🚀 CfSolver

Cloudflare Turnstile detection and bypass utilities for Python web automation.

Small, focused helper utilities to locate Cloudflare Turnstile iframes (including inside closed/open shadow roots) and compute checkbox coordinates using either Patchright (Playwright-style) or Pydoll (CDP-native) backends.

---

PyPI	pip install cfsolver-python

✨ Highlights

• ✅ Detect Cloudflare Turnstile challenges automatically
• 🧭 Resolve iframe coordinates across open/closed shadow roots via CDP
• 🖱️ Click the checkbox using page.mouse.click (Patchright) or Pydoll executor
• 🔁 Retry logic and simple public API (expectAndBypass, is_challenge_present)

📦 Requirements

• Python 3.10+
• patchright>=1.61.2 (for Patchright backend)
• pydoll-python>=2.23.1 (for Pydoll backend)
• A Chromium browser binary available on your PATH (or point to its location)

⚙️ Installation

Install from PyPI:

pip install cfsolver-python

uv add cfsolver-python

---

Quick Start

Import the high-level API and call the convenience method:

from cfsolver import CfSolver

# Example (Patchright):
import asyncio
from patchright.async_api import async_playwright

async def demo_patchright():
    async with async_playwright() as p:
        browser = await p.chromium.launch(headless=False)
        page = await browser.new_page()
        await page.goto("https://nopecha.com/demo/turnstile")

        success = await CfSolver.expectAndBypass(page, backend="patchright", max_attempts=6)
        print("Bypass successful" if success else "Bypass failed")

asyncio.run(demo_patchright())

Pydoll Example

import asyncio
from pydoll.browser.chromium import Chrome
from pydoll.browser.options import ChromiumOptions
from cfsolver import CfSolver

async def demo_pydoll():
    options = ChromiumOptions()
    options.binary_location = "/usr/bin/chromium"

    async with Chrome(options=options) as browser:
        tab = await browser.start()
        await tab.go_to("https://nopecha.com/demo/turnstile")

        success = await CfSolver.expectAndBypass(page=tab, backend="pydoll")
        print("Bypass successful" if success else "Bypass failed")

asyncio.run(demo_pydoll())

API Overview

• CfSolver.expectAndBypass(page, backend="patchright", wait_seconds=5, max_attempts=10) — Detects and attempts to bypass a Turnstile challenge; returns True on success.
• CfSolver.is_challenge_present(page, backend="patchright") — Quick check whether a Turnstile challenge exists.
• CfSolver.get_coords_if_challenge(page, backend="patchright") — Returns coords dictionary or None.

Returned coordinate dictionary includes keys such as found, x, y, width, height, checkbox_x, checkbox_y, and src.

Examples

See the example scripts in src/cfsolver_python/examples/ for ready-to-run demos (Patchright and Pydoll).

Run an example:

python src/cfsolver_python/examples/patchright_turnstile_demo.py

Notes

• The solver uses CDP to pierce closed shadow roots when necessary. If you rely on Patchright, ensure the chosen browser/context supports CDP sessions.
• Adjust the Chromium binary location in examples if your system uses a different path.
