GitLab Duo
AI across the DevSecOps lifecycle
GitLab Duo is a suite of AI-native features embedded across the entire GitLab DevSecOps platform, providing AI-assisted code generation, vulnerability detection, test automation, and root cause analysis within the tools developers already use. It brings AI capabilities to every stage of the software development lifecycle from planning to monitoring.
Key Capabilities
GitLab Duo provides AI-assisted code generation, code completion, and refactoring directly within supported IDEs. Its Agentic Chat feature offers multi-step reasoning using full GitLab context including issues, merge requests, pipelines, and security findings. Root Cause Analysis scans CI/CD logs, error messages, and recent code changes to pinpoint failure causes. Additional capabilities include vulnerability detection, test generation, documentation writing, and project summarization, all leveraging the rich context of the GitLab platform.
Who Should Use GitLab Duo
GitLab Duo is designed for teams already using GitLab as their DevSecOps platform who want AI capabilities deeply integrated across their existing workflow. It is particularly valuable for enterprises that prefer a single-vendor approach to DevSecOps with AI, rather than adding separate AI coding tools to their stack.
Getting Started
GitLab Duo Core is automatically included with GitLab 18.0+ Premium and Ultimate subscriptions. For advanced AI features, add GitLab Duo Pro ($19/month per user) or Duo Enterprise ($39/month per user) to your existing GitLab subscription.
