AI code review tools bill in three different ways (per seat, per review, per credit), and each one sends your pull requests somewhere. This guide is for a CTO or VP of Engineering deciding which bot to put on the PR queue, what it costs for 20 developers, and what leaves the repo when it runs. It's part of our Engineering management guides for CTOs and VPs of Engineering. Every price and data-handling statement below was read from the vendor's own pages on 10 October 2026, and prices change often, so check the page before you sign.
Which AI code review tool fits a team? A quick answer
The order below is a decision path, not a quality ranking. Start with tools that run where your team already reviews code, then dedicated reviewers from lowest to highest published monthly seat price, then the credit-priced option.
| Tool | Short description |
|---|---|
| GitHub Copilot code review | Native to GitHub pull requests, billed in AI credits plus Actions minutes |
| Claude Code Review | Anthropic's multi-step PR review for Team and Enterprise plans, billed on token usage, averaging $15-25 per review |
| Claude Code GitHub Action | Claude running inside your own GitHub Actions workflow |
| Cursor Bugbot | PR reviewer from Cursor, works on GitHub, GitLab, Bitbucket and Azure DevOps |
| CodeRabbit | Dedicated reviewer, per-developer pricing from $24 a month |
| Greptile | Dedicated reviewer, $30 per seat with review credits |
| Graphite | Review tool with unlimited AI reviews on the $40 Team plan |
| Qodo | Pooled credits instead of seats |
If your code is on GitHub and you want the least procurement, start with the first row. If you're on GitLab, Bitbucket or Azure DevOps, Bugbot's docs list GitHub, GitLab, Bitbucket and Azure DevOps. Qodo's site lists them too, so check each tool's page for your host. If you want a predictable bill, the per-seat dedicated tools are the easiest to forecast, though CodeRabbit lists usage add-ons and Greptile bills overage credits.
How we compared them
Each tool was judged on four things you can check yourself: whether the price is visible on the vendor's page, what the billing unit is (seat, review or credit), whether the vendor's own site says anything about data handling, and whether there's a trial. We read the pages on 10 October 2026 and quote them.
We didn't measure accuracy or comment noise, and we won't pretend otherwise. The one benchmark we found, GitHub's ReviewBench, was published on 5 October 2026, covers 219 pull requests from 187 repositories, is built by GitHub and Microsoft staff, and the post describes using it to evaluate GitHub's own Copilot code review. At least one vendor listicle, CodeAnt AI's own, names its own product "Best Overall". A bake-off on your own PRs, described below, beats any of that.
The tools
GitHub Copilot code review
GitHub's code review docs say Business and Enterprise organisations get it, and automatic reviews work on Pro, Pro+, Max and Business or Enterprise licences. The Free plan is excluded. The docs estimate a review at $0.05 to $1 in AI credits on the Lite setting and $0.25 to $5 on Balanced, excluding Actions minutes, which are billed separately (self-hosted runners don't consume them). GitHub publishes these as estimates, not a rate card. Seat prices on GitHub's plans page are Free $0, Pro $10, Pro+ $39 and Max $100 a month; that page doesn't list a Business or Enterprise price, so we don't quote one.
GitHub says Copilot is "not guaranteed to spot all problems." It reviews a PR once unless you configure it per push, skips lockfiles, logs and SVGs, and doesn't let you switch models. Configuration is covered in How to set up GitHub Copilot code review in 2026.
Claude Code Review and the Claude Code GitHub Action
These are two products, and mixing them up is the easiest way to misjudge the bill. Claude Code Review is a research preview for Team and Enterprise plans. It runs on Anthropic's infrastructure and isn't available with Zero Data Retention or a HIPAA configuration. Its findings don't approve or block a PR; the check run reports a neutral conclusion. Anthropic says a review averages $15 to $25, token-based, billed through usage credits separate from plan usage, and takes about 20 minutes. An owner can set a monthly spend cap.
The Claude Code GitHub Action runs in your own workflow. Its cost is Actions minutes plus API tokens, or your subscription if you authenticate with an OAuth token. Setup is /install-github-app, and that route supports github.com repositories only.
Cursor Bugbot
Cursor's Bugbot docs list GitHub (including Enterprise Server), GitLab (including self-hosted), Bitbucket (including Data Center) and Azure DevOps Services. They say "Bugbot Teams bills from on-demand spend" and state no per-user price or PR limit. Cursor's pricing page shows Teams at $40 per user per month and lists "Agentic code reviews with Bugbot" under it, with no separate Bugbot price. So the seat is knowable and the review spend isn't, which makes Bugbot the hardest line item to forecast.
