Primo Fingerprint Lab · identity & spoofing inspector Compare reports Quick probe ↗

Multi-session fingerprint capture

Start a run, then open the probe link in every tab / session you want to profile — different proxies, timezones, profiles. Each tab reports its full client fingerprint plus the exact TLS/JA3/JA4, HTTP/2 and header footprint the server sees on the wire. Stop to download one report comparing every session: what is spoofed, what leaks, and which fields are cross-linkable.

New run

Give it a label (e.g. the browser build/version you're testing) so reports are easy to tell apart later.
