uiverse.io

A community library of open-source UI components — buttons, cards, loaders, toggles, checkboxes — all in pure CSS or Tailwind, with copy-paste code for each element and no JavaScript required.

Why it is useful

Saves hours of CSS micro-animation and interaction work by providing community-tested implementations of common UI elements. The quality ranges from practical to highly creative, and everything has copy-pasteable code. Particularly useful for adding polish to utility projects where building custom animation CSS from scratch isn't worth the time. All components are free and open source.
