[TUTORIAL] Bypassing Cloudflare Turnstile & Anti-Bot Systems (Playwright)

Standard Selenium or Requests libraries are instantly blocked by modern WAFs (Web Application Firewalls) like Cloudflare or Datadome in 2026. To successfully scrape data without getting IP banned, you must use undetected browsers. Here is the modern approach using Python and Playwright.

---

Why Selenium Fails:
Cloudflare checks the navigator.webdriver flag in your browser. Standard Selenium leaves this set to "true," instantly flagging you as a bot. We fix this by using playwright-stealth.

The Stealth Setup (Python):
First, install the required packages: pip install playwright playwright-stealth

from playwright.sync_api import sync_playwright
from playwright_stealth import stealth_sync

def scrape_secure_site():
    with sync_playwright() as p:
        # Launching with specific arguments to mask bot behavior
        browser = p.chromium.launch(headless=False, args=[
            '--disable-blink-features=AutomationControlled',
            '--disable-infobars'
        ])
        
        context = browser.new_context(
            user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36'
        )
        
        page = context.new_page()
        stealth_sync(page) # Applies the stealth patches
        
        page.goto("https://target-website.com")
        page.wait_for_timeout(5000) # Wait for Cloudflare JS challenge to resolve naturally
        
        print(page.title())
        browser.close()

if __name__ == "__main__":
    scrape_secure_site()

Security Note: Always rotate your residential proxies when running scraping loops to prevent subnet bans. Never hammer a server with 1000 requests per second.
