GitHub hosts numerous open-source projects aimed at solving CAPTCHAs using artificial intelligence (primarily computer vision and deep learning). These solvers target text-based, image-based, and audio CAPTCHAs. While valuable for security research and automation testing, they raise ethical and legal concerns regarding unauthorized bypassing of website protections.
Note: Many popular CAPTCHA solvers are taken down due to policy violations or DMCA requests from Google (reCAPTCHA) and other providers.
: Often used for character recognition once detection is complete. Some repositories like project_captcha focus on splitting CAPTCHAs into single characters and then classifying them using a CNN.
