Greptile vs CodeRabbit: An Honest AI Code Review Comparison (2026)

A fair head-to-head of Greptile vs CodeRabbit for AI code review in 2026: pricing models side by side, how each one reviews a pull request, benchmark bug detection, platform support, and when each is the right pick. Plus whether a third option fits better.

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 which Git platforms each one supports. Both are capable AI code review tools. Both review pull requests automatically and leave comments on the diff. They differ in pricing shape, platform reach, 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: Both are priced per developer. CodeRabbit Essentials is $24 per developer per month billed annually ($30 monthly), Team is $48 annually ($60 monthly). Greptile Pro is $30 per seat per month with 50 credits per seat and $1 per extra credit.
  • What a seat means: Greptile counts a seat as any developer who got a Greptile review in the billing period. 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, with self-hosting on its Enterprise plan.
  • Pick CodeRabbit for broad platform coverage and predictable per-developer plans. Pick Greptile for self-hosting, a free single-developer tier, or its startup discount.
  • Third option: Macroscope is usage-based (no seats) and scored highest in the same benchmark, but it is GitHub-only.

What is the difference between Greptile and CodeRabbit?

The short answer: CodeRabbit is a per-developer AI code review subscription with broad platform support, and Greptile is a per-active-seat subscription with a credit system and a self-hosting option. Both run on your pull requests and comment on the diff. The day-to-day experience differs less than the pricing and deployment model do.

CodeRabbit's plans are tiered by developer, with a cap on how many PR reviews each developer can trigger per hour. Greptile's seat only counts if the developer actually got a Greptile review that billing period, and each review spends credits based on the depth you choose. They are tuned for different buyers.

How does Greptile pricing compare to CodeRabbit pricing?

Both tools charge per developer, but CodeRabbit layers hourly rate limits on top of seats while Greptile layers credits on top of seats. That difference is what shows up on the invoice.

CodeRabbit pricing

  • 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.
  • Pro: $30 per seat per month, 50 credits included per seat, $1 per extra credit. 14-day free trial.
  • Seat definition: a seat is any developer who got a Greptile review in that billing period. Active developers, not headcount.
  • Credits per review: Base costs 1 credit, Plus costs 3, Apex costs 10.
  • Enterprise: custom, with self-hosting, SSO/SAML and GitHub Enterprise.
  • 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 developers actually get reviewed and which depth you run. Apex spends 10 credits a review against 50 included per seat, so depth matters. If every developer opens PRs, CodeRabbit is simpler to budget. If many rarely do, Greptile's active-seat definition 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.

ToolBugs caughtDetection rate
Macroscope57 of 11848.3%
CodeRabbit54 of 11845.8%
Cursor Bugbot50 of 11842.4%
Greptile17 of 7223.6%
Graphite Diamond21 of 11518.3%

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 has the broader platform coverage: GitHub, GitLab, Bitbucket and Azure DevOps. Greptile supports GitHub and GitLab, and its Enterprise plan adds self-hosting and GitHub Enterprise.

That makes the platform question decisive for some teams:

  • On Bitbucket or Azure DevOps: CodeRabbit is the option between these two.
  • Need to self-host the reviewer: Greptile Enterprise offers self-hosting. If your security posture rules out a hosted reviewer, that narrows the field quickly.
  • On GitHub or GitLab: both work, and the decision moves to pricing and review quality.

When should you choose CodeRabbit?

Choose CodeRabbit if you need broad Git platform support, 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:

  • Your code lives on Bitbucket or Azure DevOps, or across several platforms.
  • 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 you need to self-host, 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:

  • Security or compliance requires a self-hosted AI code reviewer (Enterprise).
  • You only want to pay for developers who actually got a review that month.
  • 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 builds an AST-based graph of the codebase 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 to 98%, up from 75%, 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

  • GitHub only. Macroscope runs as a GitHub App. GitLab and Bitbucket are not supported. If you are on either, CodeRabbit or Greptile is the better answer.
  • No self-hosting. If you must self-host, Greptile Enterprise is the option of these three.
  • 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. Adding a third tool takes minutes: see setting up AI code review on GitHub.

Frequently Asked Questions

Greptile vs CodeRabbit, which is better?

It depends on what you need. CodeRabbit is better for most teams that need broad platform support (GitHub, GitLab, Bitbucket, Azure DevOps) and a predictable per-developer bill, and it scored higher in Macroscope's benchmark: 45.8% versus Greptile's 23.6%, with the caveat that Greptile was only evaluated on 72 of the 118 bugs. Greptile is better if you need to self-host, want to pay only for developers who actually got a review, or qualify for its startup discount.

CodeRabbit vs Greptile vs Macroscope?

CodeRabbit is a per-developer subscription ($24 annual or $30 monthly on Essentials) with the broadest platform support. Greptile is per active seat ($30 on Pro) plus credits, with self-hosting on Enterprise. Macroscope is usage-based at $0.05 per KB of diff reviewed with no seats, scored highest in its own benchmark at 48.3%, and is GitHub-only. Pick CodeRabbit for multi-platform coverage, Greptile for self-hosting, and Macroscope for GitHub teams that want usage pricing and the highest benchmark detection.

Which AI code review tool catches the most real bugs?

In Macroscope's own benchmark of 118 real production bugs across 8 languages, Macroscope caught 48.3% (57/118), CodeRabbit 45.8% (54/118), Cursor Bugbot 42.4% (50/118), Greptile 23.6% (17/72, evaluated on 72 bugs only) and Graphite Diamond 18.3% (21/115). It is a vendor benchmark, so the best confirmation is running two or three tools side by side on your own pull requests.

How do AI code review tools compare on bug detection?

The clearest public comparison is Macroscope's Code Review Benchmark, which counts how many of 118 real production bugs each tool flags. The top three (Macroscope, CodeRabbit, Cursor Bugbot) sit between 42.4% and 48.3%. Greptile and Graphite Diamond were tested on smaller subsets of the bugs and scored 23.6% and 18.3%. Detection should be read alongside precision: a tool that catches bugs but floods the PR with comments can still cost a team time.

How much does Greptile cost compared to CodeRabbit?

Greptile Pro is $30 per seat per month with 50 credits per seat and $1 per extra credit, where a seat is any developer who got a review that period. CodeRabbit Essentials is $24 per developer per month billed annually or $30 monthly, and Team is $48 annually or $60 monthly. CodeRabbit adds pay-as-you-go file reviews at $0.25 per file once a developer passes the hourly review limit.

Does Greptile or CodeRabbit support GitLab and Bitbucket?

Both support GitLab. CodeRabbit also supports Bitbucket and Azure DevOps, so it is the option between the two if your code lives on either of those. Greptile supports GitHub and GitLab, with self-hosting and GitHub Enterprise on its Enterprise plan. Macroscope supports GitHub only.

Are Greptile and CodeRabbit free for open source?

CodeRabbit offers free reviews forever on public repositories. Greptile is free for qualified non-commercial open-source projects. Macroscope is also free for qualified non-commercial open-source projects.

Can I self-host Greptile or CodeRabbit?

Greptile offers self-hosting on its Enterprise plan, alongside SSO/SAML and GitHub Enterprise. If self-hosting is a hard requirement, Greptile is the clearest answer among these tools. Macroscope does not offer self-hosting.
