Unstyled, accessible UI components (React and Vue) that you style yourself, often with Tailwind CSS.
The short answer
Choose downshift if you need…
- React developers building a custom autocomplete or search-as-you-type input
- Teams that need a select or combobox that meets WAI-ARIA accessibility patterns
- Developers who want full control over how the dropdown looks
- Projects building multi-select inputs with tags, using useTagGroup
Choose Headless UI if you need…
- React or Vue developers building custom-designed interfaces
- Teams already using Tailwind CSS who want accessible widgets that match their styling
- Projects that need keyboard and screen reader support without writing it from scratch

What each one is
downshift
Downshift is a JavaScript library for React that handles the behavior and state of dropdown-style inputs such as autocomplete boxes, comboboxes and select menus. You supply the markup and styling, and it supplies the keyboard handling, highlighting and accessibility attributes that follow WAI-ARIA patterns. The README recommends its hooks, useSelect, useCombobox and useTagGroup, over the older Downshift render-prop component.
Headless UI
Headless UI is a set of interface building blocks such as menus, dialogs and similar widgets for React and Vue. The components come with behavior and accessibility built in but no visual styling, so you control the look with your own CSS, typically Tailwind CSS. It is used by developers who want accessible components without adopting a fixed design system.
Best for

Strengths
downshift
- Accessibility is built in, following the ARIA combobox pattern as stated in the README
- Small API surface and flexible rendering, since you control all of the markup
- Actively maintained with a documented migration guide for version 7
Headless UI
- Components are unstyled, so they fit into any visual design
- The README describes the components as fully accessible
- Maintained by the Tailwind Labs team and published under the MIT license
Not ideal for
downshift
- People who want a ready-made styled component out of the box; the README says you render everything yourself
- Projects not using React or Preact, since the library is built for those frameworks
- Teams needing the older Downshift component for new work, since the README says the hooks are recommended and the component will eventually be removed
Headless UI
- Anyone who wants ready-made, good-looking components out of the box, since the README says the components are completely unstyled
- Projects not using React or Vue, since the README lists only those two packages
- Beginners with no web development background, since the components require writing your own markup and styles
Trade-offs
downshift
- You must write the UI yourself, which means more code than a prebuilt component
- The README is truncated here, so detailed hook options are only available in the linked docs
- Downshift is recommended as hooks, so the older component API is not the path forward
Headless UI
- Requires you to write your own styling, so it is not a quick visual solution
- The README lists only React and Vue packages and does not describe other frameworks
- Insiders builds do not follow semver, so their APIs may change
