Building or using a CAPTCHA solver in Python involves two main paths: creating a custom OCR (Optical Character Recognition) model for simple text images or integrating with third-party API services for complex challenges like reCAPTCHA. 1. Custom OCR Solutions (For Simple Text CAPTCHAs)

Handle Base64: Many sites do not serve the CAPTCHA as a raw image file but as a Base64 string directly in the HTML. You will need the base64 python library to decode it before passing it to your OCR or API solver. Installation: To install captcha-solver , run the following

For simple text-based CAPTCHAs, you can use Python libraries that rely on OCR (Optical Character Recognition) and Neural Networks. This approach is free but works best on older or less complex CAPTCHA types.
