About Shadcn UI
Shadcn UI is a collection of 50+ React components built on Radix UI primitives and styled with Tailwind CSS. You copy the component source code directly into your project rather than installing a package as a dependency.
**The paradigm shift:**
Traditional: npm install @mui/material gives you a dependency with its own design opinions, release cycle, and breaking changes.
Shadcn approach: npx shadcn-ui@latest add button adds button.tsx to your components/ui/ directory. You own it. Modify it freely. No version conflicts.
**Accessibility via Radix UI:**
Every shadcn component is built on Radix UI primitives designed with accessibility as the primary constraint. Every keyboard interaction (Tab, Escape, Arrow keys), every ARIA role, every focus trap, and every screen reader announcement is implemented correctly. WCAG 2.1 AA compliance without writing a single ARIA attribute.
**Adoption metrics (2025):**
- GitHub stars: 65,000+ (fastest-growing React component collection ever)
- npm CLI downloads: 8M/month
- Used by: Vercel, Linear, Resend, Cal.com, and 500,000+ projects
- State of React 2024: #2 most-used UI component library
**Components shipping:**
Form (React Hook Form + Zod), DataTable (TanStack Table), Calendar, Command Palette, Combobox, DatePicker, Sheet, Dialog, Dropdown, Toast — all with full keyboard navigation and screen reader support.
