Open Code Review is an open-source code review orchestration tool and agent plugin suite developed by Alibaba. Built primarily in Go with multi-interface distribution, it enables automated, context-aware code analysis across Git repositories, pull requests, and local development workspaces. In day-to-day workflows, Open Code Review operates as a standalone CLI utility, an npm-distributed tool, or as a plugin integration for IDEs (such as VS Code) and terminal agent environments like Claude Code. It inspects unified diffs and repository context to evaluate code quality, security posture, and logical consistency, generating structured review feedback and inline remediation suggestions. Unlike general-purpose coding agents focused on authoring code, Open Code Review acts as a specialized orchestrator for code validation and peer review workflows. Its architecture leverages modular agent skills and plugin definitions to enforce consistent review standards directly inside terminal sessions, CI workflows, and developer tooling. The project is fully open source under the Alibaba organization on GitHub, making it free to self-host and customize for internal engineering pipelines.
