GILD verdict
Choose CodeRabbit when review is the job, for its wider Git platform coverage, reviews before the pull request, and rules you tune per path.
Choose Seer's review when the team debugs production with Seer, since review comes at the same per-contributor price and keeps diagnosis and review with one vendor. Teams running both should compare comments that led to a change on the same repository, using CodeRabbit's acceptance-rate dashboard as one side.
Where your code lives decides most of this. Seer's Code Review predicts errors in each change on GitHub.com and GitLab.com only, inside the per-contributor price that also covers Autofix and Seer Agent. CodeRabbit reviews on every major Git platform, with path instructions and IDE and CLI reviews.
Choosing between CodeRabbit and Seer
Choose CodeRabbit if
- Repositories are on Azure DevOps, Bitbucket, GitHub Enterprise Server, or self-managed GitLab.
- You want reviews before the pull request exists, in VS Code-compatible editors or the CLI, and review rules written per path.
- You want PR summaries and unit test generation alongside review findings, or you need self-hosting.
Choose Seer if
- You already run Sentry and want one subscription for error diagnosis, fixes, and review.
- You want a GitHub check that reports success when Seer finds nothing and neutral when it flags errors.
- The people who open pull requests are the same people Sentry would count as active contributors for Autofix anyway.
Side by side
| Dimension | CodeRabbit | Seer |
|---|---|---|
| Team priceList prices in US dollars. | Essentials US$24, Team US$48, or Advanced US$72 per developer per month billed annually; US$30, US$60, or US$90 month to month | US$40 per active contributor per month, covering Code Review, Autofix, and Seer Agent, plus a Sentry Team or Business plan |
| Who is billed | Developers assigned a seat | On GitHub, anyone who opens 2 or more pull requests in a month in a Seer-enabled repository, excluding accounts marked [bot]; on GitLab, every group member counts |
| Review limits | 5, 8, 10, or 12 pull request reviews per developer per hour by plan, then usage-based reviews if enabled | Sentry describes the price as unlimited use |
| Git platforms | GitHub, GitHub Enterprise Server, GitLab cloud and self-managed, Azure DevOps, and Bitbucket Cloud and Data Center | GitHub.com and GitLab.com only |
| When it reviews | Pull requests on the Git platform, plus local changes in VS Code-compatible editors and the CLI | When a pull request is ready for review and on each commit after that; drafts are skipped, and @sentry review runs it on demand |
| Code sent and training | Code shared with OpenAI and Anthropic for review; not used for training on private repositories, while the privacy policy reserves training on open-source repositories | File names, code diffs, and pull request descriptions sent to the AI provider; not used to train generative AI models unless you opt in |
| Self-hosting | Enterprise plan | Not available: self-hosted Sentry does not include Seer |
What practitioners report, side by side
Each product's figures come from its own practitioners, for the group you pick.
Overall signal
CodeRabbit reads +16 and Seer +11, each from its own practitioners. CodeRabbit: 23 positive, 14 negative of 46. Seer: 10 positive, 6 negative of 29.
The score counts the authors from leaders and teams that take a side, one vote each with their latest view, and is how far positive votes lead negative ones, per 100 votes, so CodeRabbit's +16 rests on votes split 21 positive, 9 mixed and 14 negative and Seer's +11 on 9, 13 and 6.
A lead of a fifth of the votes reads positive and a lead of half strong positive, with the same lines below zero. The dots show each source, positive, mixed, negative. Run a pilot on live pull requests to measure which comments engineers act on and which they dismiss.
Footprint on the Agentic Software Development stack
They differ on six of 12 layers. CodeRabbit owns one that Seer does not, and Seer owns two that CodeRabbit does not. Coverage is each product's placement on this stack, as its product page shows it. Core is a job the product owns; Supports and Touches are jobs it helps with. Coverage says nothing about how well a product does them.

What practitioners praise
Among leaders and teams, CodeRabbit alone has three praise themes that reach 5 sources from 3 authors. Real Bug Catches and PR Summaries & Walkthroughs lead, at 12 of 12 and 4 of 5. Code Review Catches reaches 5 sources from 3 authors only for Seer, at 10 of 16. CodeRabbit needs a pilot on the same pull requests before you choose on it.
| Praised for | CodeRabbit | Seer |
|---|---|---|
| Real Bug Catches | 12 of 12 | Not a theme in its sources |
| PR Summaries & Walkthroughs | 4 of 5 | Not a theme in its sources |
| Configurable Review Rules | 4 of 8 | Not a theme in its sources |
| Code Review Catches | Not a theme in its sources | 10 of 16 |
Each count is the sources that praise a theme, or raise it as a concern, out of those that discuss it. A row pairs the two products when both carry a theme under the same or an equivalent name.
A count ending in "so far" has under 5 sources from 3 authors among leaders and teams. "Not a theme in its sources" means GILD found no theme of that name in that product's sources.
What practitioners raise as concerns
Among leaders and teams, CodeRabbit alone has three concern themes that reach 5 sources from 3 authors. Comment Noise and Wrong or Overstated Findings lead, at 18 of 23 and 4 of 6. Platform & Setup Limits and Wrong Findings reach 5 sources from 3 authors only for Seer, at 6 of 6 and 5 of 6. CodeRabbit needs a pilot on the same pull requests before you choose on either.
| Raised as a concern | CodeRabbit | Seer |

| Wrong or Overstated Findings | 4 of 6 | Not a theme in its sources |
| Rate Limits & Seat Cost | 4 of 8 | Not a theme in its sources |
