GitLab

GitLab is an all-in-one DevSecOps platform that combines Git repository hosting, code review, issue tracking, planning, a container and package registry, CI/CD, and security scanning in a single application. Where GitHub assembles these from separate products, GitLab ships them as one tool with one data model, which appeals to teams that want fewer integrations to maintain.

Its self-managed option is a major draw. The Community Edition is open source under the MIT licence and can run on your own servers with no user limits, which makes GitLab common in regulated industries, government, and organisations that need data sovereignty; the Enterprise Edition adds paid features on the same codebase. GitLab.com is the managed SaaS, and GitLab Dedicated is a single-tenant hosted option.

Work centres on the merge request, with approval rules, code owners, and pipeline results shown inline. GitLab CI/CD runs pipelines defined in .gitlab-ci.yml on shared or self-hosted runners, and security scanning (SAST, dependency, container, and secret detection, with DAST on Ultimate) reports findings directly in the merge request. GitLab Duo adds AI features such as code suggestions, chat, and vulnerability explanations, paid through GitLab Credits.

Pricing is per user per month. The free plan covers core source control and CI/CD but is limited to five users per top-level group for private projects on GitLab.com; Premium adds advanced CI/CD, planning, and support, and Ultimate adds the full security and compliance suite at a sales-quoted price. The breadth has a cost: a dense interface, a steep learning curve, and heavy resource needs when self-hosting at scale.
