Show HN: HyperDev – dev playground for full-stack web apps by Fog Creek

Hey HN, we're excited to show you our beta of HyperDev, a developer playground for quickly building full-stack web apps. I'll try and respond to comments as I can.

Is this just free while in beta, or will it be free/have a free tier afterwards?

Is this intended just for prototyping/dev or full hosting of production apps?

Will there be options to have code stored in Kiln/GitHub/whatever?

Which server side technologies are currently supported and/or planned?

Custom domains?
