Telemetry Inspector

See what your browser quietly reveals.

This page runs three real fingerprinting probes against your own browser - a canvas raster hash, a silent audio-context signature, and your unmasked WebGL GPU strings - then folds them into one device identity. Every byte is computed on this machine. Nothing leaves it.

Composite device identity

SHA-256 over all probe digests plus environment signals. Stable across reloads on this browser; different on another device or profile.

Canvas raster hash

Sub-pixel 2D rendering, SHA-256 of raw pixels

Audio context signature

Silent offline DSP graph, summed waveform

WebGL renderer (unmasked)

Direct GPU vendor & renderer strings

Environment signals

Platform, hardware & locale hints

Zero network telemetry

Every measurement on this page is computed in your browser using the same APIs that trackers use - then shown only to you. There is no request that carries a fingerprint off this device: no analytics, no logging endpoint, no beacon. Open your network tab and watch. The point is to make the invisible visible, not to collect it.
