Third-Party Surface Auditor
Enter a URL to observe third-party origins, external scripts, iframe/CDN references and SRI signals. Service categories come from AC's explicitly heuristic known-service subset; there is no authoritative tracker dataset, legal privacy verdict or browser network-waterfall claim. Dynamic requests are outside scope.
The server reads public HTML only. JavaScript is not executed, private areas are not accessed and results are not stored.
Classification is not a verdict.
Origin observation is high-confidence evidence. Service category is a heuristic interpretation from AC's own curated known-service subset. No claim is made that DuckDuckGo Tracker Radar or another authoritative tracker dataset is used; an unknown origin does not mean a bad origin. Browser-based execution is required for dynamic requests.
