UX Components: Design System Reference - A reference for UI components across 210 design systems.

by•
UX Components is a practical, open reference for UI components across design systems. Browse by category or through the atomic design hierarchy, compare semantic naming and component states side by side, and dig into a directory of 210 design systems. It also covers universal icons and icon libraries, W3C ARIA patterns (including the ones no system has mapped), a DESIGN.md reference, and an MCP server so agents can pull the same data.

I built this to teach myself how design systems think. Every system names things differently. One calls it a Snackbar, another a Toast. I wanted to see that semantic layer clearly, so I indexed 210 systems, mapped the naming across them, and left the reference open for anyone else asking.
