You can use 21st to discover, preview, and install pre-built React components, shadcn themes, and full UI templates created by design engineers. Instead of installing heavy dependencies, you can copy prompts directly into AI coding tools like Cursor, Claude Code, or Lovable to insert clean code into your repository. You can also install components using standard shadcn CLI commands, bookmark favorites into custom team lists, publish your own UI creations, and access full application templates to quickly build modern web interfaces.
