Uiverse

Community archive of ~4,400 MIT-licensed CSS and Tailwind UI snippets

Tier A · StrongComponent LibraryGalleryAsset Packuiverse.io

Uiverse is a community-submitted library of single-element UI snippets written in plain HTML with either vanilla CSS or Tailwind classes. Every element is MIT licensed and copied straight out of the browser; the categories are Buttons, Cards, Loaders, Toggle switches, Inputs, Forms, Checkboxes, Patterns, Radio buttons, Tooltips and Notifications. The open-source mirror lives in the uiverse-io/galaxy repo, where each element is one self-contained HTML file. It is for developers who want a decorative, animated one-off element rather than a coherent design system.

For an agent

Treat this as a snippet quarry, not a library: there is no package, no props API, no a11y contract, and quality swings wildly between authors, so lift one element (a loader, a fancy toggle, a gradient button) and rewrite it against your own tokens. uiverse.io itself returns 403 to crawlers and CLI fetchers, so pull code from the github.com/uiverse-io/galaxy mirror instead — one self-contained HTML file per element under Buttons/, Cards/, loaders/ and so on. Do not use it where keyboard, focus, or ARIA behaviour matters; pair it with shadcn/ui or Radix for anything interactive.

Why it is here. It is the largest open, MIT-licensed pool of pure-CSS UI elements on the web, and the one place to find an animated micro-detail nobody has written a React component for. Its weakness — no API, no accessibility — is exactly why it belongs in the index as a snippet source rather than a dependency.
