FingerprintJS Studio

Generate a persistent browser fingerprint and visitor ID from canvas, audio and hardware signals.

FingerprintJS Studio — identify any browser with a persistent hashed visitor ID from canvas, audio and hardware signals.

How to use FingerprintJS Studio

  1. Click Generate my visitor ID to collect the entropy signals from your browser.
  2. Read your 128-bit visitor ID and copy it for use in your own tests.
  3. Open the entropy sources table to inspect every signal that went into the hash.
  4. Come back later: the saved ID shows whether your fingerprint stayed stable.
  5. Clear the saved ID any time to start the comparison fresh.
