Graphite vs CodeRabbit for PR reviews: an honest take

We sell neither Graphite nor CodeRabbit (we build Pyor, a review surface that sits next to both, so read this with that in mind). The two get compared as if they were the same kind of product, but Graphite is a pull request workflow and CodeRabbit is a review bot that joins the workflow you already have. We checked everything below against the vendors’ own pages and one open benchmark in October 2026, and where the sources disagree we say so.

What each one is for

Graphite is a pull request workflow platform for GitHub. Its core is stacked pull requests: a CLI and a VS Code extension that let you split a big change into a chain of small dependent PRs without the rebase bookkeeping. Around that sit a stack-aware merge queue, a PR inbox, Slack notifications, team insights, and an AI reviewer. Graphite’s homepage calls it “the AI code review platform”, but what your team adopts is the platform, and the reviewer comes with it.

CodeRabbit is a dedicated AI review agent. You install it, and it reviews every pull request with line comments, a summary, one-click fixes, and pre-merge checks. Per its docs it runs on GitHub, GitLab, Azure DevOps, and Bitbucket, in VS Code, Cursor, and Windsurf through an extension, and from a CLI before you commit. Your team branches and merges the same way it did before.

AI review quality on an open benchmark

Most “benchmarks” you will find for these two are run by a vendor, and the vendor tends to win. The one we trust most is Martian’s Code Review Bench, because its method and code are open source and Martian runs every tool itself rather than taking submitted results. It has two modes, and both include CodeRabbit and Graphite.

The offline benchmark uses 50 PRs from five open source projects (Sentry, Grafana, Cal.com, Discourse, and Keycloak) with human-verified “golden” comments, then has an LLM judge match each tool’s comments against them. In the snapshot dated September 8, 2026 (default judge and category profile), CodeRabbit scored 42.2% F1 with 59.5% recall and 32.6% precision. Graphite scored 14.1% F1: it made 12 correct comments and zero wrong ones, for 100% precision, but found only 7.6% of the known issues.

The live benchmark is the one we weigh more. It samples fresh merged PRs on GitHub where a bot commented, and counts a bot comment as useful when it matches a fix the developer made afterwards. Over December 25, 2025 to October 17, 2026, with the leaderboard’s filters cleared, CodeRabbit sat at 52.2% F1 (54.2% precision, 50.2% recall) across about 48,900 scored PRs. Graphite sat at 41.5% F1 (64.9% precision, 30.6% recall) across about 1,460. You only see Graphite once you clear the default volume filters, since it reviews far fewer public PRs than CodeRabbit does.

Both modes show the same trade. Graphite’s reviewer says little, and what it says is usually right. CodeRabbit says a lot more and catches a lot more, with more comments that go nowhere. Graphite’s own AI reviews page leans into that trade (it claims a negative comment rate under 5% in its own tests, without publishing the method). An older July 2025 test published by Greptile points the same way (CodeRabbit caught 44% of 50 planted bugs, Graphite 6%), but Greptile sells a competing reviewer and scored itself highest, so weigh it as a vendor claim.

Precision decides how much of your reviewers’ time the bot burns, and recall decides how much it saves them from missing. We cover why benchmarks disagree in how accurate AI code review really is. A two-week trial on your own PRs will tell you more than any of these numbers.

Pricing and free tiers in 2026

As of October 2026, Graphite’s pricing page lists annual prices only, and CodeRabbit’s lists annual prices with monthly prices in its FAQ.

For unmetered AI review on private org repos, Graphite starts at $40 a seat and CodeRabbit at $24. Graphite’s $40 also buys the merge queue and stacking workflow, so if you would not use those, you are paying for a platform to get a reviewer. Model CodeRabbit’s usage pricing before you commit: Essentials allows 5 reviews per developer an hour, and continued reviews bill per file, with an admin spending cap to stop surprises.

Workflow lock-in and who owns what

CodeRabbit is easy to leave. It is an app on your repos, so when you uninstall it, your PRs, branches, and merge process stay exactly as they were. You lose its configuration and the “learnings” it has collected from your team’s feedback. It also follows you across hosts, which matters if part of the org lives on GitLab or Bitbucket.

Graphite asks for more commitment, by design. The AI reviewer alone is not sticky: Graphite’s setup docs say it reviews all new PRs in the repositories you pick, with no stacking required. But $40 a seat is a lot to pay for the reviewer alone. You get your money’s worth when the team branches through the Graphite CLI and merges through its queue, and unwinding that means changing how everyone works. Its setup docs also only describe GitHub.

Graphite’s ownership has changed too. On December 19, 2025, Graphite signed a definitive agreement to join Cursor (the company is Anysphere). Both companies said Graphite would keep operating as an independent product, and Graphite’s post lists plans to combine its AI reviewer with Cursor’s Bugbot into one reviewer. Since then Graphite has shipped Cursor Cloud Agents inside Graphite (March 2026, for paid Cursor plans), and Cursor itself was acquired by SpaceX in August 2026. Graphite works the same today, but its reviewer may change shape, and its roadmap now follows Cursor’s.

If stacking is the draw, GitHub now ships native stacked pull requests in public preview, which we cover in GitHub stacked pull requests. Graphite is far more mature today, but it is no longer the only way to stack.

Who should pick which

• Pick CodeRabbit if you want an AI first pass on every PR without changing your workflow, you are on more than one git host, or you want the reviewer that catches the most on the open benchmark and can live with more comments to triage.
• Pick Graphite if your team will actually adopt stacked PRs and a merge queue. Stacking gets you smaller PRs, and the reviewer rides along as a quiet extra that rarely wastes your time.
• Use both if you want Graphite’s stacking and CodeRabbit’s catch rate. Turn Graphite’s reviewer off on those repos, or you will read two bots on every PR.

If you are looking for a Graphite competitor because you only ever used the reviewer, you have the clearest case for switching: a dedicated bot does that job for less. Our Graphite alternatives and CodeRabbit alternatives posts map the rest of the field.

When neither is the bottleneck

On a lot of teams (ours included), the slow part of review is a human reading a big diff. The bottleneck shifted from producing code to reviewing it. A bot adds comments to read and stacking changes how PRs are cut, but if your PRs are a 20K-line migration that cannot be stacked, or agent-written changes that land faster than anyone reads them, a reviewer bot hands you one more layer of text, and you still have to read the code anyways.

That is the problem we built Pyor for (yes, this is the plug, kept short). Pyor is a review surface for GitHub PRs, on the web and as a desktop app for macOS, Windows, and Linux. It is not an AI reviewer, and its AI posts no comments: it groups and labels the diff and drops short hints so you read the code that matters first and skim the noise. It adds PRs to GitHub’s merge queue rather than running its own, and while it does not create stacks, it surfaces GitHub native stacks while you review. Pyor is free for individuals and $7.99 per seat a month for orgs, and it works next to either tool here. The feature-by-feature versions are in Pyor vs Graphite and Pyor vs CodeRabbit.
