Claude Code is not one reviewer but several products: Anthropic's managed Code Review, the Claude Code GitHub Action you run in your own workflows, and the /code-review command in your terminal, with an ultra mode that runs in the cloud. Code Review is a research preview for Team and Enterprise plans on GitHub, billed per review from usage credits, $15 to $25 on average by Anthropic's docs. CodeRabbit bills per developer who creates pull requests, from $24 per developer per month billed annually, and lists GitHub, GitLab, Azure DevOps and Bitbucket. CodeRabbit also runs inside Claude Code as a plugin, so the answer is often both; choose by code host, billing unit, where the review runs, and whether the reviewer sits outside the session that wrote the code.
Every fact below comes from each vendor's own pages as I read them on 11 October 2026, and neither Anthropic nor CodeRabbit saw this text before publication.
The four options side by side
In Anthropic's words, "Several products share the Claude Code name." Each cell is from the vendor's own pages, read on 11 October 2026; links are at the end.
| CodeRabbit | Claude Code Review (managed) | Claude Code GitHub Action |
/code-review in your terminal |
|
|---|---|---|---|---|
| Status | paid plans Essentials, Team, Advanced, Enterprise, plus Free | "research preview" | "open source and available", per Anthropic | a Claude Code command, also run as /review; its ultra mode is a research preview |
| Code hosts | GitHub, GitLab, Azure DevOps, Bitbucket Cloud and Data Center, GitHub Enterprise Server, self-managed GitLab | GitHub; GitHub Enterprise Server on Team and Enterprise, if Anthropic's infrastructure can reach it | GitHub; for GitLab, a separate integration "currently in beta" and "maintained by GitLab" | any local diff; --comment posts to a GitHub pull request or a GitLab merge request |
| When it reviews | when a pull request opens against the main branch, then as you push, skipping draft pull requests unless configured to include them; @coderabbitai review (incremental) or @coderabbitai full review
|
per repository: Once after PR creation, After every push, or Manual; @claude review for one review, @claude review always to follow later pushes; "20 minutes on average" |
on your workflow's events; the review workflow skips draft, closed and trivial pull requests and those Claude already commented on | when started: your branch and uncommitted changes, or a PR, a branch or a ref range |
| What you pay for | developers who create pull requests: Essentials $24 per developer per month billed annually or $30 monthly, Team $48 or $60 | each review, averaging $15-25 per review from usage credits outside the plan; After every push multiplies that by the number of pushes | GitHub Actions minutes, plus Claude API tokens or, with an OAuth token, your Claude subscription | normal Claude Code usage; ultra has 3 free runs on Pro and Max, once per account, then typically $5 to $25 per review |
| Plan you need | Free gives PR summaries, with reviews in the VS Code extension and CLI; open-source projects get Team features without paying | Team or Enterprise, not Pro or Max; not for organizations with Zero Data Retention or the HIPAA configuration | a Claude API key, or an OAuth token on Pro, Max, Team or Enterprise | plans without Code Review too: "On other plans, you can still review a diff locally" |
| Where it runs | "Sandboxed cloud execution with your full repository cloned for isolated analysis"; self-hosted on Enterprise from 500 user seats | "on Anthropic infrastructure" | GitHub-hosted runners, calling the Claude API, Amazon Bedrock, Google Cloud's Agent Platform or Microsoft Foundry | your machine, as a background subagent with its own context window; ultra in a cloud sandbox |
| How a finding is checked | a Verification agent among "Specialized AI agents working in parallel" | "a verification step checks candidates against actual code behavior to filter out false positives" | set by your workflow; the review workflow runs Anthropic's code-review plugin |
at low effort it reports the findings it is most confident in; with ultra, "every reported finding is independently reproduced and verified" |
| What lands on the pull request | comments that update as you push; @coderabbitai approve resolves its threads and attempts to approve, for teams that require it as a reviewer |
inline comments by severity and a check run that "always completes with a neutral conclusion" | an inline comment on each issue, or one summary comment when it finds none | nothing unless you pass --comment; --fix applies the findings to your working tree |
| Training on your code | "CodeRabbit never uses customer code for model training." | no, under commercial terms (Team, Enterprise, API), unless the customer opts in | by account: commercial terms for an API key; Anthropic trains on data from Free, Pro and Max accounts when the setting is on | the same rule, by account |
Why not just ask Claude Code to review the pull request?
You can, and Anthropic documents how. The /code-review command reviews a diff "without installing the GitHub App", follows your CLAUDE.md "like any Claude Code session", and "runs as a background subagent with its own context window"; --comment posts the findings to the pull request. It runs when started, so a later push gets a review only when it is run again.
The services differ in what happens after the first review. CodeRabbit "reviews new pull requests automatically and updates its feedback as you push new commits", and Code Review in After every push mode keeps "catching new issues as the PR evolves and auto-resolving threads when you fix flagged issues". That record on the pull request, repeated on every push, is what a one-off prompt does not keep for you. Whether a reviewer that shares the author's model misses more bugs is a fair question that none of the pages I read measures; the test at the end of this article is the closest a team can get on its own code.
What each one costs, in its own unit
A CodeRabbit seat includes reviews up to an hourly limit: "Essentials includes 5 PR reviews per hour" on a rolling window, and sustained use lowers the refill rate, down to "1 review/hour, one review at a time" after 60 or more reviews in 7 days. Past the limit, reviews wait unless usage-based reviews are on, at $0.25 per reviewed file. One detail to check before a trial ends: at the first eligible overage, CodeRabbit turns usage-based reviews on in Automatic mode unless an admin already chose Off or On demand; trial overages are free, and the choice carries over into a paid subscription unless someone turns it off.
