# Remove noise with median blur denoised = cv2.medianBlur(thresh, 3)

It supports every CAPTCHA type imaginable: reCAPTCHA v2/v3, hCaptcha, GeeTest, Cloudflare Turnstile, and even normal image CAPTCHAs. The code is clean, well-documented, and actively maintained.

Star 2captcha/2captcha-python and explore its examples. Then, for learning, clone a local solver like Captcha-Solver by xHak9x to understand the image preprocessing pipeline. Between these two, you will handle 99% of automation scenarios. Have you built a CAPTCHA solver using a different GitHub repo? Share your experience and success rate in the discussion below.

The secret to using pytesseract isn't the library itself; it's the preprocessing . GitHub repos like user-none/Captcha-Solver demonstrate how to remove background noise and lines before feeding the image to Tesseract. 3. captcha-solver by xHak9x (Hybrid) Stars: ~150 | Language: Python This lesser-known gem sits in the middle. It tries to solve simple CAPTCHAs locally using pytesseract , but falls back to a 2Captcha API if it fails. It’s an excellent template for building a resilient solver. 4. capsolver/capsolver-python (Modern API) Stars: ~80 (but rapidly growing) | Language: Python Capsolver is a newer competitor to 2Captcha that specializes in AI-based solving. Their Python SDK is excellent for reCAPTCHA and the increasingly common Cloudflare Turnstile . 5. python3-selenium-captcha-solver by honkyjoe (Specialized) Stars: ~200 | Language: Python This repository is unique because it demonstrates how to solve audio CAPTCHAs using Google's Speech Recognition API. It’s part of a Selenium automation script. While the accuracy is moderate, it shows a creative workaround for the audio fallback channel. How to Choose the Right Repository for Your Project Your decision depends entirely on your use case:

return text.strip() captcha_text = solve_simple_captcha('captcha.png') print(f"Solved: captcha_text")

from twocaptcha import TwoCaptcha solver = TwoCaptcha('YOUR_API_KEY') result = solver.normal('captcha.png') print(result['code']) Stars: ~300 | Language: Python Tesseract is a Python library that wraps Google's Tesseract-OCR engine. While not exclusively a "CAPTCHA solver," it is the most common tool for text-based CAPTCHAs.

The best approach is to hybridize: use a local solver from GitHub as a first-pass filter, then fall back to a paid API. This minimizes costs while maximizing success rates.
