Seems that, unlike Sidekiq, this starts as a heavily commercial solution, and it shows. Landing page has a pretty big "Buy Pro" call-to-action button. Features like support for notifying slack/etc I'd expect to be present in a free version. Open source feels more of an afterthought. I don't feel comfortable using even the free version, simply because if the project fails financially, it is likely to be dropped altogether.