CodeRabbit
CodeRabbit's pricing page lists per developer per month: Essentials $24 billed annually ($30 monthly), Team $48 ($60 monthly), Advanced $72 annual, and Enterprise on request. You're charged only for developers who create PRs. There's a 14-day trial, and public repositories get free reviews. Essentials at $24 per developer on annual billing is the lowest per-seat price among the plans costed in the table below. The page also lists usage-based add-ons ($0.25 per reviewed file once a plan's hourly allowance is reached, $0.40 per agent minute for CodeRabbit Agent), so the seat price isn't the whole bill.
Greptile
Greptile's pricing page has a free Starter plan (one developer, 50 credits) and Pro at $30 per seat per month with 50 credits per seat and $1 per extra credit. A base review costs 1 credit, Plus 3, Apex 10. A seat is a developer who got a review in that period. Pro has a 14-day trial, and Enterprise can be self-hosted. The credit multipliers matter: if your team runs Apex reviews routinely, 50 credits is five reviews, not fifty.
Graphite
Graphite's pricing page lists Hobby free, Starter at $20 per user per month billed annually, and Team at $40 per user per month billed annually with unlimited AI reviews. Enterprise is custom. Team shows a free trial button, but the page doesn't state how long the trial lasts. That unlimited-reviews line is a firmer cost ceiling than the credit- or on-demand-billed tools here, at a higher seat price than Greptile Pro ($30) or CodeRabbit Essentials ($24).
Qodo
Qodo's pricing page sells pooled credits at $0.012 each. It lists 2,500 credits for about 18 reviews a month, 5,000 for about 36, and 20,000 for about 144. A "Pro Team" plan is listed at $30 for up to 30 users, but the page doesn't say per-user, so we don't treat it as a seat price. There's no free tier, and the trial is 14 days with no card. Credit pooling suits a team where a few people open most of the PRs.
What a 20-developer team pays
Seat tools and per-review tools don't compare directly, so the table below converts each to a monthly figure for 20 developers. These are our calculations from the list prices above, using annual billing where the vendor offers it. For per-review tools we assumed 100 reviews a month across the team (about five per developer), which is our assumption, not a vendor number.
| Tool | Billing unit | Our calculation | Monthly total |
|---|---|---|---|
| CodeRabbit Essentials | Seat | 20 x $24 | $480 |
| CodeRabbit Team | Seat | 20 x $48 | $960 |
| CodeRabbit Advanced | Seat | 20 x $72 | $1,440 |
| Greptile Pro | Seat plus credits | 20 x $30, 50 base reviews included per seat | $600 before overage |
| Graphite Team | Seat | 20 x $40 | $800 |
| Cursor Teams | Seat plus on-demand | 20 x $40 | $800 before Bugbot spend |
| Qodo | Credits | 20,000 x $0.012, about 144 reviews | $240 (about $1.67 a review; costed at Qodo's published 144-review tier; at 100 reviews, about 13,900 credits, about $167) |
| Claude Code Review | Token usage, averaging $15-25 per review | 100 x $15 to $25 | $1,500 to $2,500 |
| Copilot, Lite | Per review | 100 x $0.05 to $1 | $5 to $100, plus Actions minutes and the Copilot licence |
| Copilot, Balanced | Per review | 100 x $0.25 to $5 | $25 to $500, plus Actions minutes and the Copilot licence |
Three caveats. CodeRabbit bills only developers who create PRs, so 20 is a ceiling. Monthly billing at CodeRabbit raises Essentials to $600. And the Copilot rows leave out the licence because we have no sourced Business price.
Our read: the per-review tools look cheap at the Copilot end and expensive at the Claude end, and the spread is the point. Claude at $15 to $25 a review is a deliberate "deep review" product, not a default for every PR. If you pick a usage-priced tool, you're metering a new cost line, and Is token usage a good engineering productivity metric? What to report instead covers how to report it.

