shadcn/ui

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.

audiocn is a React audio UI component library and shadcn registry for level meters, visualizers, waveforms, faders, knobs, channel strips, mixers, players, sound pads, and audio-device controls. Components are copied into an application with the shadcn CLI rather than installed as a package, allowing their source to be modified. The project includes Web Audio hooks for microphones, system or tab audio, audio analysis, mixer state, playback, sound effects, waveform data, and device selection; components can also receive data from another audio engine. It is built with Base UI and Tailwind CSS, uses shadcn-compatible theme variables, and includes keyboard controls, ARIA roles, and reduced-motion support. The repository contains the documentation site, registry source, component source, audio core, examples, and tests, and is licensed 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.

Moumen Lab is a React component registry for interface components such as menus, OTP inputs, upload staging, command palettes, and draggable reorderable lists. Components are distributed in the shadcn registry format and installed as source code with the `moumenlab` CLI or shadcn CLI, so no runtime package is required. The components use Tailwind CSS with shared `lab-theme` tokens and motion-based animations that are interruptible, layout-aware, and reduced-motion aware. The repository includes live showcases, component blueprints, source files, registry metadata, and a monorepo-based CLI; it targets React 19, Tailwind CSS v4, Node.js 18+ for installation, and is licensed under MIT.

OpenShaders is an open-source platform and registry for discovering, creating, publishing, and using shader code in websites. It is being built around a collection of WebGL and WebGPU shaders, a live editor for creating and collaborating on shaders, and ready-to-use React components and JavaScript modules, including a shadcn registry for installing shaders from a terminal. The platform is hosted at openshaders.com and is released under the MIT license; its full experience is still under development, while users can claim usernames, generate shaders, explore existing work, and copy shader code.
