Headless UI is an unstyled, fully accessible component library from the Tailwind CSS team, providing interactive primitives (dropdowns, modals, menus) with all behavior and accessibility handled but no visual styling imposed — meant to be paired with Tailwind CSS. Our engine detects it through 1 script pattern and 1 HTML pattern tied to its ARIA-attribute conventions on interactive elements, which is a lighter signal than fully-styled libraries since there's no distinctive CSS class prefix to match against.
