client diversity
14 distinct client stacks reach this name.
concentration
0.565 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 14 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.
| client | JA3 | stability | count | share | first seen | last seen |
|---|---|---|---|---|---|---|
| Node.js https / axios / got (no ALPN) Node 18–20 — bundled OpenSSL 3 (same on Debian & Alpine) | — | multi-build | 54 | 63% | 2026-07-19 | 2026-07-23 |

| 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.

| 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 | 1.2% | 2026-07-23 | 2026-07-23 |
