Enterprise monorepos offer power and flexibility — but at a cost. As codebases grow and languages multiply, human reviewers struggle to keep up with massive, complex diffs. That’s where CRken comes in. This GitLab-native AI reviewer uses large language models to break down changes, analyze them in context and deliver precise, actionable feedback across 10+ languages. In this post, we explore how CRken helps teams scale code quality without slowing development, making it easier to ship faster, safer and smarter.
