Python binding for curl-impersonate fork via cffi. A http client that can impersonate browser tls/ja3/http2 fingerprints.

JA4+ is a suite of network fingerprinting standards

Go HTTP client with browser-identical TLS/HTTP2 fingerprinting. Bypass bot detection by perfectly mimicking Chrome, Firefox, and Safari at the cryptographic level (JA3/JA4, Akamai fingerprint, header order). Supports HTTP/1.1, HTTP/2, HTTP/3, sessions, cookies, and proxies.

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

Active NDR solution with eBPF-powered active fingerprint blocking, firewall and proxy. Protect your system -- east-west and north-south.

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.

JA4T TCP-Fingerprinting via eBPF

The most advanced asynchronous HTTP client for PHP. Bypass TLS protections with ease using AstraHTTP.

High-fidelity TLS stealth engine. Built in Go, it utilizes uTLS to mimic modern browser fingerprints and performs ALPN stripping to bypass JA3/JA4 detection, also forcing HTTP/1.1 downgrades. Built for lead generation, WAF evasion testing, etc.
