About git.kontain.me - what if I'd like to setup my own copy of such a service and would like it to work with a non-public git repo, how to pass credentials? Since you support only cloning over https (btw, why not over ssh as well?) - one could use an URL of format user:pass@host:port/path/to/repo, would that work?
I have yet to receive any commercial interest in any of these tools :)
