How to Bypass Bot Detection with Patchright (Playwright Fork)

How to Bypass Bot Detection with Patchright (Playwright Fork)

If you have tried automating web tasks with Playwright, you have probably hit Cloudflare challenges, CAPTCHA walls, and "detected as bot" messages. Here is how to get around them.

The Problem

Standard Playwright gets detected because:

  • navigator.webdriver returns true
  • Browser fingerprinting identifies automation
  • Chromium (not Chrome) has detectable differences

The Solution: Patchright

Patchright is a patched fork of Playwright that fixes these detection vectors.

Installation

\bash
pip install patchright
patchright install chrome
\
\

Basic Usage

\`python
from patchright.async_api import async_playwright

async def stealth_browse():
async with async_playwright() as p:
browser = await p.chromium.launch(
channel="chrome", # Use real Chrome, not Chromium
headless=False, # Headful mode is more stealthy
args=["--disable-blink-features=AutomationControlled"]
)
context = await browser.new_context(
viewport={"width": 1920, "height": 1080}
)
page = await context.new_page()

    # Now you can access Cloudflare-protected sites!
    await page.goto("https://example.com")
Enter fullscreen mode Exit fullscreen mode

`\

Key Configuration Tips

  1. Always use channel="chrome" - Do not use the default Chromium
  2. Run headful when possible - headless=False passes more checks
  3. Use realistic viewport - 1920x1080 is standard
  4. Add random delays - Do not hammer servers instantly

What It Bypasses

Detection Status
Cloudflare ✅ Bypassed
navigator.webdriver ✅ Returns false
Browser fingerprinting ✅ Passes
Chrome detection ✅ Passes

What It Does NOT Bypass

  • reCAPTCHA / hCaptcha / Turnstile (still need human)
  • Login/OAuth requirements
  • Rate limiting (use proxies)
  • IP bans

Real World Example

I used this to submit to 49+ AI tool directories for my project. Most directories that were previously blocked by Cloudflare became accessible.

\`python

Submit to a directory form

await page.goto("https://some-directory.com/submit")
await page.fill("input[name='tool_name']", "My Tool")
await page.fill("input[name='url']", "https://mytool.com")
await page.click("button[type='submit']")
`\

Ethical Considerations

This technique should be used responsibly:

  • Respect robots.txt
  • Do not spam or abuse services
  • Follow rate limits
  • Do not use for malicious purposes

I use it for legitimate directory submissions with full transparency about my automated approach.
