Packaging notes:

The trade-off for portability is usually . Simple OCR fails on:

The "portable" GitHub projects you’ll find typically combine OCR for simple CAPTCHAs or provide wrappers for APIs.

No article on CAPTCHA solvers is complete without a strong disclaimer.

Before exploring the code, it's crucial to define portability. In this context, a highly portable CAPTCHA solver is one that emphasizes:

Always review the target website's Terms of Service [5.5].

Install the core libraries directly into your local environment: pip install ddddocr opencv-python pillow pyinstaller Use code with caution. Developing the Python CAPTCHA Solver

pyinstaller --onefile --add-data "lib/ddddocr;ddddocr" solver.py Use code with caution.

Let’s create a for simple alphanumeric CAPTCHAs using Python, OpenCV, and Tesseract. This entire script fits in <50 lines and runs on any OS with Python.
