#What is addcn?

addcn is a lightweight, developer-focused registry hosting service that lets you build and distribute custom shadcn/ui components as a personal, shareable registry. It's designed for React developers using shadcn/ui who want to go beyond local copies—allowing teams or the community to install your components directly with the shadcn CLI. The core value lies in simplifying component reuse and distribution without publishing to npm or maintaining a full package: just claim a username, add your components, and share a URL. Ideal for collaborative design systems, internal component libraries, tutorial setups, or showcasing reusable UI blocks in the shadcn/ui ecosystem—works seamlessly with Next.js, Vite, Tailwind CSS, and any shadcn/ui-supported stack.

#Features ⚡

• Personal Registry Hosting: Claim a username and host your components at https://addcn.dev/r/your-username/.

• shadcn/ui CLI Compatibility: Install any component with a single command like npx shadcn@latest add https://addcn.dev/r/username/data-table.

• Easy Component Sharing: Share your registry URL with teammates or publicly for instant access and installation.

• Automatic Dependency Handling: CLI fetches registry info, installs required deps, and places components in components/ui/.

• Simple Setup Flow: Minimal steps to claim, build, and expose your custom components.

• Public or Team-Focused: Share privately with your team or open it to the world for community contributions.
