This ones my fave: https://amiunique.org/fingerprint

It shows the percentages of people who use your same browser features (called similarity ratios), and can determine whether you're unique in their dataset. Can help for tweaking browser settings to try to make yourself not unique.

all trackers hate this one trick

Vibe coded af, how has nobody spotted this. The website swears the text was written by a human, and either they have contracted chronic GPT-virus or are an LLM

edit: this is made by Rise Up Labs which is an ai psychosis company

"We know your IP address". No kidding, that's how IPv4 works, even if the browser wasn't ~~leaking~~ offering it.

And yet here they are showing me their webpage in darkmode 😒

Really interesting and slightly scary, thanks for sharing!

I prefer https://www.deviceinfo.me/

Funny how websites can read the gyroscope. It can also be used as a microphone. https://crypto.stanford.edu/gyrophone/

So a prettier and minimal version of https://coveryourtracks.eff.org/ ?

Well too bad!

Well they tried

This post helped me discover that my SurfShark VPN built-in kill switch does not work within the Android app. My home IP was showing.

I turned kill switch on at the OS level and my IP was correctly showing the VPN IP.

Your screen is 360 by 640 pixels, rendered at 4x density — which means it is almost certainly a recent, high-end display

GUESS AGAIN, IDIOTS!

Your device carries these typefaces, of the seventeen commonly probed by fingerprinting checks. The specific combination of fonts on your device is nearly unique — like a fingerprint made of letters

What the fuck why is my browser telling random websites what fonts I have installed? Shouldn't that be completely irrelevant to everyone except me and my particular device?

I'm glad it acknowledges explains the impacts of anti-fingerprinting measures. I've seen some others assume that a random canvas is unique rather than one of the many people randomising it the same way, leading to a false "unique" assessment.

Your browser appears to be returning the viewport in place of the real screen — anti-fingerprinting at work. The substitution is itself distinctive.

Your browser masked your graphics processor. Firefox and Safari have started returning generic strings — "Mozilla", "Apple", "or similar" — instead of the real renderer. The fact that yours did so tells us, with reasonable confidence, which browser you are running. The mask is also a fingerprint.

I definitely have misleading information on there, which is great, but I probably need more.

Great news. My VPN is working!

Your finger moved 899 times.. what????

This volume requires JavaScript. That is part of the point — your browser is what is being read.

Looks like I'm safe

I found it interesting that it knows my battery level and current orientation of the phone.

Time to start installing and uninstalling random fonts everyday.

it didnt catch much stuff and a lot was wrong lol

Well then I am glad that it got most of it wrong. I don't even put thaat much emphasis on fingerprinting countermeasures. Apparently, using Firefox in a private tab is enough.

Opend it in Tor Browser inside a Whonix dispVM inside Qubes OS it got nothing on me

which means it is almost certainly a recent, high-end display

lolno

why would my browser share a list of fonts?

Scary
