BROWSER + CONNECTION
Your browser fingerprint.
The pixels it draws. The APIs it exposes. The handshake it sends.
Raw measurements, together, with nothing turned into a bot score.
RENDERING SIGNATURE
Measuring…A hash of these rendering tests, not proof of a unique person.
TLS CLIENT FINGERPRINT · JA4
Waiting for the handshake…The connection is measured before HTTP processing.
Tests run automatically and save a shareable snapshot, including connection information. Anyone with its link can view it. Location and keyboard-layout access require your action.
