sardanioss/httpcloak
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. observed · 2026-09-03

httpcloak is a Go HTTP client library that reproduces browser-identical TLS, HTTP/2, and HTTP/3 fingerprints (JA3/JA4, Akamai, header ordering) to bypass bot detection. It ships bindings for Python, Node.js, and .NET via a shared cgo library, with sessions, cookies, and proxy support including MASQUE.
Use cases
- scrape sites protected by Cloudflare bot detection
- make requests indistinguishable from Chrome at the TLS level
- bypass JA3/JA4 fingerprint blocking
- send HTTP/3 requests with browser-matching QUIC parameters
- rotate browser presets like chrome-latest or firefox in a scraper
- use encrypted SNI (ECH) to avoid SNI-based blocking
- persist sessions with cookies and TLS tickets across processes
When to choose
- you need HTTP/3 or ECH support that curl_cffi lacks
- you're blocked by TLS or HTTP/2 fingerprinting on a target site
- you want one API across Go, Python, Node.js, and .NET
- you need MASQUE proxying or domain fronting
When to avoid
- you just need a normal HTTP client with no anti-bot concerns
- your use case violates a site's terms of service or local law
- you need a pure-Python or pure-JS implementation without native binaries
- you require long-term stability guarantees from a mature ecosystem library
