Platform
v0 by Vercel
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.
Why it matters
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.
