21st.dev
A community registry for React components
21st.dev is a directory where design engineers publish React components, templates and themes for shadcn/ui. Over 12,000 components such as heroes, pricing tables, buttons or dialogs can be previewed live and pulled into a project through the shadcn CLI or as a ready-made prompt for coding agents. The code lands entirely in your own repository, with no extra package.
Why it made the cut- Over 12,000 components with live previews
- Install via the shadcn CLI or an agent prompt
- Component code also available via MCP
