Signal Library
Browse the 300+ browser signals Device Identification collects. Each signal is documented with its cross-session stability rating.
Canvas & Rendering
Very StableHow the device draws graphics reveals its GPU, drivers and text rendering stack — a stable trait that survives browser updates.
WebGL & GPU
Very StableThe 3D graphics pipeline exposes the physical graphics hardware and its driver generation, one of the strongest device traits available in a browser.
Audio Processing
StableThe audio stack processes sound in ways that differ by hardware and operating system, adding a dimension that graphics alone cannot provide.
Font Detection
StableInstalled typefaces and how the system renders them reflect the operating system, its language packs and software installed by the user.
Navigator & Browser
VariableWhat the browser reports about itself — and, more usefully, whether those claims agree with each other and with everything else we observe.
Screen & Display
StableDisplay geometry and colour capabilities describe the physical monitor and how the system is configured to drive it.
Network & Connection
VariableConnection characteristics reveal VPNs, proxies and datacentre traffic hiding behind an ordinary-looking IP address.
Security & Privacy
StablePrivacy protections, hardened browser modes and traces of tools built to falsify the other categories above.
We publish what each direction tells us about a device — not the individual checks behind it. The exact probe set and its weights stay internal: that list is precisely what someone building an evasion tool would need.
