CodeRabbit vs Greptile: How They Actually Differ
CodeRabbit fits small teams that want line-level PR review across multiple Git hosts, including a free open-source tier. Greptile fits teams on GitHub or GitLab that want reviews grounded in the whole repository and are willing to pay. The core difference is review scope: diff lines versus whole repo.
Compiled 2026-08-27 from our catalogue entries for CodeRabbit and Greptile.
The short answer
- Pick CodeRabbit if
- You need PR review that works across GitHub, GitLab, Bitbucket, and Azure DevOps, or you maintain an open-source repo that qualifies for the free tier.
- Pick Greptile if
- Your code lives on GitHub or GitLab and you want review comments that reason about the whole repository and cross-file relationships rather than only the diff.
- Cheapest way in
- CodeRabbit: the free tier for open-source repositories. Greptile: the Starter Free plan listed in its verified plans. Both have a no-cost entry point on paper.
- What we could not compare
- Review accuracy, language coverage, latency, support quality, and the actual behavior of very large PRs on Greptile are not recorded in the fact sheet.
CodeRabbit and Greptile are both AI code reviewers in the AI Coding Agents category, and both post comments directly onto pull requests on the connected Git host. Both are listed with web and CLI platforms and both target the PR-review step rather than the editor. The fact sheet for CodeRabbit calls it the broad-platform PR reviewer; the sheet for Greptile calls out its whole-repo approach.
The practical split for a solo founder or small team is platform coverage and review scope. CodeRabbit lists four Git hosts, including Azure DevOps, and offers a free tier for open-source repositories. Greptile lists GitHub and GitLab, has no free tier, and aims its review at the entire repository so it can reason about cross-file relationships and project conventions rather than just the changed lines.

Where CodeRabbit is the better fit
- Posts contextual review comments tied to specific diff lines, not just file-level summaries.
- Supports GitHub, GitLab, Bitbucket, and Azure DevOps, and offers a free tier for open-source repositories.
- Has a wider plan ladder on file, including Pro, Pro Plus, Enterprise, CodeRabbit Security, a Slack agent, and a CLI credit option.
Where Greptile is the better fit
- Analyzes the entire repository context rather than only the changed lines in a pull request.
- Uses large language models to reason about cross-file relationships and project conventions during review.
- Includes a Starter Free plan alongside Pro and Enterprise, and posts review comments directly onto PRs in the connected Git host.
Which one should you pick?
It is the only one of the two on file that lists all four hosts, which matters if your repos are split across providers.
The fact sheet lists a free tier for open-source repositories; Greptile is described as paid only with no free tier.
Its stated edge is whole-repo context and reasoning about cross-file relationships, which is more useful than line-level diff checks on a single repo.
Greptile is paid-only and positioned around repo-wide reasoning, which is a closer fit if budget is not the constraint and the team is on GitHub or GitLab.
Frequently asked questions
- Do both tools post comments directly on pull requests?
- Yes. The fact sheet describes both as posting review comments onto PRs in the connected Git host.
- Does Greptile have a free tier?
- Yes, a Starter Free plan is listed in its verified plans. The Greptile section also says the product is paid and has no free tier, so treat the Starter Free entry as the only no-cost option on file.
- Which Git hosts does CodeRabbit support?
- GitHub, GitLab, Bitbucket, and Azure DevOps are listed in the CodeRabbit fact sheet.
- Can Greptile review Bitbucket or Azure DevOps repos?
- The fact sheet for Greptile only lists GitHub and GitLab for integration; Bitbucket and Azure DevOps are not recorded for Greptile.
- What happens on very large pull requests?
- For CodeRabbit, the fact sheet notes that review depth depends on diff size and very large PRs can be truncated. For Greptile, behavior on very large PRs is not recorded.
- Are these in-editor assistants?
- No. Both fact sheets describe them as PR-review tools and explicitly distinguish them from in-editor assistants.

Limits on file: Review depth depends on diff size — very large PRs are truncated.; Custom rule configuration takes time to tune for noise level. CodeRabbit is an AI code-review bot that posts inline comments on every pull request across GitHub, GitLab, and Bitbucket. Its strength is line-level, multi-platform review: contextual comments tied to specific diff lines rather than file-level summaries, across GitHub, GitLab, Bitbucket, and Azure DevOps, with a free tier for open-source repositories. It fits teams that want automated review on every PR, especially across mixed Git hosts. Two caveats: review depth depends on diff size — very large PRs get truncated — and the custom rule configuration takes time to tune down noise. It's the broad-platform PR reviewer next to Greptile's whole-repo approach, distinct from the in-editor assistants. ## Greptile (/tools/greptile) Tagline: AI-powered code review that comments on PRs by understanding the entire codebase, not just the diff. Category: AI Coding Agents Pricing model: paid Starts at: Pro — $30 /seat/month Platforms: web, cli Public repo: none listed Docs: none listed Verified plans (read 2026-08-21): Starter Free | Pro $30 /seat/month | Enterprise Custom pricing Strengths on file: Analyzes the entire repository context rather than only the changed lines in a pull request.; Posts review comments directly on pull requests in the connected Git host.; Integrates with GitHub (and GitLab) repositories to ingest and review code.; Uses large language models to reason about cross-file relationships and project conventions during review. Limits on file: No free tier is offered; access requires a paid plan.; Code must be hosted on a supported Git provider, creating dependency on that integration. Greptile is an AI code reviewer that comments on pull requests by reading the whole codebase, not just the diff. Its edge is whole-repo context: it analyzes the entire repository rather than only the changed lines, reasoning about cross-file relationships and project conventions, and posts its comments straight onto PRs in your Git host (GitHub and GitLab). It's for teams that want reviews aware of the broader codebase, not line-by-line diff checks. Caveats: there's no free tier — it's paid only — review runs only through the web platform with no IDE plugin or CLI, and your code has to live on a supported Git provider. It's a PR-review tool like CodeRabbit, distinct from the in-editor assistants.
