I feel as though this is one step above just a web page with an email box. Aside from listing a suite of popular OSS, you haven't explained what this app does. Is it similar to Panamax in that it offers you a UI, but only for one box / Flynn or Deis which is trying to create an open source Heroku / something completely different?
VirtKick is like DigitalOcean or Linode - they are focused on machines (and containers, that you think of as machines). You install it on your Linux desktop (for localhost hacking), or home or dedicated server (for something more).
Will try to express it a little bit better. Thanks for your feedback.
