Frequently asked questions

What is the main difference between pull requests and merge requests?

Pull requests (GitHub terminology) and merge requests (GitLab terminology) are functionally equivalent tools for proposing code changes, facilitating review, and merging code. GitHub uses 'pull requests' whilst GitLab uses 'merge requests'. The underlying workflow and purpose are identical.

Which code review platform is best for enterprises?

GitHub, GitLab, and Atlassian Bitbucket are the primary enterprise choices. GitHub dominates market share with excellent scalability. GitLab offers integrated CI/CD and security scanning. Bitbucket excels for organisations already using Jira. Gerrit suits enterprises with custom approval workflows.

Can I self-host these platforms instead of using cloud versions?

GitHub, GitLab, and Bitbucket offer self-hosted versions. Gerrit, Gitea, Review Board, Gitbucket, Phabricator, Fossil, and Gogs are entirely self-hosted open-source options. Self-hosting provides data control but requires infrastructure management and maintenance responsibility.
