I made FingerprinterJS, a small library with no dependencies that creates browser fingerprints from signals like canvas, WebGL, audio, fonts, userAgent, and screen info. It’s written in TypeScript, lets you enable/disable collectors, add custom data, and includes a simple suspicious-activity score. Would love feedback.

Not new but quite cool. Note: https://creepjs.org/ is NOT official the repo is https://github.com/abrahamjuliot/creepjs Anyone knows how fingerprinting works mathematically? what do they use? when the signals may vary even slightly, your final hash should be sufficiently accurate and stable. A simple hash won't do it. Changing IP, missing cookies/session, resizing window, TLS/SSL browser handshake, screen depth, font rendering, MTR, network latency if you want to measure, etc... any signal alone means little but as a whole mathematically what is…

Hi HN, I built DevicePrint after running into problems with duplicate accounts and unreliable cookies in my own projects. DevicePrint is a lightweight device fingerprinting tool designed for developers. It helps identify devices across sessions without relying on cookies. Use cases include fraud detection, preventing duplicate signups, and security-sensitive workflows. I'd really appreciate feedback — especially around privacy concerns or edge cases you’ve run into.

I've published an open specification for a detection method I'm calling RQ4 (Request Context Fingerprinting). It analyzes whether HTTP request headers are logically consistent with real browser behavior - not just what headers are present, but whether they make sense together given the request context.
