Core developer of Dokku here: Dokku is very much a single-server solution. Though I have played with actual implementations (that work!), there are no plans to make the core support multi-hosts. Dokku also currently has no admin dashboard (there hasn't been a need, though this is something I'd like to address) and doesn't need as many requirements (you can install it via a deb package). It's written in bash, which can be a turnoff for whatever reason. paz looks like it depends upon multiple services, which may be difficult to setup or maintain, but is solution to a completely different problem. I will say, Paz looks quite nice.
