The developer of cfsolve says the Rust library and command line tool can solve Cloudflare Turnstile widgets and challenge pages without running a headless browser. Its documentation describes returning verification tokens or clearance cookies that allow requests through challenge pages.

The tool impersonates a browser using a profile and recorded responses to browser checks. It includes a Safari-on-iPhone profile and supports Safari and Chrome profile types. The claimed capability depends on matching browser details: Cloudflare will reject a clearance cookie sent from a different IP address or user agent. New challenge builds can also produce unsupported errors.
