CaptchaNo runs on your own machine — the client starts it, so there is no endpoint to ping. 59 installs a week from npm. Last commit 19 Oct 2026.
Solve reCAPTCHA v2/v3/Enterprise, Turnstile, DataDome and image captchas from AI agents.
Nothing serious here today
Today is the operative word: we check CaptchaNo every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
