About this project

Why this exists

Most people are told that “websites can track you” without ever seeing what that means in practice. This project makes it concrete: open the homepage and within a second you can read your own fingerprint hash, GPU string, canvas and audio signatures, font list, network attribution and behavioural metrics — the same values a commercial anti-fraud vendor would collect.

What you can do here

• Run the live analyzer — 30+ modules covering browser, device, network, behaviour and automation signals.
• Browser fingerprint test — how a stable device ID is built from canvas, WebGL, audio and fonts.
• WebRTC & VPN leak test — why a VPN can still expose your real address.
• Bot & automation detection — the tells that separate a human session from a headless one.

How the scoring works

Every score on this site is a transparent, weighted sum. Each signal has a documented point value, a plain-English label and a hint explaining what triggered it. Nothing is hidden behind a black box: if a score is 62, you can see the exact list of signals that added up to 62, and administrators can retune the weights on the settings page. That transparency is the teaching device — real vendors deliberately keep their weights secret.

Editorial standards

• Guides describe publicly documented browser behaviour and are revised when APIs change.
• We do not publish techniques whose only realistic use is committing fraud.
• Results are labelled heuristic wherever they are estimates rather than facts.
• Advertising is clearly separated from editorial content and never influences it.

Privacy stance

The analyzer is read-only by design. Fingerprint values are computed in your browser and are not uploaded; only the IP lookup and the optional signup demos touch our server. Full detail is in the Privacy Policy.
