so you can tweak styling, behavior, or structure however you want. No version conflicts, no waiting for maintainers to merge your PR.
Free and open source. Works with Next.js, Remix, Astro, or any React setup. The official site is ui.shadcn.com.
