## What it is
Ark UI is a headless, unstyled component library providing 45+ accessible UI primitives built on Zag.js finite state machines. It offers identical component APIs across React, Solid, Vue, and Svelte for building custom design systems.

## Use cases
- build a custom design system with accessible components
- headless dialog, accordion, and slider components for React
- unstyled UI primitives I can style with Tailwind
- same component API across Vue and React projects
- WCAG-compliant components with keyboard and screen reader support
- replace a styled component library without fighting default styles

## When to choose
- you want full styling control with accessible behavior handled for you
- you maintain design systems across multiple JavaScript frameworks
- you need predictable, testable component logic backed by state machines

## When to avoid
- you want pre-styled, ready-to-use components out of the box
- your project uses a framework outside React, Solid, Vue, or Svelte
- you need a complete themable design system rather than primitives
