Getting started with CodeReviewr

Get AI code reviews on every pull request. No waiting for reviewers, no context switching, just fast feedback when you need it.

Visit codereviewr.app and sign in with GitHub. We use GitHub OAuth—no separate account needed.

New accounts get $5 in free credits automatically. That's enough for 10-30 reviews to see if CodeReviewr works for your workflow.

#Install the GitHub App

After signing in, go to Settings and click "Install GitHub App." Choose your personal account or organization, then select which repositories to review. Installation takes about 30 seconds.

#Automatic reviews

Create a pull request in any connected repository. CodeReviewr automatically:

Detects the PR via GitHub webhooks
Analyzes the diff using AI
Posts review comments on the PR
Reviews only new changes (incremental reviews save credits)

Reviews happen automatically—no setup required beyond installation. You can also trigger reviews manually or chat with the bot as described below.

#Chat and commands

After a review, you can interact with CodeReviewr directly in PR comments by mentioning it:

@codereviewr Why did you flag this as a security issue?

You can also trigger actions with slash commands:

/review — manually trigger a full code review
/help — see all available commands

#Review categories

Issues are categorized by severity:

Critical: Security vulnerabilities, production-breaking bugs
High: Major functionality issues, performance problems
Medium: Bugs that impact UX, technical debt
Low: Code style, minor improvements
Info: Suggestions and best practices

Each issue includes the file path, line number, and explanation. CodeReviewr focuses on meaningful problems—security, bugs, performance—not style nitpicks.

#Limitations

CodeReviewr works best for PRs under 300KB of changes. Very large PRs (generated code, massive refactors) may be skipped. Split large changes into smaller PRs anyway—it's better practice.

We currently support GitHub only. Reviews happen automatically and usually complete within seconds for small PRs.

#Managing costs

Every review costs credits based on code size. You can see exact costs in your workspace dashboard after each review.

To control spending:

Monitor token usage and costs per PR in the dashboard
Uninstall CodeReviewr from repos you don't want reviewed

Credits never expire. If you run out and auto-renewal is disabled, reviews pause automatically—we won't charge your card without your action. You can enable auto-renewal in billing settings to top up automatically when your balance drops below a threshold.

#Next steps

Create a test PR and watch CodeReviewr work. Review a few PRs, check your usage dashboard to understand costs, then adjust your workflow as needed.

If something doesn't work, check our troubleshooting guide or contact us through the website.

#Alternative: CLI reviews

Prefer reviewing code locally before pushing? Use the CodeReviewr CLI to get the same AI-powered reviews in your terminal.

npm install -g @codereviewr/cli
codereviewr auth login cr_your_token
codereviewr review

The CLI is useful for:

Pre-commit or pre-push reviews
CI/CD pipeline integration
Reviewing changes before creating a PR

See the CLI documentation for full setup and usage instructions.
