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:pass@proxy.com: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:pass@proxy.example: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
