shadcn/ui has become the dominant React component approach for modern applications. Rather than installing a component library as a dependency, you copy the component source directly into your project -- giving full ownership and customization without dependency lock-in. Confidence is docs-derived.
The component surface covers a comprehensive set of UI primitives: Button, Input, Dialog, Select, Table, Card, Badge, Tabs, Alert, Toast, Combobox, Calendar, and many more. All are built on accessible Radix UI primitives styled with Tailwind CSS.
shadcn/ui components are local code -- no external platform auth. The CLI (npx shadcn@latest add button) downloads component source. Full ownership means no breaking change risk from upstream library updates.
Operationally, owning the component source means teams can modify accessibility patterns, theming, and behavior without fighting library constraints. The Tailwind-based styling integrates naturally with existing Tailwind codebases. Components bundle only what is used.
Documentation at ui.shadcn.com is excellent and includes component previews, code examples, and customization guides. Developer experience is outstanding -- the combination of Radix accessibility, Tailwind styling, and full code ownership is uniquely valuable.
