For comparison, the one I use is called CapRover, and works great for my small use cases. It's like dokku with a web interface, and can do rebuilds from git webhooks.
Another vote for CapRover, has many addons easy to also add also your docker based apps.
Not a full production system but nice out of the box interface and monitoring.
If it removes its single points of failure it might even turn out to compete with the big guys.
