# Convert to grayscale gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
However, the GitHub community is responding. New repositories are emerging that integrate with and undetected-chromedriver to mimic human mouse movements and keystroke timing, rather than solving the CAPTCHA directly. Conclusion Searching for "captcha solver python github" opens a door to dozens of solutions, but no silver bullet exists. For hobbyist projects with simple CAPTCHAs, pytesseract paired with OpenCV is sufficient. For anything involving Google, Cloudflare, or hCaptcha, the 2captcha-python or capsolver-python API clients are your only reliable options.
from twocaptcha import TwoCaptcha import requests from bs4 import BeautifulSoup solver = TwoCaptcha('YOUR_API_KEY') captcha solver python github
import cv2 import pytesseract from PIL import Image def solve_simple_captcha(image_path): # Load image with OpenCV img = cv2.imread(image_path)
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. # Convert to grayscale gray = cv2
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:
| Use Case | Recommended GitHub Repo | | :--- | :--- | | | 2captcha/2captcha-python or capsolver-python | | Internal legacy system (simple text CAPTCHA) | pytesseract + OpenCV preprocessing | | Learning image processing & ML | user-none/Captcha-Solver (local) | | Bypassing Cloudflare DDoS protection | capsolver-python (Turnstile support) | | Automated test environment (low security) | pytesseract | Step-by-Step: Building Your Own CAPTCHA Solver Pipeline in Python Let’s walk through a practical implementation using two popular GitHub-inspired approaches. Method 1: Local Solver for Simple Text CAPTCHAs This pipeline assumes the CAPTCHA has solid dark text on a noisy light background. This minimizes costs while maximizing success rates
For simple, old-school CAPTCHAs, pytesseract combined with PIL (Pillow) and OpenCV for preprocessing (greyscale, thresholding, erosion) can achieve 80-90% accuracy.
