Is v0 safe? How to secure your v0 app
v0 by Vercel is great at UI and increasingly full-stack — which means it can also wire up exposed data access.
v0 is safe for building interfaces, but as it generates more backend and data logic it can introduce the same exposed-key and missing-auth issues as other AI builders. Review anything that touches data or secrets.
v0 by Vercel started as a UI generator and is increasingly full-stack. For pure interfaces it is low-risk, but as v0 generates server actions, data access and auth logic, it can introduce the same exposed-key and missing-authorization issues as any AI builder. Review anything that touches data or secrets, and add security headers before launch — deployed v0 apps frequently ship without them.
