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.

What v0 apps commonly leak
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].
