    It doesn’t seem to be very good, but don’t worry, just keep prompting Claude and I’m sure you’ll get it sorted out.

    Jokes aside, it’s cool but it’s not useful if it’s the first time I visit and I see I have 10+ past visits from all around the world… obviously this is not reliable and I wouldn’t use it for anything, much less anything serious.

      Anecdotally speaking, this is the case for most new Show HNs now :^)

        Why actually try to understand a problem space? Far easier to prompt a turd into existence, polish it up with a cliché marketing page, and collect public validation from your fellow “hackers”

      I've got 743 visits from one IP!

    AmIUnique.org has a good collection of non-cookie tracking techniques.

    I’ve visited 292 times. From Melbourne, Athens, Piraeus, Paris, Munich, Vantaa, Berlin and Kuala Lumpur. I’ve used Chrome, Firefox and Safari on both mobile and desktop.

    What’s even more impressive is I’ve made all of those visits from all of those cities in the last few minutes.

    You may have a bug.

      It also has a 99.5% confidence that it has uniquely fingerprinted me, and says I have had 677 visits to the site, including Vietnam & Sweeden...

      I think the 'unique' part of fingerprinting here isn't working unfortunately.

      You've (just) between the speed of my world tour - congratulations

    Unfortunately this is an example of how AI should not be used.

    You have to be able to understand your core technology/IP/logic - I feel that must have been significantly overlooked here.

    I love services that have not a single person as a contact/responsible for the site. /sarcasm

    It's a red flag if you hide behind a contact form with no reachability beyond that whatsoever.

    And as other said: 99.5% accuracy means you should have millions of working fingerprints, since mine and others are faulty as hell.

      Ah, but it's "Trusted by developers and security teams worldwide!"

    This reminds me of EFF's Cover Your Tracks, the rebrand of Panopticlick: https://coveryourtracks.eff.org/

    This helps you see how your browser tries to block or deflect fingerprint and trackers. I miss their "You are one of x,000 users" from the old site but it still gives a nice summary of bits of info your browser leaks and how fingerprinting basically works.

    What differentiates this from http://fingerprint.com/?

    Visited for the first time and it said I already visited 800+ times with a 99.5% accurancy - not very promising. From the code this also looks like very simple client-side fingerprinting + IP information?

  • dkindler 3 hours ago

    FYI, I'm seeing 99.5% confidence I've been to the site 62 times. I can assure you 've been there once.

    • m00dy 3 hours ago

      I think it is called false positive :)

  • pbhjpbhj 2 hours ago

    Apparently I went from Germany to UK in 29 minutes, pretty good.

    It's a 99.5% declared confidence and says it used 30+ signals.

    Assuming you've a list of VPN IP addresses, and travel times between countries, I reckon you should be able to rule out some false positives.

    Would be interested to know what the "signals" were that produced the match.

    I'm on domestic broadband in the UK (IPv4), according to dnschecker they're on a mainstream mobile provider in Germany. Could be a private tunnel, but those would be rare. Which raises the question of how the confidence rating is made.

    I like the general page presentation, a good landing page except that you'll tend to put off everyone who gets a bad result for the example. That might be turned around with something showing "if this isn't you, well done on your browser security" and maybe some compelling stats on confirmed matches from testing?

  • Oras 3 hours ago

    The aim is great, and this would be useful for many use cases, especially when buying traffic (ads).

    But as others mentioned, it is far from being accurate. I got the same as others, multiple visits from multiple countries.

  • voidUpdate 3 hours ago

    Seeing as everyone is apparently seeing themselves having visited multiple times when it wasn't them, including me, I'm very happy with the privacy of this system =) It cannot effectively track me

  • elliotshep 3 hours ago

    It has 99.5% confidence this is my 10th visit. I've hit refresh once, but the rest aren't me. My other "visits" are from many countries, saying I've changed browser, IP, and location. They are using the same OS and browser though.

    • dontdoxxme 3 hours ago

      Same, it's all over the place. Whatever it is doing isn't a very strong fingerprint.

  • alexcroox 3 hours ago

    It shows I've visited twice already, from different countries, IPs and browsers. I don't think this works. This open source one does work between incognito and normal session: https://fingerprintjs.github.io/fingerprintjs/

    Saint-Jean-sur-Richelieu sounds lovely! as does firefox, I should check out one of them at least...

  • CrzyLngPwd 3 hours ago

    Chrome, Windows 11, apparently, it saw me loads of times, but my first visit was today.

    I'd love to use a reliable system like this to detect returning fake, banned, and bot users on my services.

  • alpenbazi 3 hours ago

    Haha, same here, first visit but system saw me severals times already. I have a quite unique setup..

    Works great! Thank you for fighting for users anonymity

    Opening the site from two different temporary tab containers in Firefox yields different IDs.

  • aspect0545 3 hours ago

    Works great, my device visited over 100 times already

    edit: not only that, under past visits I can now see the ip address of other visitors, together with their rough location and browser setup. You may want to remove the "gdpr compliant" from the website :)

    • JohnMakin 14 minutes ago

      Don’t worry, it was 0/2 in detecting my browser or OS, like not even close, and I don’t do anything to obfuscate that, so it’s probably accidentally compliant

    Happy to answer any technical questions or discuss implementation details.

    • Alifatisk 3 hours ago

      People in the comment section has noted the site to recognize multiple page visits from them even though this is their first time visiting the site, did you test your service yourself on different browsers / os / devices ?

      • difosfor 3 hours ago

        Perhaps he's posted this here to get some more test data

  • mcgoooo_andrew 3 hours ago

    thinks i have visited multiple times when i definitely haven't, did you test this on macs?

  • vardump 2 hours ago

    Definitely not working at all.

    It shows I've visited all around the world, lots of times.

    Nope. Just once, and from one location.
