Production-ready v0 apps

v0 generates full Next.js applications with shadcn/ui components, server actions, and Vercel deployment - from a single prompt. But generated code does not equal production code.

We assess your v0 project for server/client boundary leaks, unprotected routes, missing security headers, and Next.js misconfigurations that could expose your users.

// Common issues we find in v0 apps

[CRITICAL]Sensitive data in client components instead of server

[CRITICAL]API keys in NEXT_PUBLIC_ variables exposed to browser

[HIGH]Missing or misconfigured middleware for auth routes

[HIGH]Unprotected server actions callable from client

[MEDIUM]No input sanitization on form submissions

[MEDIUM]Missing CSP, HSTS, and X-Frame-Options headers

Why v0 apps need quality assurance

v0 has evolved from a UI component generator into a full application platform - with Git integration, a VS Code-style editor, database connectivity, and agentic workflows. It generates multi-page Next.js apps with routing, shared layouts, and navigation.

The challenge is the server/client boundary. Next.js App Router introduces complexity that AI often gets wrong - sensitive data in client components, unprotected server actions, and NEXT_PUBLIC_ variables leaking secrets to the browser. We catch these before your users do.

What We Check

Next.js + Vercel-specific assessment for v0 applications

Component Security

XSS risks in generated React/Next.js components, unsafe dangerouslySetInnerHTML, client-side injection vectors, and prop validation.

Server/Client Boundary

Data leaks between server and client components, exposed server actions, and unsafe data serialization across the boundary.

Next.js Configuration

App Router patterns, middleware setup, route protection, environment variable exposure, and ISR/SSR security.

Vercel Deployment

Edge function security, serverless config, CSP headers, CORS policies, and domain/DNS hardening for production.