Anthropic's managed Code Review bills per review: "Each review averages $15-25 in cost, scaling with PR size, codebase complexity, and how many issues require verification." It is "billed separately through usage credits and does not count against your plan's included usage", and in Manual mode "cost accrues only from reviews someone requests".
One recipe, not a measurement: Anthropic's average for one managed review ($15 to $25, its Code Review page) is in the same range as one month of one CodeRabbit Essentials seat billed annually ($24, its pricing page), and that seat covers its developer's pull request reviews up to the hourly limit. Which bill comes out lower depends on how many pull requests each developer opens and how often they push, so run both with your own counts.
Running both
CodeRabbit documents a plugin for Claude Code: /plugin install coderabbit, then /coderabbit:coderabbit-review reviews your local changes through the CodeRabbit CLI. Both tools read the same instruction file: CodeRabbit "automatically detects coding guideline files such as .cursorrules, CLAUDE.md, and AGENTS.md in your repository and applies them as review criteria", and Anthropic's Code Review "reads two files from your repository to guide what it flags", CLAUDE.md and REVIEW.md.
The vendors are linked on billing too. CodeRabbit joined the Claude Marketplace on 27 May 2026, and "Anthropic customers can apply their existing Anthropic spend commitment toward CodeRabbit". Anthropic's marketplace page says "Claude powers CodeRabbit's context engine and review harness", and CodeRabbit's FAQ says your code is shared with "OpenAI and/or Anthropic for reviewing purposes only". A team can keep /code-review or the plugin for the moment before a push and one service on the pull request.
How to choose
| If this is true for your team | Look first at | What the pages say |
|---|---|---|
| Repositories live on GitLab, Azure DevOps or Bitbucket | CodeRabbit | CodeRabbit lists all three; Code Review lists GitHub and GitHub Enterprise Server, and for GitLab Anthropic documents a CI/CD integration in beta that GitLab maintains, and /code-review --comment; Bitbucket and Azure DevOps were not found in Anthropic's Claude Code docs index or on its Code Review page as of 11 October 2026 |
| The review should run in your own workflows or on your own servers | the Claude Code GitHub Action, or CodeRabbit self-hosted | the Action runs inside your repository's workflows; CodeRabbit self-hosts for Enterprise customers "with 500 or more user seats" |
| The bill should follow headcount, or only the reviews someone asks for | CodeRabbit for headcount; Code Review in Manual mode or /code-review for requests |
CodeRabbit bills developers who create pull requests; Manual mode bills requested reviews; /code-review counts toward normal usage |
| Your organization runs Zero Data Retention or the HIPAA configuration | CodeRabbit, the GitHub Action or /code-review, after your policy owner reads each data page |
Code Review and ultrareview are not available to those organizations |
| A tool must be able to approve, as a required reviewer | CodeRabbit |
@coderabbitai approve, which submits an approval only when the reviews.request_changes_workflow setting is enabled; Code Review's check run stays neutral, so a merge gate is a script in your CI that reads it |
| You want each candidate finding checked before it reaches the pull request | CodeRabbit, Code Review, ultrareview, or Sigma (Mnemoverse, the author's company) | CodeRabbit lists a Verification agent; Code Review describes "a verification step"; ultrareview says "every reported finding is independently reproduced and verified"; Sigma, in closed beta on GitHub by invitation, "checks potential issues and brings the evidence back to your code", and its docs say a fresh verifier "confirms, rejects or reclassifies each one", that "only confirmed candidates are verified findings" and that suspicions no verifier confirmed stay labeled separately; Sigma runs on Claude Code and OpenAI models and reviews its team's own repositories every day; its homepage takes requests through a "Request beta access" form and says "A request does not grant access automatically." |

What each vendor publishes as numbers
Anthropic's launch article of 9 March 2026 reports its own use: "We run Code Review on nearly every PR at Anthropic." On those pull requests, "Before, 16% of PRs got substantive review comments. Now 54% do.", and "Engineers largely agree with what it surfaces: less than 1% of findings are marked incorrect." The set is Anthropic's own pull requests, and its own engineers did the marking.
CodeRabbit's write-up of 28 September 2026 compares Claude models inside CodeRabbit's own pipeline, not CodeRabbit against other tools. On its 13 hardest known-bug cases, Sonnet 5.5 caught 6 of 13 issues through actionable comments, at 41.2% actionable precision, where "Actionable precision is passing actionable comments divided by all actionable comments." The post adds "Thirteen cases is a small set, and we say so throughout."
The two numbers answer different questions on different sets, so they do not belong in one column. How to read vendor benchmarks in general is the subject of "How Are AI Code Review Tools Benchmarked, and Can You Trust the Results?".
A two-week test on your own pull requests
CodeRabbit's plans page says new organizations start with a "14-day Advanced trial", and Code Review in Manual mode bills only the reviews you request on a Team or Enterprise plan. Pick ten merged pull requests from the last quarter that later needed a bug fix, so you already know what a careful reviewer should have said, and open each one again from a branch at its original commits. Let CodeRabbit review it, comment @claude review for Code Review, and run /code-review with the PR number in a terminal.
For every comment, note whether it names the known bug, whether you would have deleted it, and how many minutes it took to confirm. After two weeks you have known bugs named out of ten, comments you would delete per pull request, and cost per pull request in each vendor's own unit. That answers CodeRabbit vs Claude Code for your code, and if your code is written with Claude Code, it also shows how each reviewer does on changes from that tool.
