Deploy with more confidence

Check your website for exposed secrets

Enter a public page. We inspect its HTML and static, same-origin JavaScript for credential-like patterns, then show you where to look and what to do next.

One page, up to 20 same-origin JavaScript files. No login or query string.

How to use the result

A clear next step for every match

01

Review the evidence

See the matching pattern, masked text, and the public file where it appeared. Possible matches need your judgment.

02

Rotate a real credential

If a working secret was exposed, revoke or rotate it first. Then remove it from the public build and redeploy.

03

Check the new build

Rescan the same page. A missing match means it was not seen in the new scan; check the resource coverage too.

Scope of this check

This tool reads one public HTML page and static same-origin .js and .mjs references in that HTML. It does not check other routes, dynamically loaded code, source maps, API responses, login-only content, or whether a key is active. No match is not a security clearance.
