Etsy uses GitHub Enterprise for code reviews of code committed to their on-premise git repositories. They have over 350 Linux virtual machines called "The Bobs" that are used to build and test code. Etsy also has 25 Mac Minis that are used to build, test, and run linting on their mobile Android and iOS code using an automated process with Chef. The summary describes Etsy's implementation of continuous integration for mobile apps using GitHub, Linux VMs, Mac Minis, and automation with Chef to improve testing and visibility of their code.
