Use a Python script to launch the Multilogin desktop app on Windows, macOS, or Linux before running other local automation.

➡️ Choose the script for your operating system → update the app path if needed → run the script from your IDE or terminal.

Use this when your automation workflow needs the Multilogin desktop app and its built-in launcher to be running first.

The agent needs a display in order to work. If your system doesn’t have one, use a virtual display. Example (for Linux):

xvfb-run mlx

Before you start

Make sure:

Multilogin desktop app is installed
Python is installed
You know how to run a Python script from your IDE or terminal
On Linux, a graphical display is available or a supported virtual display is configured

Windows

Run the script via IDE or Command Prompt. Don't know how? Read this article: Getting started with automation scripting.

import os
import subprocess

def connect_agent():
    username = os.getlogin()
    exe_path = f'C:\\Users\\AntonLa\\AppData\\Local\\Multilogin App\\MLXDesktopApp.exe'
    agent_connection = subprocess.run([exe_path])
    assert agent_connection.returncode == 0
    if agent_connection.returncode == 0:
        print("Agent connected")
    else:
        print(f"Failed to connect agent. Error {agent_connection.returncode}")

if __name__ == "__main__":
  connect_agent()

macOS

import subprocess

def connect_agent():
    agent_connection = subprocess.Popen(['open', '/Applications/Multilogin App.app/'])
    agent_connection.wait()  
    return_code = agent_connection.returncode
    if return_code == 0:
        print("Agent connected")
    else:
        print(f"Failed to connect agent. Error {return_code}")

connect_agent()
