This was amazing back in the day. I'm much more impressed either digitalocean's App stuff. It just hooks right up to github, autoconfigures, and my devops workflow is reduced to `git push`
Heroku's got effectively the same and with review apps it's a great experience.
Heroku was early in the integration to GitHub. It was surprising to see how many apps were "broken" and "unable to deploy" with the security incident a bit ago because they did know how to git push they'd only connected their apps to GitHub.
