Looks like a nice basic set of components ala Bootstrap & DaisyUI. Kinda wish Tailwind would just build these component classes in directly vs encouraging the copypasta of utilities, but maybe I'm not the right customer for Tailwind.
I also thought this is what Tailwind already provided.
Tailwind UI is the component product.
Tailwind doesn’t provide components, they provide classes that map more or less 1:1 with CSS rules. They have a secondary project, TailwindUI (mostly gated behind a paywall), that provides examples of using their classes to build full-fledged components
