Vercel app built with v0? Let’s review it.
Expert code review for Vercel apps built with v0. We find v0-specific bugs, fix Vercel security issues, and optimize performance. From $19.
v0 issues we find in Vercel projects
Problems specific to v0's code generation patterns when building Vercel apps.
No backend or API integration
v0 generates frontend components only. There's no database connection, API routes, authentication, or server-side logic — all of which need to be built separately.
Static mock data instead of real data
Components use hardcoded mock data for display. Connecting them to real APIs requires significant additional work to handle loading states, errors, and data fetching.
Components not connected to state
Interactive elements like forms, filters, and toggles look correct but don't actually do anything. State management needs to be wired up manually.
Accessibility gaps
While v0 uses shadcn/ui (which has good a11y defaults), custom components sometimes miss ARIA labels, keyboard navigation, and focus management.
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.

Frequently asked questions
Can you review Vercel code generated by v0?
Yes. We regularly audit Vercel projects built with v0 and understand the specific patterns and issues it introduces. Our review covers security, performance, and deployment readiness.
What Vercel issues does v0 typically create?
Common issues in v0-generated Vercel code include: no backend or api integration, static mock data instead of real data, components not connected to state. Combined with Vercel-specific concerns like missing environment variables and no security headers.
How do I make my v0 Vercel project production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For v0-built Vercel projects, the typical path is: fix security gaps, address Vercel-specific performance issues, then configure deployment. We provide a fixed quote after the audit.
How much does it cost to review v0-generated Vercel code?
Our code audit starts at $19 and covers security, performance, architecture, and deployment readiness. For fixes, our Fix & Ship plan is $199. Larger projects get a custom fixed quote — no hourly billing or surprises.
