That's what has been the deciding part for us in the end. While Gogs is super lightweight, Gitlab is so feature rich, stable and user focused, that it's the only piece of Ruby that's running in our stack. We were right in the decision phase for a CI and had already set up a Jenkins machine when Gitlab integrated their CI which has been super simple, reliable and well integrated so far, no comparison to the monster that Jenkins is. Recent work on performance has been stellar, setup was quick, including backups, and upgrades have been super painless, they really got the important parts nailed down. Can totally recommend it, and it's really got the traction to both catch up with Github and also offer unique features. The pull/merge request workflow isn't as refined and better code review support would be high on my wishlist, but overall it has been a great choice so far with little regrets.
