🎭 Patchright NodeJS

Patchright is a patched and undetected version of the Playwright Testing and Automation Framework.
It can be used as a drop-in replacement for Playwright.

Note

This repository serves the Patchright-NodeJS Package. To use Patchright with Python, check out the Python Package. Also check out the main Patchright Driver Repository

---

Install it from NPM

# Install Patchright from NPM
npm i patchright

# Install Chromium-Driver for Patchright
npx patchright install chromium

---

Usage

Just change the import and use it like playwright. Patchright is a drop-in-replacement for Playwright!

Warning

Patchright only patches CHROMIUM based browsers. Firefox and Webkit are not supported.

// patchright here!
const { chromium } = require('patchright');

(async () => {
  const browser = await chromium.launch();
  const page = await browser.newPage();
  await page.goto('http://example.com');
  // other actions...
  await browser.close();
})();

Best Practices

To be completely undetected, use the following configuration:

chromium.launchPersistentContext("...", {
    channel: "chrome",
    headless: false,
    viewport: null,
});

Patches

Runtime.enable Leak

This is the biggest Patch Patchright uses. To avoid detection by this leak, patchright avoids using Runtime.enable by executing Javascript in (isolated) ExecutionContexts.

Console.enable Leak

Patchright patches this leak by disabling the Console API all together. This means, console functionality will not work in Patchright. If you really need the console, you might be better off using Javascript loggers, although they also can be easily detected.

Command Flags Leaks

Patchright tweaks the Playwright Default Args to avoid detection by Command Flag Leaks. This (most importantly) affects:

• --disable-blink-features=AutomationControlled (added) to avoid navigator.webdriver detection.
• --enable-automation (removed) to avoid navigator.webdriver detection.
• --disable-popup-blocking (removed) to avoid popup crashing.
• --disable-component-update (removed) to avoid detection as a Stealth Driver.
• --disable-default-apps (removed) to enable default apps.
• --disable-extensions (removed) to enable extensions

General Leaks

Patchright patches some general leaks in the Playwright codebase. This mainly includes poor setups and obvious detection points.
