Next.js app built with Claude Code? Let’s review it.
Expert code review for Next.js apps built with Claude Code. We find Claude Code-specific bugs, fix Next.js security issues, and optimize performance. From $19.
Claude Code issues we find in Next.js projects
Problems specific to Claude Code's code generation patterns when building Next.js 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.
Next.js issues we check for
Common Next.js problems that affect production readiness.
Unprotected API routes
Next.js API routes and server actions without authentication checks, allowing anyone to call them directly.
Server action data exposure
Server actions that return sensitive data to the client or don't validate user permissions before modifying data.
Incorrect middleware configuration
Auth middleware that doesn't cover all protected routes, uses wrong matchers, or can be bypassed with URL manipulation.
Missing ISR/SSG configuration
Pages that should be statically generated are server-rendered on every request, causing unnecessary load and slower responses.
