Glad I read this before we plunged into EE. It will please the Trello lovers.
We have been evaluating several tools and the vision Gitlab is demonstrating with their idea to production is near perfectly aligned.
Once https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/10109 lands it'll be an amazing place to host projects and specifically monorepos that produce multiple containers.
Has a Trello-like work board, good project management and - most importantly - a sane and highly optimized workflow that works very well for a number of large companies and open source projects.
I'll just link to another comment of mine: https://news.ycombinator.com/item?id=13939608
Happy to answer any questions! (give it a few hours though)
Of course gitlab's problems arise from the fact that their whole reason for existence is being an open-source copy of github. (And github is designed first and foremost as a public facing opensource management tool... which forces a lot of their product design choices).
Does phabricator work on a different paradigm that's more conducive as an internal tool to manage dev projects for a single organization?
Issues, project management and repositories are fully decoupled.
Instead of copying GitHub with all its flaws, Phabricator was built from scratch for the enterprise usecase.
