Every package React Cosmos depends on, ranked by repo health score.

React Cosmos is a component development sandbox: instead of building and testing UI components inside a full application (with all its routing, state, and data dependencies), you write small "fixtures" that render a component in isolation with specific props and mock data, then browse and interact with every fixture through a dedicated UI.

The project is a monorepo of focused packages rather than one monolithic tool — `react-cosmos-core` and `react-cosmos-renderer` handle the shared fixture-rendering logic, `react-cosmos-dom` and `react-cosmos-native` provide platform-specific rendering for web and React Native, and separate plugin packages (`react-cosmos-plugin-vite`, `-webpack`, `-boolean-input`, `-open-fixture`) extend the core with bundler support and UI controls rather than baking every feature into the core.

MIT licensed and actively maintained, React Cosmos works with both Vite and Webpack projects, making it a build-tool-agnostic alternative for teams that want an isolated component workshop without adopting a specific bundler's ecosystem.
