Wingo UI is a React 19 + Tailwind CSS v4 library with 226 components and 95 blocks that install as source code, shadcn style. Every component is animated, configurable through props, works in light and dark, and is built mobile first: bottom sheets on phones, 44px touch targets, swipe actions with a visible fallback. A CLI adds items with their dependencies, and an MCP server lets Claude Code, Cursor and other agents search the library and follow its design rules. Many items are free.
