by coss
Open-source UI components built with Base UI and Tailwind for refined product interfaces.

Design notes
coss ui is a modern component system from the team behind Cal.com. Built on Base UI primitives, it combines accessible interaction foundations with a distinctive component treatment and a practical code-first workflow.
The library is a strong reference for teams looking to develop their own visual identity on top of accessible, composable primitives.
