用于快速请求HTTP或HTTPS，并支持修改ja3、ja4指纹

HTTP client that can impersonate web browsers

Fingerproxy is an HTTPS reverse proxy. It creates JA3, JA4, Akamai HTTP2 fingerprints, and forwards to backend via HTTP request headers.

Fingerprint-aware TLS reverse proxy. Use Finch to outsmart bad traffic—collect client fingerprints (JA3, JA4 +QUIC, JA4H, HTTP/2) and act on them: block, reroute, tarpit, or deceive in real time.

Multi-protocol passive fingerprinting library: TCP/HTTP (p0f-style) + TLS (JA4-style) analysis in Rust

httpmorph is a drop-in replacement for Python's requests library that uses a custom C implementation with BoringSSL instead of Python's standard HTTP stack.

HTTP client for Node.js with browser TLS fingerprint impersonation

A new approach to fighting cross-session tracking: multi-layer online fingerprint obfuscation. Spoofs browser/OS (headers & JS), hardware, TLS cipher-suite, canvas, peripherals and much more.
