( 2captcha/2captcha-python ): A long-standing market leader with one of the most comprehensive Python SDKs available. The official 2captcha-python package supports over 30 CAPTCHA types, including all variations of reCAPTCHA, Cloudflare Turnstile, FunCaptcha, and hCaptcha. The repository also includes practical captcha-solver-selenium-python-examples showing how to integrate the solver with Selenium and Playwright for complete browser automation. The library offers both synchronous and asynchronous clients, along with detailed error handling and proxy support for bypassing rate limits.
: The gold standard for text recognition. You’ll often need to use OpenCV first to remove "noise" (lines or dots) from the image. captcha solver python github
CAPTCHA triggers are heavily tied to IP reputation. Avoid cheap or public data center proxies; instead, use elite residential proxies to mimic organic human traffic. Ethical and Legal Considerations
Interactive challenges requiring user engagement (e.g., Google reCAPTCHA v2/v3, hCaptcha, Cloudflare Turnstile).
Evaluation example (src/eval.py)
| Repository | Key Tech | Use Case | | :--- | :--- | :--- | | | OpenCV, Tesseract OCR | Solving simple text CAPTCHAs. It preprocesses images to enhance text and then extracts it. | | OCR-Captcha-Detection (MuhammadAfaan) | EasyOCR, Selenium | Solving a custom 3-digit grid CAPTCHA where digits must be read from tiles. | | captcha-ocr-solver-IMDA (laishaun) | EasyOCR, Python | A pipeline for recognizing 5-character CAPTCHAs, using contrast enhancement or background subtraction. |
The GitHub ecosystem offers two primary approaches: (free, requires setup) and API wrappers for human-in-the-loop services (paid, highly reliable). Local & Machine Learning Solvers (Open Source) 1. DDDDOCR (Decees Dumb Dumb OCR)

Modern CAPTCHAs track browser fingerprints. These repositories help your Python automation scripts bypass detection entirely:
