CodeRabbit vs Greptile: AI Code Review Comparison (2026)

CodeRabbit vs Greptile for pull request review: CodeRabbit is the better fit for most teams that want thorough reviews and a predictable per-developer bill, Greptile fits teams that want per-review credits with no seat fees, and Macroscope is a usage-based third option that caught the most bugs in Macroscope's own 118-bug benchmark. The rest of this page shows the numbers behind that answer.

Greptile vs CodeRabbit is one of the most common AI code review comparisons buyers run, and it usually comes down to three questions: how each tool charges, how many real bugs each one catches, and how each one fits your review workflow. Both are capable AI code review tools. Both review pull requests automatically and leave comments on the diff. They differ in pricing shape and how they find bugs.

This guide compares them on what actually decides the purchase, says plainly when each one is the right choice, and then asks whether a third option is worth a look.

TL;DR: Greptile vs CodeRabbit

• Pricing: CodeRabbit is priced per developer: Essentials is $24 per developer per month billed annually ($30 monthly), Team is $48 annually ($60 monthly). Greptile charges $1 per Base review credit, no seat fees.
• What you pay for: Greptile bills per review credit (Base 1, Plus 3, Apex 10 credits per review). CodeRabbit uses per-developer plans with hourly review rate limits.
• Bug detection: In Macroscope's own 118-bug benchmark, CodeRabbit caught 45.8% (54/118). Greptile caught 23.6% (17/72), and Greptile was only evaluated on 72 of the 118 bugs, so its rate comes from a smaller sample.
• Platforms: CodeRabbit covers GitHub, GitLab, Bitbucket and Azure DevOps. Greptile covers GitHub and GitLab.
• Pick CodeRabbit for the stronger benchmark result and predictable per-developer plans. Pick Greptile for a free single-developer tier, no seat fees, or its startup discount.
• Third option: Macroscope is usage-based (no seats) and scored highest in the same benchmark. It runs as a GitHub App.

CodeRabbit vs Greptile: which is better for pull request review?

For pull request review, CodeRabbit is better for most teams: it caught 45.8% of bugs in Macroscope's benchmark against Greptile's 23.6%, and it covers GitHub, GitLab, Bitbucket and Azure DevOps. Greptile is the better pick when many developers rarely open PRs, because it bills per review credit instead of per seat, or when its free Starter tier or startup discount applies.

What decides the choice on real pull requests:

• Bugs caught. CodeRabbit 45.8% (54/118) versus Greptile 23.6% (17/72, a smaller sample). Macroscope caught 48.3% (57/118) in the same benchmark, which Macroscope runs, so test all three on your own code.
• Comment volume. A reviewer that catches bugs but floods the PR slows review down. See AI code review false positives and signal-to-noise.
• Billing shape. CodeRabbit is per developer, Greptile per review credit, Macroscope per KB of diff reviewed with no seats. Full breakdowns: CodeRabbit pricing and Greptile pricing.
• Platform. If you are on Bitbucket or Azure DevOps, only CodeRabbit of the two supports you. On GitHub, all three run as GitHub PR review apps.

What is the difference between Greptile and CodeRabbit?

The short answer: CodeRabbit is a per-developer AI code review subscription with hourly review limits, and Greptile bills per review credit with no seat fees. Both run on your pull requests and comment on the diff. The day-to-day experience differs less than the pricing model does.

CodeRabbit's plans are tiered by developer, with a cap on how many PR reviews each developer can trigger per hour. Greptile has no seat fees; each review spends credits based on the depth you choose. They are tuned for different buyers.

How does Greptile pricing compare to CodeRabbit pricing?

CodeRabbit charges per developer and layers hourly rate limits on top of seats, while Greptile charges per review credit with no seats. That difference is what shows up on the invoice.

CodeRabbit pricing

As listed on coderabbit.ai/pricing on 2026-11-04: Essentials is $24, Team $48 and Advanced $72 per user per month billed annually, and Essentials is $30 billed monthly. CodeRabbit's pricing FAQ says Essentials is the new name for Pro and Team the new name for Pro Plus.

• Essentials: $24 per developer per month billed annually, $30 billed monthly. (Essentials was formerly called Pro.)
• Team: $48 per developer per month billed annually, $60 billed monthly. (Team was formerly Pro Plus.)
• Advanced: $72 per developer per month billed annually.
• Enterprise: custom.
• Rate limits: each developer can trigger a set number of PR reviews per hour: 5 on Essentials, 8 on Team, 10 on Advanced, 12 on Enterprise.
• Past the limit: pay as you go at $0.25 per reviewed file, with an admin-set monthly cap.
• Free: reviews are free forever for public repositories, and paid plans have a 14-day free trial with no credit card.

Greptile pricing

• Starter: free for 1 active developer with 50 credits per month.
• Paid reviews: $1 per Base review credit, no seat fees. 14-day free trial.
• Credits per review: Base costs 1 credit, Plus costs 3, Apex costs 10.
• Enterprise: custom, with SSO/SAML.
• Discounts: free for qualified non-commercial open-source projects, and 50% off for pre-Series A startups under $2M revenue.

What this means in practice

CodeRabbit's cost is easy to forecast from headcount: seats times plan price, plus pay-as-you-go file reviews past the hourly limit. Greptile's cost depends on how many reviews you run and which depth you choose. Apex spends 10 credits a review against 1 for Base, so depth matters. If every developer opens PRs, CodeRabbit is simpler to budget. If many rarely do, Greptile's per-review billing can work in your favor.

