> GitLab is so much more - it encompasses the full DevOps Lifecycle in a single application

That's what I meant by "integrated services already possible with Github". I guess you are familiar with Github Marketplace.

I don't mean to offend GitLab, it's a great service, I just mean that it could be much more if it worked on low level things too, like storage of issues as git objects, or federated instances. These are hard problems that won't make GitLab easy sell to a manager but definitely interesting things that would get developers attention.
