ReUI is a free, open-source React component library for the shadcn/ui ecosystem, developed by Keenthemes. It provides more than 1,000 copy-and-own registry examples across 71 categories, presented in realistic dashboard layouts rather than isolated demos, including data grids, filters, timelines, steppers, trees, calendars, kanban boards, and other interface blocks. The components are composed from shadcn/ui primitives and Tailwind CSS, with 19 custom in-house component types. Its Data Grid uses TanStack Table and virtualization and supports features such as drag-and-drop, pinning, resizing, and infinite scrolling. The in-house components have both Radix UI and Base UI versions and are distributed as TypeScript source through the registry rather than as an npm package, allowing the source to be copied into a React project. ReUI is released under the MIT License.

ThreeUI is a free, open-source, login-free catalog and React component library for interactive Three.js, WebGL, shader, and UI components. Its Community edition provides browsing, search, themes, responsive layouts, live renderers, controls, variant pickers, source-code tabs, and complete Community component source code, while excluding Pro and Beta components and authentication, checkout, and Pro implementation source. The public library can be installed from npm as @designcodeio/threeui and imported as React components with shared styles through the package root or component subpaths, or run locally with Vite from the repository. Components that render full HTML documents require runtime assets to be copied into the host application's public directory. Application code and Community component code are MIT licensed; bundled fonts use the SIL Open Font License 1.1 and bundled Three.js runtime files use the MIT license.

React is a JavaScript library for building web and native user interfaces. It uses declarative views that update the appropriate components when application data changes, and lets developers compose encapsulated, state-managing components into larger interfaces. React code can use JSX, an HTML-like syntax for defining interface elements, although JSX is optional. The library is designed for gradual adoption, can render on the server with Node, and supports mobile applications through React Native. Its core repository is developed openly on GitHub under the MIT license.

shadcn/ui is an open-source collection of accessible UI components and a code distribution platform for building custom component libraries. It distributes component source code directly into consuming projects, where developers can customize, extend, and build on the components across supported web frameworks. Documentation is available at ui.shadcn.com/docs, and the project is licensed under the MIT license.
