Orchestrating AI Code Review at Scale
Cloudflare developed a CI-native orchestration system for AI-powered code review to address scalability and flexibility limitations of existing tools. The system uses up to seven specialized AI agents to review code for security, performance, quality, and compliance, coordinated by a central agent that consolidates feedback. It has been deployed across tens of thousands of merge requests, improving review speed and accuracy while integrating into existing engineering workflows.
- ▪Cloudflare's AI code review system reduces bottlenecks by using specialized AI agents instead of relying on a single monolithic model.
- ▪The system is built on a composable plugin architecture that supports multiple version control systems and AI providers without tight coupling.
- ▪Specialized reviewers cover areas like security, performance, and compliance, with findings deduplicated and prioritized by a coordinator agent.
- ▪The orchestration system integrates with OpenCode, an open-source coding agent, to deliver structured review comments in the CI/CD pipeline.
- ▪It has been used internally at Cloudflare to automatically approve clean code and block merges with serious bugs or security issues.

A merge request sits in a queue, a reviewer eventually context-switches to read the diff, they leave a handful of nitpicks about variable naming, the author responds, and the cycle repeats. Across our internal projects, the median wait time for a first review was often measured in hours.When we first started experimenting with AI code review, we took the path that most other people probably take: we tried out a few different AI code review tools and found that a lot of these tools worked pretty well, and a lot…
