GeeTest is a advanced CAPTCHA system that combines image recognition, slider puzzles, and behavioral analysis to distinguish humans from bots. Unlike traditional CAPTCHAs, GeeTest requires users to complete a puzzle—such as dragging a missing piece into a shape or clicking images in a specific order—while also tracking mouse movements and timing.

A is a third-party solution designed to automatically solve these challenges. These services are typically used by developers, automation tools, or businesses that need to bypass GeeTest for legitimate purposes (e.g., web scraping, automated testing, or accessibility support).
