FingerprinterJS

A tiny JavaScript library for browser fingerprints. Lightweight JavaScript library (with full TypeScript support) for generating unique browser fingerprints — ideal for device identification, analytics, and fraud prevention. I made FingerprinterJS, a small library with no dependencies that creates browser fingerprints from signals like canvas, WebGL, audio, fonts, userAgent, and screen info.
