How does device comparison work?
Generate a unique QR code on one device, then scan it from another device. Both devices' fingerprints are compared side-by-side showing differences in browser, screen, hardware, and other characteristics.
Why compare devices?
Comparing helps you understand how different devices appear to websites. You can see if your phone and laptop have unique fingerprints, or test how privacy tools change your fingerprint across devices.
Is my comparison data stored?
Comparison data is stored temporarily and locally using URL parameters. We don't store your device information on our servers. Data is only shared between the devices you scan.
Can I compare more than two devices?
Currently, comparisons work between two devices at a time. For multiple devices, run separate comparisons or note down fingerprints manually to compare later.
