Buddybuild vs Jenkins

A continuous integration, continuous deployment, and user feedback platform for iOS development teams.
In a nutshell Jenkins CI is the leading open-source continuous integration server. Built with Java, it provides 1009 plugins to support building and testing virtually any project.

2018 - Apple buys continuous integration service Buddybuild. Beware Jenkins !

Apple has acquired Buddybuild, an app tools startup that describes itself as “mobile iteration platform” focused on continuous integration and debugging tools — essentially giving an app development team a simple workflow for iterating and pushing their apps out into the world through GitHub, BitBucket or GitLab. As part of the acquisition, Buddybuild will be rolled into Xcode, Apple’s suite of development tools for iOS, macOS, watchOS and tvOS, although Apple and Buddybuild have not given a specific timeline of when that will happen.
