About

coss ui is a new, modern UI component library built on top of Base UI and styled with Tailwind CSS. It offers a collection of beautifully designed, accessible, and composable components for React applications, following a 'copy-paste' ethos similar to shadcn/ui, allowing developers full ownership and customization. The library provides a layered approach with UI primitives (unstyled, accessible building blocks), particles (pre-assembled components), and atoms (API-enhanced components for integrations). It is designed for both humans and AI, ensuring clarity and predictability, and is part of the COSS (Commercial Open Source Software) philosophy, aiming for sustainable open-source development. coss ui is being progressively adopted by Cal.com.

Design Review

The design aesthetics of coss ui are described as 'beautifully designed' and 'modern,' aiming for 'dense UIs' with a 'consistent design system.' The reliance on Tailwind CSS suggests a highly customizable and utility-first approach to styling, allowing developers to craft precise visual experiences. Usability is a core strength, with a strong emphasis on accessibility, keyboard navigation, and focus management, all handled by the underlying Base UI primitives. The 'copy-paste' model ensures developers have full control, fostering deep customization. The layered approach (primitives, particles, atoms) enhances developer usability by offering varying levels of abstraction, from barebones building blocks to API-integrated solutions. The 'Built for Humans and AI' principle implies a clear, predictable component structure that benefits both human developers and automated tools, contributing to overall system clarity and maintainability.
