Duo Pro is $19/user/month but requires Premium at $29/user/month, making the listed minimum $48 per user monthly; its free agent-platform tier includes zero credits. Compare usage allowances before moving.

02Pricing compared
GitHub Copilot has the lower published entry price: Free includes 2,000 monthly completions, while Pro costs $10 per user per month. Pro+ is $39, and Max is $100. GitLab Duo Pro is $19 per user monthly, but it requires Premium at $29, so the listed minimum is $48 per user monthly. Duo Enterprise is $39 on top of Ultimate at $99, a listed total of $138. Agent Platform pricing is metered by GitLab Credits: Free includes zero credits, Premium includes 12 per user monthly, Ultimate includes 24, and excess usage costs $1 per credit. GitLab says Duo Pro and Enterprise require a one-year commitment when billed annually, but annual prices are unpublished. Copilot's listed paid plans are monthly flat fees, with no annual discount shown. The free options are not equivalent: Copilot includes completions; Duo's free Agent Platform tier includes no credits.
03Features and depth
GitLab Duo is built around agents working inside GitLab's project context and controls. The listed capabilities include turning issues into merge requests, helping remediate vulnerabilities, reviewing code, and using project, issue, and pipeline context. Agent actions appear in an audit trail and follow the same policies and approvals as human changes. That makes its pitch specifically about orchestrating people and agents within GitLab.
Copilot covers coding tasks across GitHub's workflow. Its listed features include issue-linked sessions, separate sessions for parallel tasks, and continuity across the app, CLI, editor, github.com, and mobile. It can run reusable tasks on demand, on a schedule, or through triggers; review local changes and pull requests; and let users select a model or have Copilot balance quality, speed, and cost.
Both list code review. The practical distinction is workflow: GitLab emphasizes shared GitLab context and governed actions; Copilot emphasizes task sessions and moving work across its own surfaces. The published feature lists do not establish which produces better code.
04Ease of use and learning curve
The easier fit is likely the tool already holding your team's work. GitLab Duo's listed agents use existing project, issue, and pipeline context, and their actions follow existing policies and approvals. That may suit teams already coordinating work in GitLab, though the sources do not quantify setup effort.
Copilot connects tasks to issues, discussions, and repository context, with sessions available across several GitHub and development surfaces. That offers more listed ways to continue a task, but does not prove a shorter learning curve. Neither product's published material publishes onboarding time or a comparable measure of admin effort. We would treat ease as a workflow-fit question, not a reason to assume either tool is plug-and-play.