Where your code goes: data handling compared
This is what each vendor says on the pages we read. "No statement" means the page we read said nothing on the subject, not that the vendor does nothing. Ask for the data processing agreement and the trust center before a pilot.
| Tool | What the vendor says |
|---|---|
| GitHub Copilot | No explicit statement on the code review page, which points to an application card |
| Claude Code Review | Runs on Anthropic infrastructure; not available with Zero Data Retention or a HIPAA configuration |
| Claude Code GitHub Action | No statement on the page; it points to Anthropic's data usage and security docs |
| Cursor Bugbot | Same privacy compliance as Cursor, processing data identically to other Cursor requests; Autofix isn't available in Legacy Privacy Mode |
| CodeRabbit | Never uses customer code for training; code goes to OpenAI and/or Anthropic for review only; caches encrypted code archives and stores code vector representations; Learnings opt-out; Enterprise self-hosting |
| Greptile | SOC 2 Type II; hard delete within 24 hours of admin deletion; backups up to 30 days; may train on de-identified customer data unless you opt out (not on self-hosted); providers include OpenAI and Anthropic |
| Graphite | No statement on the page we read |
| Qodo | "Does not train models on your code"; "strict data retention" with no period defined; single-tenant or on-prem on Enterprise |
The vendor statements come from CodeRabbit's FAQ and Greptile's security page for those two, and from the pricing and docs pages above for the rest. CodeRabbit's FAQ doesn't state SOC 2.
Two things stand out. Greptile's default is the opposite of CodeRabbit's on training, so a security reviewer should read that line before anything else. And "strict data retention" without a period isn't an answer; it's a question to put in writing.
Where AI review sits next to human review
Treat an AI reviewer as a first pass. Claude Code Review's neutral check run and Copilot's "not guaranteed to spot all problems" both point the same way: those two vendors don't position their tools as the final gate. Opinion: keep branch protection tied to a human approval and let the bot comment before the human arrives, so the human spends their time on design and risk instead of typos. Code review best practices for distributed teams covers PR size and review SLAs, which matter more than the bot you choose.
How to trial an AI code review tool in two weeks
This protocol is our judgment, not a vendor recommendation.
Pick two or three tools from different billing models. Run each on 10 to 20 recently merged PRs, or give each to one team for a sprint. Set a spend cap before you start where the tool allows one (Claude Code Review lets an owner set a monthly cap). Copilot's cost shows up on the bill after the fact, so check it daily during the trial. For each tool, count comments your developers acted on against comments they dismissed. That ratio, plus the bill, is your comparison.
Trial terms from the vendors: CodeRabbit has a 14-day trial, Greptile Pro a 14-day trial, Qodo 14 days with no card, and Graphite shows a Team trial of unstated length.
What this means for your AI tooling budget
You're making three decisions, and they should be made in this order. First, whether to add an AI reviewer at all: it's a first-pass filter that can't block a merge on its own, so the case rests on review turnaround and the defects humans were missing, not on replacing reviewers. Second, which billing model your budget can absorb. Seats are forecastable; per-review and on-demand billing aren't, and Bugbot, Copilot and Claude can all drift. Third, whether the data handling clears security review. Greptile's training default, Qodo's undefined retention period and the "no statement" rows are the items to take to your security lead.
My suggestion, labelled as judgment: trial two tools with a spend cap, measure review turnaround and escaped defects against your current baseline, and only then pick one. How to measure AI coding tools ROI: a plan a VP can run gives you the method for that comparison.
FAQ
What is the best AI code review tool for a team?
It depends on where your code lives and how you want to be billed. GitHub teams that want the least setup should start with Copilot code review. Teams that want a forecastable bill should look at the seat-priced dedicated tools. Teams on GitLab, Bitbucket or Azure DevOps should check Bugbot's and Qodo's platform lists. No independent benchmark covers these tools side by side, so trial two on your own PRs.
How much do AI code review tools cost per developer?
From the vendor pages we read on 10 October 2026: CodeRabbit from $24 per developer per month on annual billing, Greptile Pro $30 per seat, Graphite Team $40 per user, and Cursor Teams $40 per user before Bugbot's on-demand spend. Copilot, Claude Code Review and Qodo bill by review or credit, so cost scales with PR volume instead of headcount.
Does AI code review replace human review?
No. Of the vendors we read, GitHub says Copilot is not guaranteed to spot all problems, and Claude Code Review's findings don't approve or block a PR. Use the bot as a first pass and keep a human approval as the merge gate.
Is our code used to train the models?
It varies by vendor. CodeRabbit says it never uses customer code for training. Qodo says it doesn't train models on your code. Greptile may train on de-identified customer data unless you opt out. Bugbot follows Cursor's privacy compliance. Copilot's code review page makes no explicit statement. Get the answer in writing in a data processing agreement.
Can GitHub Copilot do a code review?
Yes. Copilot code review is available to Business and Enterprise organisations, and automatic reviews work on Pro, Pro+, Max and Business or Enterprise licences. It isn't on the Free plan. Admin configuration is covered in the setup guide linked in the Copilot section above.
