Description
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.Link: https://deviceprint.io

Could you build this?
Partial A basic browser fingerprinting script can be vibe-coded, but an enterprise-grade, evasion-resistant device identifier requires deep telemetry research and ongoing counter-anti-fingerprinting tuning.
What it would actually take: A production-grade device fingerprinting solution (like FingerprintJS Pro) involves collecting dozens of browser signals (Canvas, WebGL, AudioContext, hardware concurrency, fonts, WebRTC) coupled with server-side machine learning models to detect spoofing, virtual machines, and bot scrapers. The difficult part is maintaining high entropy and stability across browser updates while actively bypassing privacy sandboxing measures implemented by Chromium, Safari, and Firefox.
Discussion
20 comments analyzed.
Concerns raised: False positive visit counts and location data showing hundreds/thousands of incorrect visits, Inconsistent results across browser tabs and profiles, Inaccurate browser and OS detection, Privacy issue: displaying other visitors' IPs and locations, Fingerprint collisions causing over-counting in edge cases

Nobody's really built a vertical saas tool for Insurance yet.
