Vercel app built with Claude Code? Let’s review it.
Expert code review for Vercel apps built with Claude Code. We find Claude Code-specific bugs, fix Vercel security issues, and optimize performance. From $19.
Claude Code issues we find in Vercel projects
Problems specific to Claude Code's code generation patterns when building Vercel apps.
Over-permissive CORS configuration
Claude Code sometimes sets CORS to allow all origins during development and forgets to restrict it for production, allowing any website to make API requests.
Missing rate limiting
API endpoints are generated without rate limiting, allowing attackers to brute-force auth endpoints or abuse expensive operations.
Over-engineered abstractions
Claude Code creates multiple layers of abstraction, generic utilities, and design patterns for simple problems — making the code harder to understand and maintain.
Edge cases in complex logic
While Claude handles the main flow well, complex conditional logic sometimes has edge cases that produce incorrect results with unusual inputs.
Vercel issues we check for
Common Vercel problems that affect production readiness.
Missing environment variables
Variables set locally but not configured in Vercel, causing runtime crashes in production that didn't happen during development.
No security headers
Missing Content-Security-Policy, X-Frame-Options, and other headers that protect against XSS, clickjacking, and content injection.
Serverless function timeouts
API routes that take too long hit Vercel's timeout limits, causing 504 errors for users.
Cold start latency
Serverless functions have cold start delays that make API responses slow after periods of inactivity.
