Free scan

See what your site tells a stranger.

Enter a URL and we will look at it the way a visitor's browser does: one request for the page, then the scripts it loads. No signup, no agent to install, and nothing your own browser would not already have fetched.

Scan sites you own or are authorized to test. See our terms and what this scan does.

What we look at, and what we will not do

Your connection

HTTPS, whether http visitors get redirected, and how long browsers are told to remember it.

Your response headers

The content policy, framing protection, referrer leakage, and what your server announces about itself.

Your cookies

Whether a session cookie can travel unencrypted, be read by scripts, or be sent from another site.

Your client code

The scripts your page loads, checked for database keys, payment keys, and model API keys that should never leave your server.

This is a passive scan

We request the page and the scripts it references, and nothing else. We do not guess at hidden paths, submit forms, try credentials, or send anything designed to break the site. Our requests identify themselves as VibeZero-Scanner in your access log. We will not scan a private or internal address, and you should only scan sites you own or are authorized to test.
