Lucent — Browser Audit

Audit your browser security, inspect JavaScript behavior on any website, and analyze GDPR compliance — all locally.

BROWSER HEALTH CHECK Get an instant security score (0–100) for your Chrome configuration. Browser Audit checks 16 security and privacy settings against a maintained baseline: • Is Chrome up to date? • Are third-party cookies blocked? • Is DNS over HTTPS active? • Is Safe Browsing in Enhanced mode? • Are there malicious extensions installed? • Do your extensions have excessive permissions? • How unique is your browser fingerprint? • Is WebRTC leaking your real IP? Each failed check shows exactly what to fix and links directly to the right Chrome settings page. SCRIPTSPY Inspect what JavaScript is actually doing on any website — in real time. See which scripts make network requests, read cookies, track your mouse, or use fingerprinting techniques to identify you without cookies. For each script, ScriptSpy shows: • Risk score (0–100) with explanation • Whether it's first-party or third-party • Network destinations contacted • Fingerprinting techniques used (canvas, WebGL, audio, navigator, fonts) • Input and mouse event listeners Click "View script ↗" to open the source in Chrome's built-in viewer.
