Have recently rebuilt CI systems at work, and took a look at Concourse alongside Jenkins, Buildbot and Gitlab. Seems like not so many people have mentioned gitlab on this thread, but in my experience it combines all the benefits of Concourse (pipeline-driven workflows, passing forward build artifacts, config in source control) with a much simpler architecture. Concourse looks so complex and has so many moving pieces to learn - BOSH, fly, etc...

Gitlab is just a rails app and then has a go-based runner to do the CI work. Omnibus packages make installation easy. They even have some autoscaling stuff for the runners using docker engine there which I still think needs some work for my use case but for may others is ready to go and looks awesome.

CI covers so many use cases and so there is lots of room for different alternatives, but make sure to check out gitlab if you're looking for the simplest and most flexible CI system I've yet to see :)

Thanks for mentioning GitLab, glad to hear you like it!

We just officially released the autoscaling runner in https://about.gitlab.com/2016/03/29/gitlab-runner-1-1-releas... Please let me know what we can do to improve it for your use case.
