Review apps on Heroku

Has anyone used the new Heroku feature to automatically deploy “Review Apps” for PRs on Github?

Looks really cool, but I’m curious if folks have any experience using it yet.

@christoomey tried to get this working for us, but I think we haven’t made it happen yet.

At work we use fourchette which I believe this got it’s inspiration from. It works most of the time, but it tends to be buggy. Most of the time it’s amazing. I love the workflow. We create PR’s and a staging site is up within a few minutes. It’s super helpful and is one of my favorite things.
