React Cosmos

React Cosmos is a developer tool and sandbox for building, testing, and iterating React UI components in isolation. It facilitates scalable, high-quality user interface development by providing an elegant interface, component fixture creation and browsing, a playground for component states, debugging support, global search, responsive preview mode, and automation for component testing. It supports static export for deployment and integrates with popular tools like Vite, Webpack, React Native, and Next.js. Built with 100% TypeScript, React Cosmos is highly extensible via a full-stack plugin system and enables creation and publishing of component libraries to enhance productivity and prototyping.
