Looks interesting. But, a similar solution exists with a similar name called PageKite (https://pagekite.net/). They do not deploy your application code to the cloud. With PageKite you run your environment locally and then create a tunnel from a public address to your local environment.

I think the only benefit to Kite is if you want your development application to be running from a public address for a long time.

The PageKite approach allows you to have whatever web environment you want and to bring it up/down at will. I have used PageKite for over a year and it has worked very well. It also seems safer, since I wouldn't want to deploy my development changes to a public web site with some unintended security flaw.
