Radian UI

About Radian UI

Radian UI is an open-source component library that provides production-ready React components alongside a Figma UI Kit and design system. The React library includes over 50 pre-styled components built with Tailwind CSS, distributed for copy-and-paste use, with properties designed for customization. The Figma UI Kit includes over 2000 components and 1000 assets built with auto layout and Figma slots, covering text styles, color styles, variables (device, theme colors, color primitives, font family, radius, spacing), icon assets, and effect styles such as shadows and focus rings.

The product targets designers and developers, including startups and agencies, working on interface design and front-end implementation. It supports design-to-code workflows by using shared semantic tokens and variables between the Figma design files and the code components, and includes documentation, UI blocks, and animations alongside the component set. Individual component categories listed include checkboxes, inputs, buttons, dropdown menus, tabs, badges, accordions, alerts, avatars, banners, breadcrumbs, calendars, code areas, color pickers, credit card inputs, date pickers, and dialogs.

The page also references compatibility with AI coding assistants, describing the components and blocks as usable via prompts for AI-assisted development.
