Playwright Automation Example

Author Yelena V (Updated on March 5, 2026)

Updated on March 5, 2026

Playwright is an open-source automation library designed to test web applications and automatically interact with web browsers. It provides comprehensive control over browser actions, including navigation, form filling, element clicking, and extracting data from web pages.

In this article, we will provide a simple script to launch a browser profile and connect it to Playwright.

You can use Playwright to automatically mimic browser profiles for your web crawlers. Please note that Stealthfox in Multilogin is not yet available in Playwright.

Before You Begin

JavaScript

  • Download Node.js from the official website and install it
  • Make sure Node.js and npm (Node Package Manager) are installed correctly:
node -v 
npm -v

node -v 
npm -v
  • Create a project directory, then run this command to initialize a new Node.js project and create a package.json file:
package.json

npm init -y

npm init -y
  • Install Playwright as a dependency for your project:

npm install playwright

npm install playwright
  • Install the Axios and MD5 libraries:
npm install axios 
npm install md5

npm install axios 
npm install md5
  • Insert your values into the following variables in the script: email: your Multilogin account email password: your Multilogin account password (no MD5 encryption needed) folder_id, profile_id: find these values using the guides on DevTools or Postman
  • email: your Multilogin account email
email
  • password: your Multilogin account password (no MD5 encryption needed)
password
  • folder_id, profile_id: find these values using the guides on DevTools or Postman
folder_id

profile_id

Python

  • Install the following Python library: playwright
  • Requirements
  • playwright
  • Install the necessary browser binaries:
playwright install

playwright install

  • Insert your values into the following variables in the script:

USERNAME: Your Multilogin account email

PASSWORD: Your Multilogin account password (no MD5 encryption needed)

FOLDER_ID, PROFILE_ID: Find these values using the guides in DevTools or Postman

  • USERNAME: Your Multilogin account email
USERNAME
  • PASSWORD: Your Multilogin account password (no MD5 encryption needed)
PASSWORD
  • FOLDER_ID, PROFILE_ID: Find these values using the guides in DevTools or Postman
FOLDER_ID

PROFILE_ID

Run Script

JavaScript

  • Launch the application, as it can open the profile page
  • Ensure Playwright is compatible with the current Mimic core version – check the Playwright and Mimic release notes
  • Run the .js file using automation code
.js
