GitLab

GitLab is a comprehensive DevSecOps platform that provides a complete software delivery lifecycle solution within a single application, eliminating the need for organizations to integrate and maintain multiple point tools for source control, CI/CD, security testing, project management, and deployment automation. Founded in 2011 and headquartered in San Francisco, California, GitLab serves more than 30 million registered users and 10,000 paying customers worldwide, ranging from individual developers to the largest global enterprises and government agencies.

GitLab Source Code Management provides full-featured Git repository hosting with branch management, merge requests, code review workflows, inline comments, and approval policies. The GitLab web IDE enables developers to make quick edits and view CI/CD pipeline status without leaving the browser, while the AI-powered GitLab Duo assists with code completion, code explanation, merge request summaries, and vulnerability remediation suggestions directly within the development environment.

GitLab CI/CD is the platform's powerful built-in continuous integration and continuous delivery system, enabling teams to define complex multi-stage pipelines as code using YAML configuration files stored in the repository. GitLab Runners execute pipeline jobs in parallel across a variety of execution environments including Docker containers, Kubernetes pods, virtual machines, and shell environments. GitLab's pipeline efficiency features including pipeline caching, DAG scheduling, and parent-child pipelines minimize build times and compute costs.

GitLab Security is a deeply integrated suite of security testing capabilities that automatically run as part of the CI/CD pipeline on every code change. This includes SAST (Static Application Security Testing), DAST (Dynamic Application Security Testing), container scanning, dependency scanning, secret detection, license compliance, and fuzz testing. Security findings are surfaced directly in merge requests, enabling developers to review and remediate vulnerabilities before code is merged to the main branch.

GitLab's project management capabilities include Issues, Epics, Roadmaps, Milestones, and Agile boards that link planning directly to code changes and deployments, providing end-to-end traceability from business requirements through deployment. GitLab can be deployed as a fully managed SaaS service (GitLab.com) or self-managed on any infrastructure including Kubernetes, virtual machines, or dedicated servers.
