Uiverse
The largest community-built library of open-source UI elements — 7,400+ buttons, loaders, cards, forms and toggles you copy as HTML/CSS, Tailwind, React or Figma, 100% free under MIT.
What is Uiverse?
Uiverse is the world's largest community-driven library of open-source UI elements. Designers and developers (370,000+ contributors) continuously submit buttons, cards, loaders, switches, checkboxes, inputs, toggles and modals, and every element can be copied instantly as HTML/CSS, Tailwind, React or Figma. Fine-tune colors, size and speed in the live playground before copying, browse curated collections such as 1,200+ loading indicators, and use everything free for personal and commercial projects under the MIT license. The whole library is also published as the Uiverse Galaxy GitHub repository, and an MCP server lets AI coding tools such as Claude Code, Cursor and Codex pull components by natural language with no API key.
