Public website scanner

Know if a site is exposed — before someone else does.

One free preview per week (headers, TLS, well-known files, React2Shell). Full checks and extra scans need Pro — a new IP or VPN does not reset the preview.

Scan only sites you own or have permission to test. Terms · Free vs Pro

CVE-2025-55182

Detect unpatched React Server Components (React2Shell) with a non-executing probe plus version fingerprinting. Included in the free weekly preview.

Security headers & TLS

CSP, HSTS, clickjacking, nosniff, Referrer-Policy, Permissions-Policy, stack banners, and certificate validity.

Exposed files

.env, .git/HEAD, package.json, and server.js — reported as exposed, with secrets redacted.

Pro: critical extras

Cookies, CORS, leftover backups, JS libraries, SPF/DMARC, source maps, and CVE-2025-29927. These extra HTTP/DNS checks run only on Pro so free traffic cannot exhaust the host.
