captcha

reCAPTCHA v3 never shows a puzzle. It scores every request from 0.0 to 1.0 and the site acts on a threshold you cannot see. Bypassing it means raising the score, not solving anything.

FunCaptcha is Arkose's interactive puzzle: rotate the object, match the image, and hand back a single-use fc-token the server verifies. This guide covers how the puzzle and token actually work, how solving fits, and why a clean residential setup keeps it rare.

GeeTest v4 scores your behavior, device, and IP, then picks a slide, icon, or gobang challenge by risk. Finding the slider gap is trivial; passing the trajectory and environment checks is the real work.

Arkose scores you first with 225+ risk signals, then serves an interactive FunCaptcha puzzle engineered to be expensive to solve at scale. No proxy solves that puzzle. A clean setup keeps it rare, and the token cannot be farmed.

Turnstile scores your browser environment with non-interactive JavaScript challenges and hands out a single-use token. No proxy mints that token. A clean residential IP and a real browser earn the invisible pass, and the token itself cannot be farmed.

hCaptcha scores you before it ever shows a puzzle, using device fingerprinting, behavior, and IP reputation. Residential proxies and a real browser reduce the challenges, and there is a fix for the ones that get through.

reCAPTCHA interrupts your scraping when your IP reputation or behavior looks automated. Knowing what triggers the challenge is how you see it far less often.
