Open Code Review

Open Code Review is an open-source, AI-powered command-line tool for reviewing software changes. It is intended for developers and teams that want automated analysis of Git diffs. The tool originated as Alibaba Group’s internal AI code review assistant and was later released as an open-source project. It uses a configurable model endpoint, allowing users to connect it to a chosen large language model.

The tool reads Git diffs and sends changed files to a language model through an agent with tool-use capabilities. Rather than examining only the visible patch, the agent can read complete file contents, search the codebase, and inspect other changed files for context. It produces structured review comments with line-level precision. This enables reviews that can consider relationships across files and identify issues beyond surface-level diff feedback.

Open Code Review is available for Windows and fits the developer-tools category as a command-line code review utility. Its open-source license allows the project to be used and examined as open-source software. This provides a direct catalog distribution of the official build while preserving its command-line workflow.
