Honestly I was surprised about this. It accurately got my GPU and specs without asking for any permissions. I didnt realize I was exposing this info.

Why were you surprised?

You can check out here how it does that: https://github.com/AlexsJones/llmfit/blob/main/llmfit-core/s...

To detect NVIDIA GPUs, for example: https://github.com/AlexsJones/llmfit/blob/main/llmfit-core/s...

In this case it just runs the command "nvidia-smi".

Note: llmfit is not web-based.

How could it not? That information is always available to userspace.

I run LibreWolf, which is configured to ask me before a site can use WebGL, which is commonly used for fingerprinting. I got the popup on this site, so I assume that's how they're doing it.

Do you mean the OPs website? Mine's way off.
