About UI Arc

UI Arc is an innovative open-source library of React components designed for developers who want polished, ready-to-use UI elements with built-in motion. Its core library is freely available under the MIT license, and it integrates seamlessly with the shadcn CLI, allowing developers to embed and modify components directly within their projects. Each component is accompanied by comprehensive Markdown documentation, llms.txt files, and an MCP server, enabling intelligent selection and installation via Claude Code or Cursor, streamlining the development process. The Pro version adds showpiece motion components and full app screens, with new components shipped daily, making UI Arc a dynamic resource for modern web development. Its open-source nature encourages customization, flexibility, and rapid prototyping, making it ideal for developers seeking a polished, motion-rich UI toolkit that evolves quickly.
