1.) Time-saving automation : helps with repetitive tasks like generating code snippets, writing test cases, summarizing merge requests, etc. 2.) Context-Aware suggestions : Since it works within GitLab, it leverages project context like past commits, CI logs, etc for more relevant AI responses. 3.) Multi-Role benefits : It is useful not just for developers but also for Security teams, QA engineers, DevOps, etc

    GitLab Duo Enhances Automation and Security but Falls Short in Pure Development

    4.0
    Jun 2, 2025
    GitLab Duo is a powerful AI assistant for the teams already using gitlab, especially those invested in DevSecOps. It shines in automation and security but may not replace standalone AI coding tools for pure development tasks.
