OpenCodeReview

What it is

Open Code Review is a command-line tool that reads Git diffs, groups changed files into review units, and has an LLM agent with codebase search write line-level review comments. Deterministic steps handle file selection, rule matching, and comment positioning, while built-in rules cover issues such as null pointer errors, thread safety, XSS, and SQL injection. It works with OpenAI- and Anthropic-compatible endpoints and can also scan whole files without a diff. Development teams run it locally, in CI, or from coding agents like Claude Code and Cursor to catch defects before merge.
