The GitLab open source edition is a developer tool that allows users to collaborate on code, create new projects, manage repositories, and perform code reviews.

When using GitLab, users can keep their code on their own servers, either in the cloud or on-premise. For additional peace of mind, the free community edition even features enterprise-grade features such as a mature user permissions scheme and support for high availability. GitLab is bundled with GitLab CI, a continuous integration server. Just point your projects at the CI server and automate all your tests.
