Allow about 20 minutes as a practical setup estimate—not a measured guarantee—and assume you already have a repository and can sign in with an account that has permission to install integrations. CodeRabbit’s free offer is for public repositories, is subject to rate limits, and does not include every paid feature. GitHub Copilot Free is not a free pull-request-review option.
What “free AI pull request reviews” covers
CodeRabbit says users can sign up with GitHub or GitLab, install its integration on a public repository, and receive free reviews there. Its open-source support information also says free use is rate-limited and excludes some paid features. This is a vendor-defined offer, not a promise of unlimited reviews or free coverage for private repositories. See CodeRabbit’s pricing page and its open-source support article for the current terms.

The steps below are a suggested workflow, not a tested installation report. The actual time depends on account access, repository permissions, and any installation approval your organization requires.
Crashes, No Sound, or Screen Glitches?

- Check visibility and permissions. Confirm the repository is public and that your account can install or authorize GitHub or GitLab integrations. If you cannot approve an installation, ask a repository owner or administrator to do so.
- Sign in to CodeRabbit. Use the GitHub or GitLab sign-in option associated with the repository you want reviewed.
- Install the integration. Authorize CodeRabbit and choose the public repository for which you want reviews. Review the requested access and any organization approval prompt before proceeding.
- Open a small test pull request. Make a modest, easy-to-inspect change and open a pull request in the connected repository. This gives you a low-risk way to confirm the integration is active.
- Check for the review. Look at the pull request conversation and review activity for CodeRabbit feedback. If it does not appear, check whether the app is installed for the correct repository and whether the installation or organization approval is complete; consult CodeRabbit’s current support information for service-specific behavior.
Use the 20-minute figure as a planning estimate for this short path, not as a service-level promise. A private repository, missing permissions, or an approval queue can change the setup substantially.

Can GitHub Copilot Free review pull requests?
No. GitHub Copilot Free does not include GitHub pull request code review. GitHub’s plan page lists code review as starting with Pro, while Copilot Free’s included completions and chat are separate benefits. GitHub Docs lists Copilot Free limits of 2,000 completions and 50 chat requests; those are not pull-request-review allowances. Check the current GitHub Copilot plans and Copilot plan setup and eligibility documentation.
GitHub says most eligible individual developers can start Copilot Free without setup, but some account situations are ineligible. That easy access does not change which features the free plan includes.
If you already have a Copilot plan with code review
Request a review manually
On a pull request, select Copilot under the Reviewers section to request a review. From GitHub CLI, use one of these commands:
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errors- For a new pull request:
gh pr create --reviewer @copilot - For an existing pull request:
gh pr edit PR-NUMBER --add-reviewer @copilot, replacingPR-NUMBERwith the pull request number.
GitHub documents this manual flow in Using GitHub Copilot code review.
Configure automatic reviews
For personal accounts, GitHub documents automatic Copilot code review in Copilot settings for your own pull requests. Personal automatic review requires Copilot Pro, Pro+, or Max. Review-new-pushes and draft reviews are optional settings. For organization-managed use, administrators can configure organization settings and rulesets. Follow GitHub’s current automatic code review configuration guide.

| Question | CodeRabbit free public-repository offer | GitHub Copilot |
|---|---|---|
| Repository visibility | Public repositories on GitHub or GitLab, according to CodeRabbit; free private-repository reviews are not established by the cited offer. | Copilot Free does not include pull-request code review. GitHub code review is included with eligible paid plans. |
| How review starts | Install the integration on the selected public repository; open a pull request to check that it is active. | Request Copilot under Reviewers, or configure automatic review if your plan and account settings support it. |
| Free allowance and limits | CodeRabbit describes free reviews for public repositories, subject to rate limits; not every paid feature is included. | Copilot Free’s 2,000 monthly completions and 50 chat requests, listed by GitHub in 2026, are not review credits. Code review requires a plan that includes it. |
| Potential usage charges | The cited free offer is limited and does not establish free private-repository coverage. | GitHub says code-review model interactions can use AI Credits and agentic capabilities use Actions minutes. Code review workflows also consume Actions minutes beginning June 1, 2026. Organization-billed additional usage may arise if an organization enables review for users whose plan does not include it; admins should check billing controls. |
