Prove it

Don't trust our accuracy. Break it.

Every vendor claims high accuracy. Here you test ours on the one browser you control — yours. Identify yourself, then clear cookies, go incognito, switch tabs. We'll still know it's you.

Prove it — on your own browser
Run it, then try to fool it. Clear your cookies, open an incognito window, switch tabs — come back and run it again.
The hard test

Now try to actually evade it

Cookies are easy. Real fraud tooling spoofs the canvas, fakes the GPU and rotates everything. So we run those exact attacks on your browser — live.

Adversarial evasion battery
We run 12 real anti-detect-browser attacks against your own browser — spoof canvas, GPU, audio, timezone, UA, hardware, screen, wipe storage, then all at once — and check if we still know it’s you. Nothing is faked; it runs live.

Why this matters

A visitor ID is only useful if it's stable — the same device has to resolve to the same ID even when the user actively tries to look like someone new. Cookies fail this instantly. A real device fingerprint doesn't, because it's derived from the hardware, not stored on it.

Run the test above a few times across incognito and cleared storage. The times-seen counter climbs and the visitor ID stays identical — that's the whole product working, live, on your data, with nothing to fake.
