GitLab Duo Agent Platform is GitLab's built-in multi-agent AI system that automates work across the software development lifecycle — planning, coding, code review, CI/CD troubleshooting, and security triage — directly inside GitLab.com, GitLab Self-Managed, and GitLab Dedicated, built by GitLab Inc.
Who builds it
GitLab, the company behind the widely used GitLab DevSecOps platform, ships Duo Agent Platform as a native capability rather than a bolt-on plugin. Because the agents run inside GitLab itself, they read live context from your issues, merge requests, pipelines, and repositories instead of working from a copy-pasted prompt.
Core features
- Specialized agents: a Planner Agent for work planning and tracking, a Data Analyst Agent for project/metrics insights, a Security Analyst Agent for vulnerability triage and fix suggestions (Ultimate tier), and a CI Expert Agent that creates, debugs, and optimizes CI/CD pipelines (Premium and up, currently beta).
- Pre-built flows: Developer Flow (issue to merge request), Code Review Flow, Software Development Flow, and CI/CD Pipeline Fix Flow, plus support for assembling custom agents and custom flows for team-specific processes.
- Automated code review on merge requests and root-cause analysis of failing CI/CD jobs with suggested fixes.
- Agentic chat for code generation, refactoring, and test generation with GitLab context.
- Governance controls: policy-driven, org-level access permissions, flow sessions logged and visible in GitLab with links back to CI/CD job logs, and support for connecting self-hosted LLMs.
- Data handling: GitLab states private code is not used to train its AI models, and that the third-party model vendors it relies on do not train on private customer data either; IP indemnification is offered for Duo-generated output.
Pricing
- Free: the Free GitLab tier lets you evaluate the platform; GitLab Duo Core (code suggestions, and agentic chat from GitLab 19.0) ships automatically with GitLab 18.0+ on Premium/Ultimate.
- Premium: $29/user/month billed annually, including $12 of GitLab Credits per user per month for Agent Platform usage.
- Ultimate: custom, contact-sales pricing, including $24 of GitLab Credits per user per month.
- Additional GitLab Credits are purchasable at a standard rate of $1/credit, with volume discounts on annual commitments.
- Duo Pro and Duo Enterprise add-ons are sold as seats; GitLab directs buyers to its Sales team or Customers Portal instead of publishing a fixed add-on price.
- Self-hosted/offline deployments of the Agent Platform are billed as a flat fee under an Enterprise License Agreement rather than through usage-based credits.
Who it's for
Teams that already run their planning, code, and pipelines on GitLab and want AI agents wired directly into that existing system of record, rather than adopting a separate standalone tool. Because agent access and included credits scale with the Premium and Ultimate tiers, it fits mid-size engineering teams enabling the CI Expert Agent for pipeline debugging as well as larger, regulated organizations using the Ultimate tier's Security Analyst Agent for SAST vulnerability triage.
