GitLab Duo is the suite of AI-powered features integrated throughout the GitLab DevSecOps platform, providing AI assistance across every stage of the software development lifecycle from planning and coding through testing, security, deployment, and monitoring. GitLab was founded in 2011 by Dmitriy Zaporozhets and Sid Sijbrandij, with the company headquartered in San Francisco, California, operating as an all-remote organization. GitLab Duo encompasses multiple AI capabilities that are deeply integrated into the platform rather than offered as standalone tools. Code Suggestions provides AI-powered code completion and generation directly within the GitLab Web IDE and supported editors, supporting multiple programming languages with context-aware suggestions drawn from the current file and project. GitLab Duo Chat is a conversational AI assistant available throughout the platform that can explain code, summarize issues and merge requests, generate tests, identify vulnerabilities, and answer questions about GitLab features. For security, GitLab Duo includes AI-powered vulnerability explanation and resolution, which analyzes detected security vulnerabilities and suggests specific code fixes. The platform provides AI-assisted code review that summarizes merge request changes and identifies potential issues, AI-generated issue descriptions and test cases, and root cause analysis for CI/CD pipeline failures. GitLab Duo also offers value stream forecasting that uses AI to predict delivery timelines based on historical data. All GitLab Duo AI features are designed with privacy in mind, with options for self-hosted AI models for organizations with strict data residency requirements. GitLab is available as a SaaS platform or as a self-managed installation. GitLab Duo features are included in Premium ($29/user/mo) and Ultimate ($99/user/mo) tiers, with a free tier available for basic Git repository hosting and CI/CD functionality.
