CodeRabbit free tier setup for GitHub PR reviews

2026-09-22 - ABikram Mondal

What the free tier actually gives you

CodeRabbit connects to GitHub, GitLab or Bitbucket and reviews pull requests with AI. The free plan covers unlimited public and private repositories with no credit card required, according to the CodeRabbit documentation updated September 2026.

You get PR summaries on the web dashboard. Full code reviews run through the VS Code extension or CLI at limited rates. The company states the free tier works for small to medium teams with moderate pull request volume.

Rate limits sit at one PR review per developer per hour on the main pull request flow. IDE and CLI reviews allow three per hour. Each review handles up to 150 files after path filters, per the plans table in the docs.

Public repositories receive more generous open source allowances in some cases, but private ones stay at the base free numbers. No time limit appears on the free plan itself.

The catch is the hourly cap. If your team opens more than one pull request per hour per active developer, reviews queue or skip until the rolling window resets. High volume teams hit this wall quickly.

Create the account in under five minutes

Go to coderabbit.ai and sign up with a GitHub account. The process needs no payment details at any point during free tier creation.

Confirm your email if prompted. The dashboard opens immediately after verification. No trial expiration clock starts on the free plan.

Existing GitHub users see the option to install the CodeRabbit app right away. Choose the repositories you want to connect during the install flow.

Grant the necessary permissions for pull request comments and status checks. The app installs as a GitHub integration with read and write access scoped to the selected repos.

Once installed, the free tier activates automatically. You can downgrade or cancel later from the billing section if needed.

Connect repositories and set basic rules

From the CodeRabbit dashboard, select the connected GitHub organization. Pick the repositories that should receive reviews.

Leave default settings for the first run. These include automatic review on new pull requests and summary generation.

Turn on the VS Code extension if you use that editor. Search for CodeRabbit in the extensions marketplace and install it. Sign in with the same account.

The CLI option works for terminal users. Install via npm or the direct binary from the docs. Authenticate with a token generated in the dashboard.

Test the connection by opening a small pull request on one repository. Watch for the summary comment within minutes.

Run your first real review

Open a pull request with code changes. CodeRabbit posts a summary comment listing main files and suggested issues.

Switch to the VS Code extension for inline comments during your own review. The extension shows AI suggestions directly in the editor.

Use the CLI command to trigger a review on a local branch before pushing. This helps catch issues early in the workflow.

Respond to the AI comments the same way you reply to human reviewers. The system tracks conversations in the pull request thread.

Repeat for a few pull requests to see the rolling hourly limit in action. The dashboard shows remaining quota for the current window.

Stay inside the free limits day to day

Batch small changes into fewer pull requests when possible. One larger review uses the same hourly slot as a tiny one.

Schedule heavy review days around the reset times. The rolling window means activity from an hour ago frees up capacity.

Reserve full reviews for pull requests that actually need them. Use the web summary for quick checks on low risk changes.

Monitor the usage page in the dashboard. It lists reviews consumed and files processed per developer.

Indian developers working on side projects or small teams report the limits feel reasonable for one or two active contributors, based on public discussions around the September 2026 docs.

When the free tier stops being enough

Teams with four or more developers opening pull requests regularly will notice the one per hour cap. Reviews start queuing during peak hours.

Paid plans start at nineteen dollars per user per month for unlimited reviews and extra features like custom rules. The company removed older legacy plans in June 2026 and moved users to current tiers.

Open source maintainers can still request higher allowances on public repositories through the OSS program. Private work stays on the base free limits.

If you exceed the cap often, the Pro plan removes the hourly restriction and adds advanced integrations. Downgrading back to free remains available at any time from the billing menu.

Start with the free tier on your main repositories. You will know within a week whether the rate limits match your actual pull request pace.

The short version. CodeRabbit free tier gives unlimited repos and PR summaries with one review per developer per hour on GitHub, no card needed, but the hourly cap is the real limit for active teams.

If you got here because you are actually thinking about having it built properly once, instead of stitching six free tiers together and maintaining them forever, that is the work I do. I build for founders and small teams who want the thing to exist and work, not a deck about it.
