21st

21st is a marketplace and distribution platform for React components styled with Tailwind CSS and shadcn/ui. It functions as a community-driven registry where developers can discover, share, and install reusable interface blocks and visual themes.

The platform features a command line tool that imports specific UI elements and their required dependencies directly into a local development environment. Instead of traditional package management, it uses a source code transfer model to copy raw files into the project codebase for full customization.

The system supports a full lifecycle of component management, including a web-based gallery for previewing variations and a utility for publishing custom-built interface elements to the public registry. It also includes a distribution system for shared visual style configurations and theme extensions.
