Short Answer
v0.dev gives you the primitives for a secure app (Supabase, managed auth, hosting), but every real-world v0.dev breach we track comes from missed configuration — not missing platform features. Secure-by-default it is not.
Detailed Answer
What v0.dev gives you out of the box
v0.dev by Vercel generates beautiful React components from natural language descriptions. While the generated code is functional and well-structured, AI-generated code can sometimes include patterns that introduce security vulnerabilities, especially when handling user input or fetching data.
What v0.dev leaves to you
When you integrate v0 components into a full application, security becomes your responsibility. The generated components need proper input validation, output encoding, and secure data handling practices. Without these safeguards, your application could be vulnerable to cross-site scripting (XSS), injection attacks, and data exposure.
The security gaps that actually appear in v0.dev apps
- **XSS via dangerouslySetInnerHTML** — AI may suggest React patterns that render unsanitized user content.
2. **Missing Input Validation** — v0 generates UI but not server-side validation logic.
3. **Placeholder API Calls** — Generated code may include placeholder URLs or fake endpoints.
Platform security is strong where v0.dev controls the stack. The gaps above all sit in the application layer — where v0.dev's guarantees end and yours begin.
Verdict
v0.dev can be run securely. Treat "is v0.dev secure" as a deployment-time question, not a platform question: run a security scan, verify Row Level Security (RLS) policies are configured, and close the specific gaps above. Platforms with better defaults (e.g. enforced Row Level Security) would reduce the work — but none of them make scanning unnecessary.

Expert Perspectives
“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.”

Is v0.dev secure enough for production?
Yes — once verified. The platform layer handles infrastructure reliably; the application layer (access controls, secrets, auth) is where production readiness is won or lost. Verification is a scan + manual review of Row Level Security (RLS) policies, not a vibe check.
What percentage of v0.dev apps have security issues before review?
Based on the breaches we track and community reporting, the majority of v0.dev apps deployed without a pre-launch scan have at least one critical or high-severity finding. The #1 recurring finding is "XSS via dangerouslySetInnerHTML". This is not unique to v0.dev — it's the base rate for AI-assisted development — but it means the default state of a shipped v0.dev app is "unverified."
Does v0.dev itself have security certifications (SOC 2, ISO 27001)?
Platform certifications from v0.dev apply to the v0.dev infrastructure — not to your app built with v0.dev. Even if v0.dev is SOC 2-compliant, your app can still leak data through misconfigured Row Level Security (RLS) policies, exposed secrets, or missing access checks. Compliance for your app is a separate effort; the platform's certifications are necessary but never sufficient.
