Install

Step 1 - Install the Python packages

pip install langchain-community playwright

langchain-community ships the PlayWrightBrowserToolkit class and all seven browser tools. playwright is the Microsoft Playwright Python binding (version >=1.28.0,<2.0.0 is required by langchain-community).

Step 2 - Install Playwright browsers

After the pip install, download the browser binaries. Chromium is sufficient for most use cases:

playwright install chromium

To install all supported browsers (Chromium, Firefox, WebKit):

playwright install

Optional - install system dependencies (Linux / CI)

On headless Linux servers the browsers need OS-level libraries. Install them with:

playwright install-deps

Full one-liner for CI

pip install langchain-community playwright && playwright install chromium
