v0 security scan
Scan your v0 app for exposed keys and open databases
v0 is great for shipping a polished front end quickly. The gaps tend to be a secret left in the bundle, published source maps that reveal your code, or a backend with access rules never set.
A sample of what you might see
A secret key shipped to the browser can be used by anyone who views source. It should be rotated and moved server-side.
{ "key": "sk_live_••••••••" }Illustrative, redacted. We never store your data.
The scan reads only what a browser already downloads and checks your database access from the outside.
JavaScript and TypeScript apps today. The scan is passive and outside-in. How the scanner stays safe.
Questions
Is the scan safe for my v0 app?
Yes. Read-only and outside-in, no login, no writes. See the scanner-safety page.
What does it check?
Exposed keys in the bundle, open Supabase or Firebase databases, reachable .env, .git, and source-map files, and weak headers.
Which check do I need?
Check my live app
Scan a deployed URL for what it leaks to any visitor: exposed keys, open databases, reachable files.
