ThreeUI

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.

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.

Three.js is an open-source JavaScript 3D library developed in the mrdoob/three.js project for assembling and rendering procedural scenes in browser applications, including Fable 51 Worlds, Human Atlas, browser FPS worlds, CAD workspaces, and physics games. It creates scenes containing cameras, geometry, materials, meshes, and animations, with WebGL and WebGPU renderers and SVG and CSS3D renderers available as addons. Its official site and repository provide documentation, examples, tools, an editor, community resources, and a JavaScript module distribution.

Canvas UI is an open-source, framework-agnostic library of creative UI components that render canvas and WebGL effects over live, interactive HTML. Its components use the experimental HTML-in-canvas API to read and redraw the DOM as a texture while preserving selectable text and clickable links; where that API is unavailable, they fall back to WebGL overlays. The library includes fluid simulations, shader effects, 3D scenes, distortion, particles, glass, fire, retro, and glitch effects, including Liquid, Ripple, Blaze, Glass, VHS, Shatter, and Decrypt Reveal. Each component is implemented as a plain TypeScript and WebGL engine with thin wrappers for React, Solid, Preact, Vue, Svelte, and vanilla JavaScript. Components are copied into an application through a shadcn-compatible registry rather than installed as a conventional dependency, and provide typed props with default configuration. The registry is MCP-ready for AI-assisted component discovery and installation. HTML-in-canvas effects require Chrome with the relevant flag or an origin-trial token; other environments use the WebGL-overlay fallback, while the library’s 3D effect components work without that flag. The project includes the component source, documentation site, demos, and registry builder, and is distributed under the MIT license with the Commons Clause, which restricts selling the library itself.
