CapSkip SDKs

Captcha solving SDKs for every stack

One local solver, four official clients. CapSkip runs on your machine and exposes a standard captcha-solver HTTP API, and each SDK wraps it with clean method names so you can solve image captchas, reCAPTCHA v2 and v3, Cloudflare Turnstile, GeeTest v3, ALTCHA, CaptchaFox, Capy Puzzle and Friendly Captcha from your own code.
