How Mystery Tag Works
Everything runs client-side. No page content ever leaves your browser.
Technology Fingerprinting
Signature-based scanning of DOM, global namespaces, network hints, and headers to detect frameworks, CMSs, and analytics — instantly.
AI Builder Signatures
Recognises pages built with AI-first tooling — Lovable, v0, Bolt, Cursor — through a curated pattern library updated with each release.
Local Data Flow
All analysis executes in the extension sandbox. Findings live in your browser storage and disappear when you clear them.
