Headless UI

Introduction

Headless UI is an open-source set of components from Tailwind Labs focused on getting interaction behavior and accessibility right: it provides only behavior and logic, not visual styles, so you can customize it with any CSS or design system.

Core features

• Supports React and Vue, and integrates seamlessly with Tailwind CSS
• Automatically manages keyboard interactions, focus control, and ARIA attributes to improve accessibility
• Provides reusable primitives such as menus, dropdowns, dialogs, switches, and listboxes

Use cases & target users

Suitable for frontend engineers, design system maintainers, and product teams that need highly customized UIs. Ideal for building design systems or accessible component libraries, or for replacing the behavior layer in existing projects while keeping custom styles.

Key benefits

• Highly customizable: unstyled (headless), appearance is fully under your control
• Accessibility-first: built-in keyboard and screen reader support reduces accessibility implementation costs
• Easy to integrate & open source: well-documented, lightweight, and compatible with existing stacks, making it easy to maintain and extend
