Patchright SOP

Appearance

Install ​

Patchright ships as separate packages per language. Install the one that matches your runtime.

Python ​

bash
pip install patchright
patchright install chromium

The first command installs the Python package. The second downloads the patched Chromium browser binary. Run both commands; skipping the second will cause a "browser not found" error at runtime.

To install Google Chrome instead of Chromium (recommended for maximum stealth):

bash
patchright install chrome

Node.js ​

bash
npm i patchright
npx patchright install chromium

Or with pnpm:

bash
pnpm add patchright
pnpx patchright install chromium

The install chromium step downloads the patched browser binary and must be run after the package install.

.NET ​

bash
dotnet add package Patchright

See the patchright-dotnet repository for browser binary installation steps specific to the .NET runtime.

Notes ​

  • Only Chromium-based browsers are supported. Do not attempt to install Firefox or WebKit.
  • The install chromium step is separate from the package install and is required before first use.
  • For production stealth work, prefer channel="chrome" (Python) or channel: "chrome" (Node.js) to launch the system-installed Google Chrome rather than the downloaded Chromium build.
