Free passive check

We fetch your page's HTML and its same-origin JavaScript bundles (max 10), then look for leaked secrets, Supabase keys and missing security headers. Nothing else: no database probing, no logins, no writes, no crawling.

Limits: 5 checks/minute per visitor, 3 checks per URL and 10 per site every 10 minutes, ~9s total, HTML ≤ 1 MB, each script ≤ 2 MB.
