Hey guys,
If someone looking for tool to setup autocompile on server i recommend to use https://www.jetbrains.com/teamcity/
They recently released version 2017.2 which allowing to have 100builds for free and run it on 3 agents, which means u can autocompile 50-100 projects (IOS and Android) if more then 100 u will need to remove older projects and run at same time compile for 3 projects. If comparing to Jenkins it is more simplier and clear interface.
what for it is needed https://en.wikipedia.org/wiki/Continuous_integration
