client diversity
13 distinct client stacks reach this name.
concentration
0.635 traffic splits near-evenly across many unrelated stacks.
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.

Busiest 13 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 | — | multi-build | 1 | 1.0% | 2026-07-23 | 2026-07-23 |
