Each script shows a different tactic for avoiding Cloudflare 1020. No frameworks, no noise — just straight working examples.

Bypass Examples

Playwright Basic

Basic page load using vanilla Playwright (likely to trigger CAPTCHA or 1020).

Parameter	Description	Example
url	Target URL to load	'https://example.com'
timeout	Maximum wait time (ms)	60000
output_file	File to save page HTML	'page.html'

Playwright + Stealth

Hide webdriver flag, spoof plugins, patch headless indicators.

Parameter	Description	Example
target_url	URL to visit and scrape	'https://example.com'
headless	Run browser in headless mode	True
timeout	Maximum wait time (ms)	60000

Residential Proxy Rotation

Add a pool of rotating residential proxies for better IP reputation.

Parameter	Description	Example
target_url	URL to visit with rotating headers	'https://example.com'
user_agents	List of User-Agent strings to rotate	['Mozilla/5.0...', 'Chrome/91.0...']
extra_headers	Additional HTTP headers to include (optional)	{'Accept-Language': 'en-US,en;q=0.9'}
rotate_every	Number of requests before changing header	1 (rotate every request)

User-Agent + Header Spoofing

Randomized headers and modern user agents for each session.

Parameter	Description	Example
target_url	URL to visit with rotated headers	'https://example.com'
user_agents	List of User-Agent strings to rotate	["Mozilla/5.0...", "Safari/537.36"]
headers	Additional HTTP headers to include	{"Accept-Language": "en-US,en;q=0.9"}
proxy	Proxy server address (optional)	'http://user:[email protected]:8080'
timeout	Max time to wait for page load (seconds)	30

Human-like Behavior

Add mouse movement, scrolling, and timed delays.

Parameter	Description	Example
page	Playwright page object	page.goto('https://example.com')
sleep	Pause execution for realism	time.sleep(1.5) / await sleep(1500) (ms)
mouse.move(x, y)	Move mouse cursor to (x, y)	page.mouse.move(100, 100)
mouse.click(x, y)	Click at coordinates (x, y)	page.mouse.click(200, 300)
keyboard.press(key)	Simulate keyboard key press	page.keyboard.press('PageDown')
mouse.wheel(deltaX, deltaY)	Scroll page by delta	page.mouse.wheel(0, 400)

Full Flow Example

All combined: stealth, headers, proxies, behavior — in one script.

Parameter	Description	Example
proxy	Proxy server URL with auth	'http://user:[email protected]:8000'
user_agent	Browser user agent string	'Mozilla/5.0 (Windows NT 10.0; Win64; x64)...'
target_url	URL to navigate and scrape	'https://example.com'
headless	Whether to run browser in headless mode	True (Python) / true (Node.js)
delay_range	Range (seconds) for random delays between actions	0.5 to 2 seconds
