用于快速请求HTTP或HTTPS，并支持修改ja3、ja4指纹

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.

TLS fingerprint emulation upstream proxy replay any ClientHello

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.

JA4 proxy tooling.

Engine-independent TLS fingerprint library for Go — JA3/JA4, uTLS browser impersonation, byte-exact HTTP/2, curl_cffi-style HTTP client. Zero CGO.

Asymmetric defense against adversarial AI agents. VeilGate evaluates each incoming request, redirects suspected agents into a per-IP-consistent honeypot environment, and quantifies the computational cost imposed on the attacker.

JA4+ Fingerprinting Library in Golang

Self-hosted JA4 bot challenge for stock nginx — or a gateway container in front of any HTTP server. Search-bot safe by design. PoW + behavioral CAPTCHA, RPM/DEB/APK + Docker.

Adversarial HTTP proxy for replicating real browser TLS and HTTP fingerprints

Go http.Client with a byte-exact browser TLS fingerprint (uTLS) — survive JA3/JA4 blocking without a headless browser.

Stop guessing why your scraper gets 403'd. wafprobe runs surgical probes that mutate one client fingerprint axis at a time and tells you exactly which signal the WAF is checking. Detects Cloudflare, Akamai, DataDome, PerimeterX, Imperva, AWS WAF, Kasada, Shape.
