Description
OpenQodex is an open-source AI code review tool designed to integrate seamlessly with various coding agents, including Claude Code, Codex, Cursor, and Cline. Its primary function is to perform comprehensive code reviews before code is pushed, helping developers identify and address potential issues early in the development cycle.

The system operates by first running a suite of built-in scanners that are tailored to the changed files. These scanners identify potential findings, which are then retained on the specific lines of code that have been altered. Following the scanning phase, a fresh Claude Code or Codex process is initiated, devoid of any prior session memory, to act as a separate reviewer. This reviewer examines the changes, along with the surrounding code, and provides evidence for each candidate finding by quoting relevant lines. A script meticulously verifies every quoted line against the actual code to ensure accuracy.
Upon completion of the review, users receive a detailed receipt that includes a verdict (passed or blocked) and one line per finding. The integrated agent then prompts the user with options such as "Fix all, or tell me which?", allowing for selective application of fixes. OpenQodex also generates a comprehensive code graph, offering insights into the code's structure and relationships. This graph provides capabilities to find definitions, understand call hierarchies, identify importers and implementers, trace paths between points, and assess the impact of changes.
The tool supports a wide range of programming languages, including TypeScript, TSX, JavaScript, Python, Go, and Ruby, and offers framework plugins for Django, Rails, Express, React, Next.js, FastAPI, and Go net/http. It emphasizes privacy by design, running the reviewer on the user's existing Claude Code or Codex login without requiring its own account or API key. The built-in scanners do not transmit code, and the system explicitly states it collects no telemetry. For GitHub Actions, an Anthropic API key is required. OpenQodex is designed for macOS and Linux environments, with no tested support for Windows or WSL.
Performance benchmarks demonstrate its effectiveness, with Claude Code achieving an issue recall of 84.3% and precision of 97.3% to 100.0%, and Codex achieving 75.2% issue recall and 85.6% to 100.0% precision. The cost per review for Claude Code is measured at approximately $0.0870. The tool is open source under the Apache 2.0 license and is available at no cost (USD 0).
