GitLab CE
An open source DevOps platform that combines Git repository hosting with issue tracking, merge requests, CI/CD pipelines, a package registry and wikis in a single application. The community edition covers the core workflow, from pushing code and reviewing changes to defining pipelines that build, test and deploy every commit.
Teams use it to replace a scattered set of separate tools with one place to track work from commit to production.
The service can it in your own perimeter, keeping repositories, pipeline logs and package artifacts inside the network, with no per-seat licensing as the team grows and one backup target for source and CI data.
