TLS fingerprinting · uTLS

Your traffic doesn't imitate a browser. At the byte level, it is one.

Crusader routes live proxy traffic through real uTLS handshakes — so targets see a genuine Chrome (or Firefox) fingerprint across every layer their bot-defense actually inspects. Not a User-Agent swap. Not a header spoof. The real thing, verified by third-party fingerprinting tools.

3 / 3 fingerprint layers matched  ·  0-byte deviation on the Chrome HTTP/2 fingerprint  ·  Chrome & Firefox profiles  ·  Verified on tls.peet.ws

The report card

Every value below is pulled from tls.peet.ws — an independent third party — and is reproducible in a browser tab routed through Crusader.

The proof — don't take our word for it

Point any fingerprint checker through Crusader.

It reports Chrome — JA4 t13d1516h2…, the exact Chrome Akamai HTTP/2 hash 52d84b11…, headers in true browser order. Competitors claim stealth. You can demonstrate it, live, in the visitor's own browser.

Generic proxy engine

JA3 80f376a4c80ffcd3bf69acb8b8cd1781 — a fixed fingerprint no browser on earth has.

Crusader

A live Chrome handshake whose JA3 rotates every connection, exactly like Chrome's TLS-extension shuffle.

Three layers, not one

Most tools match the TLS layer and stop. Bot-defense inspects all three — and notices when the other two don't line up.

Layer 1 — TLS

JA3 / JA4 — the real ClientHello

A genuine Chrome ClientHello via uTLS: ciphers, extensions, key shares, GREASE, post-quantum (X25519MLKEM768), and ECH. Byte-exact.

Layer 2 — HTTP/2

Akamai fingerprint

Matching SETTINGS, WINDOW_UPDATE, and pseudo-header order — the fingerprint most tools ignore entirely.

Layer 3 — headers

HTTP header order

The browser's exact wire order, preserved end-to-end. Generic HTTP libraries alphabetize; anti-bot notices.

Why it wins

General-purpose intercepting proxies forward through their own runtime's TLS stack — a JVM or Rust fingerprint that instantly flags as "automation." Crusader is the interception proxy built to present a real browser to the target, and to prove it against public fingerprint oracles.

Fingerprints reproduce Chrome 133 / Firefox 135 profiles, validated against real-browser captures and verified live via tls.peet.ws. Optional attribution headers, when enabled, are added intentionally for authorized engagements.
