This is an extended version the React Storybook[0] we launched few weeks ago. With Storybooks.io, you can access your storybooks right next to any GitHub pull request. Then, it's easy to review UI features without running a demo app.
We are launching Storybooks.io in few weeks, really looking forward your comments and ideas.
