GitLab is a platform enabling users to develop, share, and test their code. LC formerly supported Bitbucket servers, but retired these in favor of GitLab in Winter 2022.

GitLab uses git, a free and open source tool for version control. Git allows multiple developers to contribute to a shared code base, gracefully integrating changes made by individual developers on independent copies of the code. It tracks the history of code contributions and allows users to create and interact with different versions of the code, where previous changes are undone or selectively applied.

The code base for a given project is stored in a repository or a repo.

A GitLab project contains not only a repository, but also, for example, issues (discussion threads tracking problems or feature requests for the code), and milestones.

GitLab projects provide info about the history and results of continuous integration (CI) testing on the project repository. CI is the process of automatically incorporating new changes to a code base only after verifying that the edited code can pass a standard suite of tests. CI prevents code breakage by helping to identify bugs before they are deployed and allows developers to regularly and frequently alter the code.

Essential to CI are pipelines, which automate the steps needed to test, integrate, and deploy a project’s code whenever changes are introduced.
