cloudflare-bypass

(★ 39)

This repository provides minimal working examples for bypassing Cloudflare 1020 errors using Playwright in both Python and Node.js. The focus is on showing basic setups to load pages that are often protected by anti-bot measures, with step-by-step improvements like stealth plugins, proxy rotation, and human-like behaviors.

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`                               |
