ja4-fingerprint

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.

HTTP client that can impersonate web browsers

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.

TLS fingerprint emulation upstream proxy replay any ClientHello

HAProxy (community) Lua Plugin for JA4 TLS Client-Fingerprinting

A local MITM proxy that lets you control TLS fingerprints (JA3/JA4), HTTP/2 fingerprints, HTTP header order, and User-Agent — all from a single YAML config file.

mic (mina-is-cute) is a simple Golang proxy to evade JA4 fingerprinting

JavaScript TLS 1.3/1.2 implementation for Node.js, with full control over cryptographic keys and record layer.

JA4T TCP-Fingerprinting via eBPF

eBPF-native Network & Security plateform in a single binary

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.
