## What it is
Headless UI is a set of completely unstyled, fully accessible UI components for React and Vue, designed to pair with Tailwind CSS. It provides behavior, state management, and keyboard/ARIA accessibility for components like dialogs, popovers, menus, and comboboxes while leaving styling entirely to the developer.

## Use cases
- build accessible dropdown menus in React
- unstyled dialog and modal components for Vue
- accessible combobox with keyboard navigation
- style my own Tailwind components without writing ARIA logic
- headless popover for navigation menus
- accessible tabs and switches without opinionated styling

## When to choose
- you use Tailwind CSS and want full styling control
- you need WAI-ARIA-compliant accessible components without design opinions
- you work in React or Vue and want battle-tested headless primitives

## When to avoid
- you want pre-styled, ready-made component designs
- you use a framework other than React or Vue
- you need a full design system rather than individual primitives
