A similar amazing project in my opinion is iohyve. It has a fairly large portion of what you need to become a vserver provider in one command, easy to use:
Also vm-bhyve, which I've been happily using since 2015. Also amazing, also dead simple.

It is nice that there are multiple wrappers around bhyve - competition is good, and it shows a healthy community.
