Coss

A UI component library built on top of Base UI that provides pre-built interface components to help build consistent user interfaces without creating common elements from scratch. It is for developers and designers in business teams who build web products and need reusable components. It is delivered as an open-source library with a catalog of components such as dialogs, forms, navigation and data display elements that can be integrated into codebases and used with AI-assisted workflows.
