Open Source Alternatives to GitLab

A DevSecOps platform that provides a single application for the entire software development lifecycle. The platform integrates planning, source code management, and CI/CD into one data plane to serve as a single source of truth. It includes built-in security tools such as SAST, DAST, and secret detection, which surface findings directly in merge requests and IDEs to help build secure products. The system supports AI agents that automate repetitive tasks like code review, vulnerability remediation, and turning issues into merge requests based on user-defined rules and guardrails. It is used by individuals and enterprises across various industries, including financial services, telecommunications, and the public sector. The software is available via cloud-hosting or self-managed deployment options to meet different regulatory and security requirements.
