@markhorgan Yes, that's part of the story. It currently supports Babel, CoffeeScript, Jade, Less, Sass and Stylus.
There's more to it than that though. It also does Live Share, which gives you a public URL that mirrors your site exactly as it is on your local machine. If you make a change then the Live Share is automatically updated without needing a browser refresh.
Deployment is pretty sweet too. Deploys with Pingy will be free and include SSL and HTTP/2. Even if you cancel the Pingy subscription, your site will still stay online. It's important to me that nobody is locked in. :-)
@DaveJ You can preview the prototype instantly in Sketch or on a device - no need to upload to a web-app first. No monthly subscription. And finally the prototype adapts to any screen size.
