Best Codex plugins for code review
We found 8 listings for code review that work with Codex. 2 of them are in OpenAI's official curated catalog (GitHub, Superpowers), so they install from the built-in marketplace. 6 are community repos that pass our quality filter (not tested by us).
How this list was made: every listing in the CodexStacks catalog whose name or description mentions code review, pull requests, PR review, code quality or linting. "Best" here means "available and documented", not a ranking: we haven't benchmarked these, and there are no paid placements in this list. Order: official OpenAI curated listings first (A–Z), then community repos by GitHub stars at last sync. This is not a quality ranking.
