Ark UI

Headless component library for building accessible design systems in React/Vue/Solid.

Overview

Ark UI is a headless component library providing 45+ accessible, unstyled UI components designed to work across multiple JavaScript frameworks including React, Solid, Vue, and Svelte. Built on Zag.js and powered by finite state machines, it enables developers to build reusable, scalable design systems without fighting default styles.

The library emphasizes true framework agnosticism—the same API works across all supported frameworks. Components come with WAI-ARIA patterns, keyboard navigation, and screen reader support built in, ensuring accessibility by default. Developers bring their own styling approach, whether that's Panda, Tailwind, CSS-in-JS, or plain stylesheets.

Ark UI is maintained by the team behind Chakra UI and is licensed under the MIT license. It's used by organizations ranging from startups to enterprises, including Chakra UI, Park UI, and various design systems.
