An honest security analysis of v0.dev for developers considering it for their projects.
v0.dev by Vercel is very safe - it ONLY generates frontend UI components using shadcn/ui and React. Unlike Lovable or Bolt.new, v0 doesn't generate backends, databases, or authentication, which dramatically reduces the attack surface. Security depends on how you integrate the UI into your full-stack application.
v0.dev is inherently safer than full-stack AI tools because it only generates UI. There's no database to misconfigure, no RLS to forget, no API keys to expose. The risk comes from how YOU integrate v0 components into your backend. Review dangerouslySetInnerHTML usage and remember that all validation must happen server-side.
Understanding v0.dev security in the context of broader industry trends and research.

“There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.”
“It's not really coding - I just see stuff, say stuff, run stuff, and copy paste stuff, and it mostly works.”
Yes, v0.dev is safe for production UI components. Since it only generates frontend code using well-audited libraries (shadcn/ui, Radix), there are no database or backend security concerns. The security of your app depends on your backend integration, not v0 itself.
No, v0.dev ONLY generates frontend React/UI components. Unlike Lovable (generates full Supabase apps) or Bolt.new (generates full-stack apps), v0 focuses solely on UI. This is actually a security advantage - there's no database configuration to get wrong.
React escapes content by default, preventing most XSS. However, watch for dangerouslySetInnerHTML which v0 may suggest for rich text rendering. If present, ensure you sanitize HTML input with a library like DOMPurify before rendering.
v0 only generates UI components - no databases, no authentication flows, no API keys. Lovable and Bolt.new generate full-stack apps with Supabase/Firebase backends that need security configuration. v0's limited scope means fewer security concerns but also less out-of-the-box functionality.
v0 generates client-side form UI with basic HTML validation attributes, but this is easily bypassed. You MUST implement server-side validation for all form inputs. Never trust client-side validation alone - treat v0 form components as UI shells that need backend security.
Don't guess - scan your app and know for certain. VAS checks for all the common security issues in v0.dev applications.
