Patchright vs Playwright: When to Use the Stealth Browser Fork

Playwright is great for testing. But what if you need to automate something that has bot detection? Enter Patchright.

What is Patchright?

Patchright is a fork of Playwright that patches common detection vectors:

• Sets navigator.webdriver\ to false


• Removes automation flags from Chrome


• Uses real Chrome instead of Chromium

Install

\bash

pip install patchright

patchright install chrome

\\

Basic Usage

\`python

from patchright.sync_api import sync_playwright

with sync_playwright() as p:

browser = p.chromium.launch(

channel="chrome", # Use real Chrome

headless=False, # Headful is more stealthy

args=['--disable-blink-features=AutomationControlled']

)

page = browser.new_page()

page.goto("https://example.com")

# Do your automation

browser.close()

`\

What It Bypasses

What It Doesn't Bypass

• reCAPTCHA


• hCaptcha


• Turnstile (usually)


• IP-based rate limiting


• Behavioral analysis

Async Version

\`python

from patchright.async_api import async_playwright

import asyncio

async def main():

async with async_playwright() as p:

browser = await p.chromium.launch(

channel="chrome",

headless=False

)

page = await browser.new_page()

await page.goto("https://example.com")

await browser.close()

asyncio.run(main())

`\

Stealth Tips

1. 
   Use headful mode - Headless is more detectable


2. 
   Add random delays - await asyncio.sleep(random.uniform(1, 3))\
   


3. 
   Type like a human - Use type(text, delay=50)\ not fill(text)\
   


4. 
   Move the mouse - page.mouse.move(x, y)\
   


5. 
   Don't override user agent - The default is better

When to Use Playwright vs Patchright

Legal Note

Only use for:

• Sites you own


• Sites that permit automation


• Research/educational purposes

Don't use for spam, scraping terms-violating sites, or bypassing rate limits maliciously.

Real Example: Directory Submission

I used this to submit my AI tools to 50+ directories:

\`python

async def submit_to_directory(url, tool_info):

async with async_playwright() as p:

browser = await p.chromium.launch(channel="chrome", headless=False)

context = await browser.new_context(viewport={'width': 1920, 'height': 1080})

page = await context.new_page()

    await page.goto(url)

    await asyncio.sleep(random.uniform(2, 4))



    # Fill form with human-like delays

    await page.fill('#name', tool_info['name'])

    await asyncio.sleep(random.uniform(0.5, 1.5))

    await page.fill('#url', tool_info['url'])

    # ...



    await browser.close()
