Each repository is part of a gitlab project, and cannot exist without a gitlab project. In gitlab might move to a single rails codebase, we announced that gitlab might move to using a single codebase for gitlab community edition (ce) and gitlab enterprise edition (ee). It adds a gitlab workflow panel to the vs code sidebar where you can view issues, merge requests, and pipelines, and extend your view with custom queries.
Gitlab ce is free open source software licensed under the mit license. The gitlab workflow extension for visual studio code integrates gitlab duo and other gitlab features directly into your ide. You can do pretty much whatever you want with gitlab ce, including (but not limited to) using it within commercial enterprises.
This project was previously used to host gitlab community edition, but all development. Connect with open source enthusiasts on the gitlab forum to find support and collaborate. Since then we have decided to continue moving toward a single codebase.
