Zag: Open-source Framework for Building Design System for React, Solid, and Vue

As a developer, you know the pain of building and rebuilding the same components—Tabs, Modals, Menus—over and over again for different frameworks like React, Solid, and Vue. It’s tedious, time-consuming, and often leads to inconsistent or inaccessible UIs.

That’s where Zag comes in—a game-changing open-source framework that lets you "write once, use everywhere". With Zag, you can focus on creating amazing user experiences without worrying about framework-specific quirks or accessibility pitfalls.

What Makes Zag Special?

Zag is not just another library—it’s a smarter way to build design systems. By leveraging finite state machines, Zag models component interactions in a predictable, reusable, and framework-agnostic way. Whether you’re working with React, Solid, Vue, or something else entirely, Zag has got you covered. And the best part? It’s built with accessibility at its core ♿️, so your components work for everyone, right out of the box.

Why Developers Love Zag

Here’s what makes Zag stand out from the crowd:

• Framework-Agnostic: Write your logic once and deploy it across React, Solid, Vue, or any other framework. No more reinventing the wheel.
• Accessibility by Default: Zag handles keyboard navigation, focus management, ARIA roles, and attributes, ensuring your components are WCAG-compliant and inclusive.
• Headless Architecture: Zag doesn’t impose any styles, giving you complete freedom to use Tailwind CSS, styled-components, or plain CSS. Your design, your rules.
• Powered by State Machines: Built on modern Statechart principles, Zag makes complex component behavior predictable, testable, and scalable.
• Reusable Patterns: From Tabs to Modals, Zag provides pre-built, battle-tested implementations of common UI patterns, saving you hours of development time.

How Can Zag Help You?

• Streamline Cross-Framework Development: Share logic seamlessly between frameworks without duplicating effort.
• Build Accessible Apps Faster: Leverage Zag’s built-in accessibility features to create WCAG-compliant interfaces effortlessly.
• Customize Without Limits: Use any styling solution you prefer while maintaining full control over your components’ appearance.
• Scale with Confidence: Predictable state machines make debugging, testing, and extending components a breeze.

Getting Started with Zag

Ready to see Zag in action? Here’s a quick example of how to create an accessible modal using Zag:

import { createModalMachine } from '@zag-js/modal';
import { useMachine } from '@zag-js/react'; // Or @zag-js/vue, @zag-js/solid

function App() {
  const [state, send] = useMachine(createModalMachine());

  return (
    <div>
      <button onClick={() => send('OPEN')}>Open Modal</button>
      {state.matches('open') && (
        <div role="dialog" aria-modal="true">
          <h2>Modal Title</h2>
          <p>This is a fully accessible modal!</p>
          <button onClick={() => send('CLOSE')}>Close</button>
        </div>
      )}
    </div>
  );
}

With just a few lines of code, you’ve created a modal that works across frameworks and meets accessibility standards.
