Is your v0 app secure?
v0 generates polished Next.js front-ends and full-stack flows. The UI is excellent — but generated Next apps often leak server secrets to the client and skip auth on server actions. Opviva is the agent that checks, proves, and fixes your v0 app.

Common security gaps in v0 apps
Secrets leaked to the client
Server-only secrets get prefixed NEXT_PUBLIC_ or read in client components, shipping them in the browser bundle.
Unprotected server actions & route handlers
Generated server actions run without auth or authorization checks, so any caller can trigger privileged operations.
Missing security headers
CSP, HSTS, and cookie hardening are absent unless added by hand.
The agent that checks, proves, and fixes your v0 app
- Tell it your app's URL — the free scan grades your live app 0–100 in seconds, no code access needed.
- Connect GitHub and it reasons about your repo for deeper, fix-ready findings.
- It proves each exploit is real on the Evidence Canvas, then opens the fix as a pull request you approve.
- It keeps watching after launch — continuous monitoring and uptime so new issues get caught and closed.
v0 security — ask the agent
Is my v0 app secure?
Generated Next.js apps commonly leak secrets to the client and ship server actions without auth. Tell Opviva your app's URL and its free scan checks your live deployment and grades it in seconds.
How do I know if v0 leaked my environment variables?
Opviva's agent scans your live bundle for client-exposed env vars and secrets — paste the URL, no code access needed.
Can Opviva fix v0 / Next.js security issues?
Yes. The agent proves the issue, then opens reviewed PRs that move secrets server-side, add auth to server actions, and set security headers.
How do I secure my v0 app?
Start with a free Opviva scan of your live v0 app — it grades you 0–100 and lists exactly what's exposed. Then connect GitHub so Opviva can open reviewed pull requests that move secrets server-side, add access control, and set security headers, and keep monitoring after launch.
Is it safe to launch a v0 app to production?
Not until it's checked. AI-generated apps frequently ship with exposed keys, missing access control, and no security headers. Run Opviva's free scan first (no signup), fix what it finds, and turn on continuous monitoring so new issues are caught automatically.
