shadcn/ui

Component foundation + registry

FreeCore design stackui.shadcn.com

What it is

50+ accessible components built on Radix (now Base UI by default) and Tailwind, distributed as source copied into your repo rather than an npm dependency. Also ships Blocks, Charts, a Themes browser, and the registry protocol. 121k stars.

Why it earns a slot

This is already your project. The reason it matters strategically: React Bits, 21st.dev, Magic UI, Kokonut and ElevenLabs UI all publish into its registry, so wiring the official shadcn MCP once gives Claude an install path into every one of them.

Getting started

npx shadcn@latest mcp init --client claude
