GitLab provides source control, CI/CD, security scanning, and project management in one integrated platform. Available as SaaS or self-hosted.
GitLab's value proposition is consolidation — instead of stitching together GitHub, Jenkins, Jira, and separate security tools, GitLab provides all of these capabilities in a single application. Source control, CI/CD pipelines, container registry, security scanning, issue tracking, and deployment management all work together seamlessly. The self-hosted option (GitLab CE/EE) makes it popular in regulated industries and organizations that need to keep code on their own infrastructure. GitLab's "single DevOps platform" approach reduces tool sprawl and provides end-to-end visibility from code to production.
