React Cosmos - Dev Tool for React

Dev tool for creating reusable React components.

Cosmos is a dev tool first, made to improve all components, big and small, not just the stateless UI bits. The fixture and proxy architecture double as an automated testing utility, providing a complete solution for developing robust and reusable components. Cosmos also makes it easy to create a living style guide, but it's a secondary goal and you might get more value from alternatives if this is your chief concern.
