What is Klaussy Review?
Top Ranked AI Code Review Agent on ReviewBench
Klaussy Review is an AI code review agent that reviews every pull request against your repo's own conventions. Focused reviewers check correctness, security, architecture and scope; a validator then re-checks every finding and drops anything it can't confirm, so noisy false positives never reach your team.
Each review runs multiple passes with the model you choose: Claude (Sonnet by default, Opus optional), GitHub Copilot, or OpenAI. Findings are pinned inline to the exact diff line with one-click suggestions you can apply directly, and the reasoning can be expanded or collapsed.
Klaussy Review is bring-your-own-key: model usage is billed to your own Anthropic, Copilot, or OpenAI account at provider price — Klaussy never marks up tokens. Each review runs in a fresh isolated container that holds no GitHub token, and no code is stored after the review is posted. Prefer to run on your own infrastructure? The free self-hosted GitHub Action runs the same reviewer as a workflow step on your own runners, with your key.
Pricing is freemium and billed per GitHub organization or account, not per seat: Free ($0) with monthly review limits, Personal ($15/month, up to 500 reviews) and Team ($49/month, up to 1,500 reviews) with a 7-day free trial, plus Enterprise with custom limits.

Klaussy Review FAQs
Does Klaussy Review see my code?
Only to review it. Each review runs in an isolated, throwaway container that never holds a GitHub token, and no code is stored after the review is posted. You can also self-host the free GitHub Action on your own runners.
Who pays for the AI models?
You do, directly. Klaussy Review works with your own key: model usage is billed to your Anthropic, GitHub Copilot, or OpenAI account at their own prices. Klaussy never marks up token usage; the subscription only covers the app itself and is billed per organization or account, not per seat.
Is there a free plan?
Yes. The free tier includes 20 public-repo reviews and 5 private-repo reviews per month (up to 5 per day, 3 at a time). Paid plans include a 7-day free trial, which requires a card.
