Headless UI is an open-source library from Tailwind Labs, the team behind Tailwind CSS, that provides unstyled, accessible interface components such as menus, dialogs, tabs and listboxes for React and Vue. It runs entirely in the site's front-end code and does not contact a third-party server or set tracking cookies.
