Engineering teams evaluating AI coding assistants face a choice between architectural depth and platform consolidation. Consider a common scenario: the CI pipeline has failed three times this week, and the security team requests audit trails for every AI-powered code review. Engineering teams have two options for addressing this with AI assistance, and they approach these problems from entirely different directions.

Augment Code works as a context-aware teammate that plugs into whatever stack teams are already running. GitLab Duo embeds intelligence directly into GitLab's platform, making AI feel native to existing DevSecOps workflows.

Both tools promise to make pipelines smarter, code reviews faster, and compliance easier. This comparison helps engineering managers and senior developers determine which approach aligns with their organization's architecture and workflow requirements.
