Mergify is one of, if not the most powerful automated merging services available right now. With their extensive configurability every scenario and idea that we've had to improve our code review & merging processes has been possible. Their customer support through their community Slack channel is incredibly fast and responding to questions which has made using Mergify a joy to use.
The experience on Contra keeps getting better as they release new features. It's hard *not* to love a platform that lets you do independent work with others and *not* charge a commission.
