Build scalable design systems with unstyled, accessible UI components

Overview

Ark UI is a headless component library that provides the foundation for building high-quality, accessible design systems and web applications. Built on top of Zag.js state machines, Ark UI delivers robust, framework-agnostic component logic with perfect parity across React, Solid, Vue, and Svelte.

Why Ark UI?

• ** Completely Unstyled** - Zero styling opinions. Bring your own styles with CSS-in-JS, Tailwind, vanilla CSS, or any styling solution
• ♿️ Accessibility First - WCAG compliant components tested with real assistive technologies out of the box
• ** State Machine Powered** - Predictable, testable behavior powered by Zag.js finite state machines
• ** Multi-Framework** - Same API across React, Solid, Vue, and Svelte - write once, use everywhere
• ** Truly Composable** - Granular component primitives that work together seamlessly
• ⚡️ Production Ready - Battle-tested in products like Chakra UI, used by teams at OVHCloud, PluralSight, and more
• ** Type-Safe** - Fully typed with TypeScript for exceptional developer experience

Installation

Choose your framework and install the corresponding package:

# React
npm install @ark-ui/react

# Solid
npm install @ark-ui/solid

# Vue
npm install @ark-ui/vue

# Svelte
npm install @ark-ui/svelte

Quick Start

Here's a simple example showing how consistent the API is across frameworks:

React

import { Dialog } from '@ark-ui/react/dialog'

export const MyDialog = () => (
  <Dialog.Root>
    <Dialog.Trigger>Open Dialog</Dialog.Trigger>
    <Dialog.Backdrop />
    <Dialog.Positioner>
      <Dialog.Content>
        <Dialog.Title>Dialog Title</Dialog.Title>
        <Dialog.Description>Dialog description</Dialog.Description>
        <Dialog.CloseTrigger>Close</Dialog.CloseTrigger>
      </Dialog.Content>
    </Dialog.Positioner>
  </Dialog.Root>
)

Vue

<script setup lang="ts">
import { Dialog } from '@ark-ui/vue/dialog'
</script>

<template>
  <Dialog.Root>
    <Dialog.Trigger>Open Dialog</Dialog.Trigger>
    <Dialog.Backdrop />
    <Dialog.Positioner>
      <Dialog.Content>
        <Dialog.Title>Dialog Title</Dialog.Title>
        <Dialog.Description>Dialog description</Dialog.Description>
        <Dialog.CloseTrigger>Close</Dialog.CloseTrigger>
      </Dialog.Content>
    </Dialog.Positioner>
  </Dialog.Root>
</template>

Solid

import { Dialog } from '@ark-ui/solid/dialog'

export const MyDialog = () => (
  <Dialog.Root>
    <Dialog.Trigger>Open Dialog</Dialog.Trigger>
    <Dialog.Backdrop />
    <Dialog.Positioner>
      <Dialog.Content>
        <Dialog.Title>Dialog Title</Dialog.Title>
        <Dialog.Description>Dialog description</Dialog.Description>
        <Dialog.CloseTrigger>Close</Dialog.CloseTrigger>
      </Dialog.Content>
    </Dialog.Positioner>
  </Dialog.Root>
)

Svelte

<script lang="ts">
  import { Dialog } from '@ark-ui/svelte/dialog'
</script>

<Dialog.Root>
  <Dialog.Trigger>Open Dialog</Dialog.Trigger>
  <Dialog.Backdrop />
  <Dialog.Positioner>
    <Dialog.Content>
      <Dialog.Title>Dialog Title</Dialog.Title>
      <Dialog.Description>Dialog description</Dialog.Description>
      <Dialog.CloseTrigger>Close</Dialog.CloseTrigger>
    </Dialog.Content>
  </Dialog.Positioner>
</Dialog.Root>

Features

Zero-Styling Freedom

Every component is completely unstyled, giving you total control over your design. Use any styling solution:

// Tailwind CSS
<Dialog.Trigger className="px-4 py-2 bg-blue-500 rounded">Open</Dialog.Trigger>

// CSS-in-JS
<Dialog.Trigger css={{ padding: '8px 16px', background: 'blue' }}>Open</Dialog.Trigger>

// Vanilla CSS
<Dialog.Trigger className="my-button">Open</Dialog.Trigger>

Accessibility Built-In

All components follow WAI-ARIA design patterns and are tested with screen readers:

• ✅ Proper ARIA attributes and roles
• ✅ Keyboard navigation support
• ✅ Focus management
• ✅ Screen reader announcements
• ✅ RTL support

State Machine Architecture

Powered by Zag.js, each component uses finite state machines for predictable behavior:

• Type-safe state transitions
• Easier to test and debug
• Fewer edge cases and bugs
• Visualizable component logic

Framework Parity

Maintain a single design system across multiple frameworks without rewriting component logic:

// Same API, same behavior, different frameworks
const packages = ['@ark-ui/react', '@ark-ui/solid', '@ark-ui/vue', '@ark-ui/svelte']
