React app built with v0? Let’s review it.
Expert code review for React apps built with v0. We find v0-specific bugs, fix React security issues, and optimize performance. From $19.
v0 issues we find in React projects
Problems specific to v0's code generation patterns when building React 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.
React issues we check for
Common React problems that affect production readiness.
XSS via dangerouslySetInnerHTML
AI tools use dangerouslySetInnerHTML to render dynamic content without sanitization, allowing script injection.
Exposed environment variables
Sensitive keys placed in NEXT_PUBLIC_ or REACT_APP_ prefixed variables, making them visible in the browser bundle.
Unnecessary re-renders
Missing React.memo, useMemo, and useCallback cause components to re-render on every parent update, degrading performance.
Unhandled promise rejections
Async operations in useEffect without proper error handling crash silently or show raw error messages.

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