A minimal, constraint-driven UI toolkit that enhances HTML instead of replacing it. Built for developers who value performance, simplicity, and the web platform.

• 🚀 Tiny Bundle: ~5KB JS + ~6KB CSS for all components
• ⚡ Zero Re-renders: No state, direct DOM reactions via native commandFor (with fallback)
• 🌐 Platform-Native: Uses <dialog>, form validation, CSS custom properties
• 📦 Tree-Shakeable: Import only what you use
• 🎨 Beautiful by Default: Carefully crafted design system

pnpm add pui

import { Button, Dialog, Input } from 'pui';

function App() {
  return (
    <>
      <Button variant="outline" size="lg">
        Click me
      </Button>

      <Dialog>
        <Dialog.Trigger>
          <Button>Open Dialog</Button>
        </Dialog.Trigger>
        <Dialog.Content>
          <h2>Hello World</h2>
          <Input placeholder="Type something..." />
        </Dialog.Content>
      </Dialog>
    </>
  );
