Storybook for Marionette.js is a UI development environment for your Marionette.js components. With it, you can visualize different states of your UI components and develop them interactively.
Storybook runs outside of your app. So you can develop UI components in isolation without worrying about app specific dependencies and requirements.
cd my-app

Storybook also comes with a lot of addons and a great API to customize as you wish. You can also build a static version of your storybook and deploy it anywhere you want.
