This article will guide you on how to start using automation in Multilogin in a few simple steps.

Step 1: download Multilogin and create an account

To start using Multilogin, download the app here. Once the app is installed, create an account by clicking “Create new account”.

create a new account in the app by clicking "Create new account"

To gain access to Multilogin API, you need to subscribe to our Scale or Custom plans. You can check our prices here. If you're unsure which option is best for you, contact [email protected], and we will happily help you choose the right plan.

  • If you're looking for a Custom plan, contact [email protected]
  • For the Scale plan, you can proceed with the purchase within the app through “View plans”.

Step 2: predefine the application listening port

Once your Scale or Custom subscription is active, you need to predefine the Multilogin listening port in the file, so that it is the same on each application launch. In our example, we will set the port to 35000.

  1. Open Multilogin
  2. Go to the “My account” tab on the left and click “Open logs directory”
  3. In the / directory that will open, go one folder up to get to the / folder
  4. Open the file with any text editor
  5. For our example, add the following string: multiloginapp.port=35000
The port number has to be in the range from 10000 to 49151.
  1. Save the file
 Predefine the application listening port

Alternatively, you can find the file in the directory:

This folder may be hidden depending on your OS settings.
  • Windows: C:\Users\%username%\
  • Linux: /home/%username%/
  • macOS: /Users/%username%/
To find this folder on Mac, open Finder and press Cmd + Shift + H to open a user folder, then press Cmd + Shift + . (period) to show hidden files. After that, go to the folder.

Step 3: familiarize yourself with Multilogin CLI and Local API

You can learn more about our CLI and Local API from our documentation.

All Local API endpoints are available in our Swagger documentation.

Step 4: test our code example

Here are code examples of how to open an existing Multilogin browser profile and perform simple Selenium and Puppeteer browser automation:
