AI code review

Compare PR reviewers before you add another GitHub App

AI Choice Engine compares GitHub-app and bundled pull-request reviewers on billing, hourly throughput, git hosts, autofix, merge gates, and dated vendor caveats. Unverified prices stay labelled. Coding assistants such as Cursor the editor live in the harness catalog.

GitHub Copilot code review

Cursor Bugbot

These products comment on pull requests. They are not coding harnesses. Compare Cursor, Claude Code, and Copilot as editors/agents, then come back here if you still need a dedicated reviewer.

CodeRabbit

The broadest dedicated reviewer: GitHub, GitLab, Bitbucket, and Azure DevOps, plus CLI and IDE loops around the PR comment.

Checked August 16, 2026

Open profile Vendor source

Qodo

A governance-heavy reviewer: rules, cross-repo context, and analytics aimed at teams drowning in AI-generated PRs — not only a comment bot.

Checked August 16, 2026

Open profile Vendor source

Greptile

The full-codebase reviewer: it spends credits to keep a graph of the repo, which is the point when bugs live in call sites the diff does not show.

Checked August 16, 2026

Open profile Vendor source

Gitar

A reviewer that treats a red build as the job: comments, then fixes, then re-runs CI. Distinct from comment-only bots.

Checked August 16, 2026

Open profile Vendor source

Graphite

Buy Graphite for stacked PRs and a merge queue; AI review is bundled into the higher plans rather than sold as a standalone GitHub App.

Checked August 16, 2026

Open profile Vendor source

GitHub

GitHub Copilot code review

The default if the team already pays for Copilot: no second GitHub App, no second vendor review.

Checked August 16, 2026

Open profile Vendor source

Cursor

Cursor Bugbot

Cursor’s production reviewer: bug-first, not style-first, and wired back into the Cursor editor the team already switched to.

Review bots do not replace Cursor, Claude Code, or Copilot in the editor.

Common questions

Questions about AI code review

Answered from the verified figures on this page rather than general guidance.

What is an AI code review tool on this page?

A product that comments on pull requests — a GitHub App, a bundled Copilot/Cursor feature, or a stacked-PR inbox. Coding assistants that write code live under /ai-harnesses.

Per seat, credits, or bundled — which is cheaper?

It depends on how many developers open PRs. Per-seat tools (CodeRabbit, Gitar, Greptile Pro) scale with authors. Qodo meters pooled workspace credits. Copilot code review is bundled with a Copilot plan. Compare the dated pricing summary on each profile rather than a single winner.

Do these tools have hourly review limits?

Some do. CodeRabbit caps per developer (1/hour free, 5 Pro, 10 Pro+, 12 Enterprise, rolling). Gitar does not cap manual “Gitar review” comments, but Core/Pro automatic reviews pause when seat headroom for the billing period is exhausted. Qodo and Greptile meter credits. Graphite lists Limited vs Unlimited AI reviews by plan, without an hourly number. Cursor Bugbot bills usage and publishes API per-minute caps, not an hourly PR bucket.

Is GitHub Copilot code review enough?

If the team already pays for Copilot, start there. Dedicated reviewers earn a second vendor only when you need full-repo context, a verifier, CI autofix, or a git host Copilot does not cover.

Did Sonar buy Gitar?

Yes, on 2026-05-21. Gitar remains a standalone product according to Sonar; confirm the support entity and SonarQube bundling before a long contract.
