Interesting features are "profile manager", which sounds like an LDAP server and the Mail/Calendar server to replicate Exchange functionality.
I'm still trying to figure out how to use it. I've installed it, added a git-repo, created a Bot, but it does nothing. Also, I don't know how to tell it to do "pod install"[1] before attempting to build the app.

I just want to see Bots work and what is has to offer that my already existing Jenkins CI environment doesn't.
Jenkins is going to have alot more functionality, especially with 3rd party integrations and doing arbitrary work. Jenkins is also an ugly mess than can be painful to setup, especially since most iOS/Mac developers build from Xcode and not the command line. OS X Server gets some ease of use out of only doing running standard Tests, static analysis, and building your project for distribution (they bragged about 1-click downloads from their Bots website to people in your company, but I haven't tried that). Bots integrates with Xcode to give you a nice rundown of how tests ran on multiple devices and OSes.
Can it help manage my current home media server, a headless 2003 Dell running SuSE?
