AI code reviews on every pull request

Install a GitHub App. Bring your Anthropic key, your OpenAI key, or both. Get detailed, context-aware code reviews from Claude and/or GPT — automatically, in minutes.

14-day free trial. $10/mo. No credit card required.

How it works

1. Install the GitHub App — Add CodeMouse to your GitHub organization or personal account. Choose which repos to connect.
2. Add your AI key(s) — Connect your Anthropic key, your OpenAI key, or both. Connect both and each PR gets reviewed by Claude and GPT in parallel. Keys are encrypted at rest (AES-256-GCM).
3. Open a pull request — CodeMouse reviews it automatically and posts detailed comments directly on GitHub.

Built for developers

• Full repo context — Reviews use the entire repository, not just the diff.
• Claude, GPT, or both — Connect one or both. When both are connected we merge the findings and drop duplicates, so you get a single consolidated review.
• Bring your own key — No AI cost markup. You pay Anthropic and/or OpenAI directly (~$0.05–0.15 per review per provider).
• Reads the room — Reviews every existing PR comment (humans, other bots, earlier CodeMouse runs) and won't repeat what's already been said. Follows up on its own threads when fixes land.
• Approves clean PRs — When the diff looks good, prior concerns are addressed, and CI is green, CodeMouse actually approves the PR.
• No throttling — Every review starts instantly. No queues, no rate limits.
• Works with any language — TypeScript, Python, Go, Rust, Java — if it's code, CodeMouse reviews it.
• Inline comments — Review comments appear on specific lines in your PR.
• Zero config — No CI pipelines, no YAML files, no build steps.

Simple pricing

$10/month with a 14-day free trial. Unlimited repositories, pull requests, and team members. No throttling — reviews start instantly. Plus your own Anthropic and/or OpenAI API usage (~$0.05–0.15 per review per provider).

Frequently asked questions

What AI models does CodeMouse use?

Your choice: Anthropic Claude, OpenAI GPT, or both — powered by your own API keys. Connect both and each PR gets reviewed by both models in parallel; we merge the findings and drop duplicates.

What happens when both models flag the same thing?

We de-duplicate overlapping comments by file, line, and semantic similarity. You get a single consolidated review — not two bots arguing on your PR.

Is my code stored?

No. Your repository is cloned temporarily to run the review and deleted immediately after.

Does it work with private repositories?

Yes. The GitHub App uses installation access tokens scoped to the repositories you grant access to.

How much does the AI usage cost?

Typically $0.05–0.15 per review per provider. You pay Anthropic/OpenAI directly — we don't add any markup.

Can I cancel anytime?

Yes. Cancel through the billing portal. No contracts, no questions asked.

Does it replace human code reviews?

No — it complements them. CodeMouse catches mechanical issues so your team can focus on architecture and design.
