GitLab

GitLab is a complete DevSecOps platform delivered as a single application, providing source code management, CI/CD pipelines, security scanning, container registry, package registry, and project management. Unlike GitHub's marketplace approach, GitLab builds all these capabilities directly into its core platform. GitLab's CI/CD pipeline system is one of the most feature-rich available, supporting complex multi-stage pipelines with parallel execution, directed acyclic graphs, and environments management. The platform also provides a comprehensive security scanning suite including SAST, DAST, dependency scanning, container scanning, and secret detection. GitLab is available as both a SaaS platform and a self-managed installation, giving organizations full control over their DevOps infrastructure when needed. The self-managed option is popular in regulated industries and organizations with strict data sovereignty requirements.
