4 ID Strategies

Full hash, stable (survives browser updates), weighted (fewer collisions), and cross-browser (same ID on Chrome/Firefox/Safari).

🕵

Anti-Detect Detection

Detect Multilogin, GoLogin, Dolphin Anty, Linken Sphere, Incogniton, VMLogin, and AdsPower via prototype tampering and behavioral analysis.

📈

Fingerprint Lifecycle

Track drift over time, auto-link old and new fingerprints, predict next changes, and calculate decay rates.

🤖

Bot Detection

30+ signals detecting Puppeteer, Playwright, Selenium, headless Chrome, and other automation frameworks.

🧠

Behavioral Biometrics

Profile typing rhythm, mouse movement patterns, scroll behavior, and touch characteristics.

🔒

Privacy-Aware

GDPR-friendly privacy mode, incognito-resistant mode, protocol-aware collection. You control what gets collected.
