client diversity
4 distinct client stacks reach this name.
concentration
0.561 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 4 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 |
|---|---|---|---|---|---|---|
| Google Chrome / Chromium Chromium cipher-suite signature — Chrome, Edge, Brave, Opera; any extension permutation or version | — | randomising | 31 | 69% | 2026-07-19 | 2026-07-23 |
| Google Chrome / Chromium Chromium cipher-suite signature — Chrome, Edge, Brave, Opera; any extension permutation or version | — | randomising | 12 | 27% | 2026-07-19 | 2026-07-23 |
| Android (Conscrypt) / Flutter (BoringSSL) mobile-BoringSSL cipher-suite signature — Android system TLS (Play Services, Firebase, OkHttp apps) and Flutter/Dart; any ALPN | — | randomising | 1 | 2.2% | 2026-07-19 | 2026-07-19 |
| 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 | 2.2% | 2026-07-21 | 2026-07-21 |
