	tl;dr: cfsolve is a Rust library and CLI that solves Cloudflare Turnstile widgets and challenge pages without a headless browser, returning either a Turnstile token or a cf_clearance cookie. It works by impersonating a specific browser via profile files containing recorded responses to Cloudflare's browser checks, with Safari on iOS included and support for Chrome(ium). Building requires a pinned Rust toolchain plus CMake, a C/C++ compiler, libclang, and Git for patching BoringSSL.
	HN Discussion: ↑Author providing context about regional variations and ongoing maintenance challenges ~Such solvers are inherently unreliable due to constant cat-and-mouse with Cloudflare ~Individual bypasses work but detection at scale is nearly impossible to defeat ↓Publishing bypasses publicly is counterproductive and accelerates CF's countermeasures against legitimate users ~Technical critique noting missing TLS cipher ordering as a likely detection vector
