CAPTCHAs, or "Completely Automated Public Turing tests to tell Computers and Humans Apart," are designed to differentiate between human users and bots, typically presenting challenges that are simple for humans but tough for machines. Popular CAPTCHA variations include image, text, audio, and puzzle challenges, often integrated into broader anti-bot systems like Web Application Firewalls (WAFs). To bypass CAPTCHAs, tools like Playwright, a browser automation library, can be employed to mimic human behavior, often enhanced by plugins such as Playwright Extra and Playwright Stealth, which help avoid bot detection by modifying browser properties. Despite these measures, more advanced anti-bot systems might still detect scripts, requiring solutions like Bright Data's CAPTCHA Solver or Web Unlocker, which offer more robust responses by rotating IPs, managing browser fingerprints, and automatically solving CAPTCHAs.
