0.400one client stack dominates — normal for an API or a CDN origin.

Spread is entropy over the fingerprints reaching this domain, not over the domains a fingerprint reaches. It can’t distinguish one scraper from many people — it measures the mix of software, not who runs it.

Client stacks reaching this name

Busiest 15 client stacks on this page. Share is the fraction of this name’s observations. Many distinct fingerprints on a low-traffic name is itself worth a look; a blank JA3 is a permuting client — open the fingerprint for its variants.

Apple Safari / WebKit
Apple SecureTransport cipher-suite signature — Safari (macOS/iOS), WKWebView, and native URLSession apps; the 3DES legacy tail (0xC008/0xC012/0x000A) is Apple's tell, no other modern stack carries it. Platform entry like Android's Conscrypt: Apple system TLS legitimately offers any ALPN (h2, http/1.1, dot, none), so the cipher list alone is the signature — not ALPN-gated

Python requests / urllib3
official CPython build (OpenSSL 3.0.x — Windows / macOS / uv); ja4_b is the build, ja4_c b26ce05bbdd6 is urllib3's own SSLContext (post_handshake_auth, no session ticket) — httpx on the same build differs by that one extension. First seen as Windows 10, Python 3.14.
