Catalog

With Catalog you combine design documentation with real, live components in one single place, making collaboration between designers and developers seamless. We believe that maintaining a style guide should require as little extra work as possible. That's why we built Catalog with a focus on simplicity: authoring feels natural for designers and integration is painless for developers. Catalog makes creating and maintaining a style guide as simple as editing plain text files with your favorite editor. Using Markdown formatting allows you to write gorgeous content using an easy-to-learn syntax. Catalog is designed from the ground up to put your design system into the right light. The clean and simple design works beautifully across devices and screen sizes. Catalog is open source and free to use, making it possible for you to add, maintain, or replace it depending on your changing requirements.
