Headless UI
Headless UI — A clean lightweight pick for Tailwind users who need a small set of unstyled accessible building blocks, but it is less complete than Radix, React Aria, or shadcn/ui for a full application component system.

shadcn/ui
shadcn/ui — My default choice for a new Tailwind/Next.js product because you own the component source code, can modify it freely, and its accessible composable patterns work especially well with AI coding tools.
