Vercel app built with Cursor? Let’s review it.
Expert code review for Vercel apps built with Cursor. We find Cursor-specific bugs, fix Vercel security issues, and optimize performance. From $19.
Cursor issues we find in Vercel projects
Problems specific to Cursor's code generation patterns when building Vercel apps.
Exposed API keys in client code
Cursor often places sensitive keys and secrets directly in client-side components or .env files without the NEXT_PUBLIC prefix distinction, making them accessible in the browser.
Missing input validation on API routes
Server actions and API routes generated by Cursor frequently accept user input without sanitization or schema validation, opening the door to injection attacks.
Unhandled async errors
Cursor wraps code in try/catch inconsistently. Failed API calls, database queries, and file operations often crash the app silently or show raw error messages to users.
Race conditions in state management
Multiple rapid state updates or concurrent API calls cause stale data, UI flickers, and inconsistent behavior — especially in forms and real-time features.
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.
