I got tired of waiting days for code reviews on my PRs. So I built a tool that uses Claude AI to review every pull request automatically.
Here's how it works and what I learned building it.
The problem
Code reviews are slow. You open a PR, ping your team, wait hours (or days), and half the comments are about obvious stuff — missing error handling, weak passwords, SQL injection risks.
I wanted to automate the obvious stuff so human reviewers could focus on logic and architecture.
How it works
- Connect your GitHub repo via webhook
- Every new PR triggers Claude AI to analyze the code
- Claude posts inline comments directly on the diff within seconds
What Claude catches
- 🔒 Security issues: hardcoded secrets, SQL injection, weak crypto
- ⚡ Performance problems
- 🏗️ Architecture issues
- 💅 Code style
Tech stack
- Next.js 14
- PostgreSQL (Neon)
- Claude API (Anthropic)
- GitHub Webhooks + API
- Vercel
