CAPTCHAs, or "Completely Automated Public Turing tests to tell Computers and Humans Apart," are challenges designed to differentiate between human users and automated bots on websites. With advancements in AI, CAPTCHAs have become more complex, incorporating text, image, sound, and puzzle-based challenges. Python solutions for bypassing CAPTCHAs focus on either mimicking human behavior to avoid triggering them or using CAPTCHA solving services that leverage AI and human workers. Popular tools include Bright Data's Web Unlocker, Playwright Extra with the Stealth Plugin, AntiCaptcha, Selenium with the Stealth Library, and 2Captcha, each offering varying capabilities and cost structures. These solutions range from premium APIs to open-source software, highlighting different strategies like user emulation and real-time human solving to effectively bypass CAPTCHAs.
