For v0 users

Is your v0 app secure?

Vercel v0 generates production-ready React components. But AI-generated code often ships with hardcoded API keys, missing CSP headers, and injection vulnerabilities.

Scan your v0-built app or paste code — free, no account needed.

What v0 apps commonly leak

Hardcoded OpenAI, Stripe, Supabase, and GitHub API keys
Missing Content-Security-Policy headers — XSS wide open
Environment variables committed to client-side code
Insecure cookie flags (no HttpOnly, no Secure)
CORS misconfigurations from AI-suggested defaults
Exposed .env files and configuration backups
Server info leakage (version numbers, tech stack)
InnerHTML XSS from AI-generated JavaScript patterns

Common questions

Is v0-generated code less secure?

v0 generates from training data that includes insecure patterns. It doesn't enforce CSP, cookie flags, or secret management. The scanner catches what gets missed.

Does scanning my v0 app cost anything?

No. First scan is free. Sign up for 3 scans/day plus AI fix prompts.

Can I scan my Vercel deployment?

Yes. Paste your `*.vercel.app` URL and the scanner checks headers, secrets, configs, and injection vectors.

Can I scan before deploying to Vercel?

Yes. Use Code mode to paste your v0-generated code before running `vercel deploy`.

What if my API key is exposed?

Secrets are auto-redacted in stored results. Raw keys become [REDACTED].
