Have you ever been confused about the difference between an Agent and a Launcher? Don't worry! They work together in Multilogin, but their functions are completely different. Let's take a detailed look.

What is an Agent?

Agent is a small desktop application that you can download and install on your device. It runs quietly in the background, ensuring that the launcher operates properly. You can think of it as a backstage worker making sure the show goes smoothly.

What does an agent do?

Set up the correct folder structure in /username/mlx

/username/mlx

Download the launcher (if missing or outdated)
Start the launcher

What is a launcher?

The launcher is where all profile launches occur. It interacts with profiles, manages profiles, and connects to the backend. If the Agent is the assistant, then the launcher is the main character that completes the tasks.

What is the function of a launcher?

Find and download browser kernels when needed
Manage them by starting and stopping profiles
Save profile data and upload it to the cloud

How Everything Comes Together

The way the Agent and the launcher cooperate is as follows:

Connect the Agent
The Agent starts and updates the launcher
The launcher connects to the database and loads the profile data
The launcher starts the profiles so that you can begin working

Without the Agent, the launcher cannot start at all. Without the launcher, your profiles will not work. Now that you understand how they work, you will know exactly what is happening if something goes wrong.
