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.

Happy to answer any technical questions or discuss implementation details.
