CodeRabbit vs Greptile
A neutral head to head on how each reviews a pull request, what each stores, what each costs, and what neither of them records.

Both are AI pull-request reviewers. The difference that matters is what they read: CodeRabbit reviews the diff with context it fetches; Greptile reviews the diff against a full index of your repository. That one design choice drives accuracy, data retention, and price.
At a glance
| CodeRabbit | Greptile | |
|---|---|---|
| Capture model | The pull request diff plus context it fetches | A persistent index of the whole repository plus the diff |
| Platforms | GitHub, GitLab, Bitbucket, Azure DevOps | GitHub, GitLab |
| Data retention | Caches encrypted code; stores vector representations; code shared with OpenAI and/or Anthropic for review | Stores customer code on an encrypted filesystem plus embeddings until access is revoked; OpenAI and Anthropic APIs |
| Training on your code | No | No |
| BYOK | Not on the public pricing page | Yes, "bring your own LLM" |
| Self-hosting | Enterprise | Enterprise option |
| Free tier | Public repositories, forever | 50 credits per month, one developer |
| Paid (checked 2026-08-22) | Pro $24/user/month annual; Pro Plus $48 | Pro $30/seat/month with 50 credits; $1 per extra credit |
| Compliance | SOC 2 (see vendor) | SOC 2 Type II |
How each reviews a pull request
CodeRabbit runs on every PR, posts a summary, a walkthrough, and line comments, and lets you tune behaviour with a YAML config and path filters. It is strongest at coverage: it will say something about every change, consistently, across four Git hosts.
Greptile indexes the repository first, then answers "what does this diff break elsewhere". That is where it earns its credits: cross-file regressions, callers you forgot, conventions established in another package. It bills per review (one credit for a standard review, three for a deeper one).
Data and privacy
This is the real fork in the road. Greptile's security page is explicit that it stores your code and embeddings on its servers until you revoke GitHub or GitLab access. CodeRabbit's FAQ says it caches encrypted code and stores vector representations, and that code is shared with model providers for review only. If "our code must not be stored by a vendor" is a hard line, neither fully clears it, but Greptile's index is the larger footprint by design. Greptile lets you bring your own model key, which changes who sees prompts but not who stores the index.
Pricing
CodeRabbit is per user per month; Greptile is per seat plus per review. A team of ten doing 40 reviews a week lands around $240 per month on CodeRabbit Pro (annual) versus $300 plus overage on Greptile, where 50 included credits per seat may or may not cover 16 reviews per person per month. Run your own numbers; both publish the formula.
What CodeRabbit does better
Breadth of hosts, a free tier for open source, and the most mature comment controls. If you want one reviewer across GitHub, GitLab, Bitbucket, and Azure DevOps, it is the only one of the two that does that.
What Greptile does better
Cross-file understanding and BYOK. If your bugs are "this change is fine locally and wrong globally", the index pays for itself.
What neither records
Both start from the pull request. Neither knows the order of commits, what the author tried and reverted, which decision was made on purpose, or which risk was noticed and left. They produce an opinion about the final diff.
PatchArc records that missing part: a CLI observes your commits while you work, you record decisions and risks in one line each, and patcharc stop seals a deterministic six-section review into an Ed25519-signed capsule that anyone can verify offline. It does not comment on code. Teams use it under either reviewer so that the bot's comments and the human's context arrive together on the PR. See PatchArc vs manual PR descriptions for how the record maps onto a PR.
Frequently asked questions
Which is more accurate, CodeRabbit or Greptile?
Neither publishes an independent benchmark. The structural difference is that Greptile reads a full repository index, so it is better positioned for cross-file issues; CodeRabbit reviews the diff with fetched context, so it is consistent and fast. Try both on the same ten pull requests.
Which stores my code?
Both store something. Greptile stores your code and embeddings on an encrypted filesystem until access is revoked. CodeRabbit caches encrypted code and stores vector representations of code. Both say they do not train on it.
What are Greptile credits versus CodeRabbit seats?
CodeRabbit charges per user per month. Greptile charges per seat with 50 review credits included and $1 per additional credit; a standard review is one credit.
Can I use both?
Yes; they post independently on the same PR. Most teams find two reviewers noisy and pick one.
Does either one verify what the author claims in the description?
No. Both reason about the diff. A signed PatchArc capsule is the only artifact in this comparison whose integrity a reviewer can check offline.
