What does your browser hand over the moment you open a page?
Run a live audit and watch your own hardware, network, and privacy signals get read out in real time. Nothing you see here is simulated.
What this does
TraceLine runs the same fingerprinting techniques ad networks and data brokers use, entirely in your browser tab, and shows you the result instead of hiding it.
What it needs from you
One click. The audit reads your canvas, audio, GPU, and network signals through standard browser APIs. No login, no download, no camera or mic access.
Everything runs locally. There's no server behind this page, and closing the tab clears everything it found.
