An educational client fingerprinting engine. This page shows exactly what this server and your browser can observe about the client making this request — right now, live, for you.
Each item below cites the specific observations it's based on and is hedged by how spoofable that evidence is. See cross-signal analysis.
Computed from raw observations (e.g. JA3/JA4 hashes, User-Agent guesses) — not sent by the client directly. See raw vs. normalized vs. derived.
Every individual observation this fingerprint is built from, grouped by category. Click a row with a highlighted background for an explanation of that signal.
