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
An fast asynchronous Rust HTTP/WebSocket Client with TLS/JA3/JA4/HTTP2 fingerprint impersonate
🚀obtain the client's ja3 fingerprint, http2 fingerprint, and ja4 fingerprint
