Open Code Review is an AI code review command line tool from Alibaba, licensed Apache 2.0. The README says it began as Alibaba's internal review assistant, and that it reads your Git diff, sends changed files to a language model you configure, and returns structured comments with line-level positions. Engineering code, not the model, picks which files to review, bundles related files into sub-agents and matches rules to each file, which the README offers as the answer to agents that skip files or report the wrong line. The ocr review command covers your working changes, a branch range or one commit, and ocr scan reviews whole files. Install the CLI with npm install -g @alibaba-group/open-code-review, or as a Claude Code plugin that adds /open-code-review:review and /open-code-review:delegate-review. It needs Git 2.41 or newer. In its default mode it calls the model you set up with your own API key, not your Claude subscription, while delegate mode lets your coding agent do the review. The README reports a benchmark of 200 pull requests with higher precision but lower recall than a general agent, and that is Alibaba's own result, which we have not repeated. The repository was last pushed on 12 November 2026. We have not run it ourselves.
