React Design Systemfor Agentic Interfaces
Helios UI brings reusable React components, interactive data charts, complete application templates and shared design tokens into one system.
Why Helios UI
You own the source
Copy editable React and Tailwind source with its dependencies. Keep the implementation in your project and change the parts you need.
Built for AI agents
A local MCP server supplies component source, props and semantic tokens so your agent can work with the actual implementation.
Accessible by default
Shared React Aria primitives provide keyboard navigation, focus management and accessible semantics across the library.
Design and code together
Helios branding and recorded foundations connect to reusable examples. The Figma library is maintained separately and stays unchanged here.
Dark mode built in
Semantic tokens resolve light and dark appearances. Change the theme or accent to see the same components adapt.
Data-dense from day one
Interactive chart cards, tables and complete dashboard templates bring real data states and reusable controls together.
Installation
Download the React source archive and install it in a React 19 application. The package includes typed exports, styles, source files and public assets.
npm install ./helios-ui-react-0.1.0.tgz
// Import once from your application entry:
import '@helios-ui/react/styles.css';
