Security & Trust

Mixed Content Checker

Find every insecure HTTP resource hiding on an HTTPS page before the browser blocks it, or a visitor sees the warning.

What it checks

  • ✓Scans scripts, stylesheets, images, iframes, and inline styles for HTTP references on HTTPS pages
  • ✓Separates active content (scripts, CSS, iframes -- full compromise risk) from passive content (images -- lower risk, still flagged)
  • ✓Detects whether your CSP already mitigates the issue via upgrade-insecure-requests
  • ✓Lists every distinct offending host, so you know exactly what to fix and where
