Quick Verdict
Choose GitLab if you want a modern, SaaS-first integrated DevOps platform and are willing to pay for it. Choose Phabricator if you require a powerful, self-hosted, and completely open-source suite and have the resources to maintain it.
GitLab and Phabricator are both comprehensive, all-in-one platforms for the software development lifecycle. Their core difference lies in delivery and philosophy: GitLab is a commercially-driven, cloud-native SaaS (with self-managed options) that prioritizes a unified, modern UI and continuous feature delivery. Phabricator is a community-driven, self-hosted open-source suite built from a set of powerful but more independently conceived tools. GitLab uses a per-user subscription model, while Phabricator is free to download and run.