How do Greptile and CodeRabbit review a pull request?

CodeRabbit runs a structured review pass over the diff and posts a summary plus line comments, while Greptile runs an agentic search over the repository to pull in context before commenting. Both claim codebase awareness. The difference is in how they gather it.

CodeRabbit is built for coverage. It summarizes the PR and leaves comments across correctness, style and maintainability. Teams that want an always-on second reader like it. Teams that want only the comments that matter sometimes tune it down.

Greptile is built around search. Its reviewer looks outward from the diff into the rest of the repository, which helps when the risk of a change lives somewhere the PR did not touch. Review depth (Base, Plus, Apex) is a dial between cost and thoroughness.

Both support custom rules. Review quality on your own codebase matters more than either architecture on paper.

Which catches more bugs, Greptile or CodeRabbit?

On Macroscope's own benchmark, CodeRabbit caught a much higher share of bugs than Greptile: 45.8% versus 23.6%. The caveat matters: Greptile was only evaluated on 72 of the 118 bugs, so its rate is measured on a smaller sample than CodeRabbit's.

The Code Review Benchmark is Macroscope's own benchmark, so read it with that in mind. It tests AI code review tools against 118 real production bugs across 8 languages (Go, Java, JavaScript, Kotlin, Python, Rust, Swift, TypeScript) and counts how many each tool flagged.

Tool	Bugs caught	Detection rate
Macroscope	57 of 118	48.3%
CodeRabbit	54 of 118	45.8%
Cursor Bugbot	50 of 118	42.4%
Greptile	17 of 72	23.6%
Graphite Diamond	21 of 115	18.3%

Two honest readings: CodeRabbit is a strong detector on GitHub code review, close to the top and well ahead of Greptile. And Greptile's number is less certain, since a rate measured on 72 bugs has more room to move than one measured on 118. A trial on your own repositories will tell you more.

Detection is also only one axis. A tool that buries its catches in noise can still slow a team down.

Which platforms do Greptile and CodeRabbit support?

CodeRabbit supports GitHub, GitLab, Bitbucket and Azure DevOps. Greptile supports GitHub and GitLab.

On GitHub, the platform most teams evaluate both on, the decision moves to pricing and review quality.

When should you choose CodeRabbit?

Choose CodeRabbit if you want an easy-to-forecast per-developer bill, and value thorough reviews on every PR. It is the default many teams land on for good reasons.

CodeRabbit is the right pick when:

• You want the stronger benchmark result of the two.
• Your headcount is stable, so per-developer pricing is predictable.
• You maintain public repositories and want free reviews on them.
• Your team likes a comprehensive reviewer and has the habit of triaging comments.

When should you choose Greptile?

Choose Greptile if many of your developers rarely open PRs, or if you qualify for its startup discount. It fits a specific set of buyers well.

Greptile is the right pick when:

• You want to pay per review, with no seat fees.
• You want a dial on review depth and cost per PR (Base, Plus, Apex).
• You are a single developer and the free Starter tier covers you.
• You are a pre-Series A startup under $2M revenue and the 50% discount changes the math.

Is there a third option beyond Greptile and CodeRabbit?

Yes. Macroscope is a third option worth evaluating if you are on GitHub and want usage-based pricing instead of seats. It is also the tool that runs the benchmark cited above, so weigh that accordingly and test it on your own code.

Where Macroscope wins

• Detection. Macroscope caught 48.3% (57/118) in the same benchmark, the highest of the tools tested. It explores the surrounding code in the repository to catch bugs across files, the kind where a change in one file breaks a caller the PR never touched.
• Precision. With Code Review v3, overall review-comment precision went up, with 22% fewer comments overall. That directly addresses the "too many comments" complaint some teams have with thorough reviewers.
• No seats. Pricing is usage-based: Code Review costs $0.05 per KB of diff reviewed, with a 10 KB minimum per review ($0.50 floor). There are no per-seat fees, no seat minimums and no annual commitment. Every new workspace gets $100 in usage credit. See what a review actually costs.
• Spend controls. You can cap spend per review or per PR (defaults are $10 per review and $50 per PR, adjustable), set monthly budget limits, turn off auto-review by repo or label, and exclude files.
• More than comments. Fix It For Me opens a fix PR, runs CI and iterates until tests pass. Approvability auto-approves low-risk PRs and escalates risky ones. Check Run Agents let you write custom AI checks in plain-English Markdown that run as GitHub check runs and can block merges.

Where Macroscope does not fit

• Usage pricing is a different shape. Teams that want a fixed per-developer line item may prefer a seat plan.

Macroscope is SOC 2 Type II, does not train models on customer code, and encrypts data at rest and in transit. It is free for qualified non-commercial open-source projects through the open-source program.

How should you run a fair Greptile vs CodeRabbit trial?

Install both on the same repository and score them on the GitHub PR review comments you would actually act on. AI code review tools run in parallel, so there is no need to choose before you have data. Count real catches rather than total comments, watch PRs that change a shared type or function signature, ask the engineers which tool they would keep, and price a normal month under each model. When you settle on one, make AI code review a required check on GitHub so it gates every merge. Adding a third tool takes minutes: see setting up AI code review on GitHub.
