Configure your Factorio server

Several options are available for creating and running your own Factorio server, allowing you to choose the method that best suits your needs and preferences.

Method 1: Using in-game options

To get started quickly, you can launch your server with just a few clicks directly from the game.

Launch Factorio.
Select Multiplayer > Host new game.
Choose your game type and click Next.
If your selected game mode requires it, configure your map settings and click Next again.
In the Multiplayer server settings window, make the following changes:
- In the Server name field, enter a custom name for your server.
- In the Server password field, type in a secure password that other players must enter to join.
- Under Visibility, ensure that only the LAN server visibility option is selected. Example
Click Play.

Method 2: Using a Factorio dedicated server

The Factorio executable supports command-line interaction, enabling you to run the server with minimal resource usage, as no graphics or audio are loaded on the server machine. Follow the steps below to deploy your server using Factorio in headless mode.

Note

Running a headless Factorio instance on Windows will prevent you from opening the game on the same computer.

Prepare the server settings file

Open File explorer and navigate to the Factorio installation directory.
Open the data folder.
Create a copy of the server-settings.example.json file and name it server-settings.json.
Open the new server-settings.json file using a text editor, such as Notepad.
Make the following changes to the JSON file:
- Next to the "name" and "description" fields, change the string values to identify and describe your server. Example
- Under "visibility", change the "public" field value to false.
- Next to the "game_password" field, type in a secure password that other players must enter to join. Example
Save your changes and close the text editor.

Start the server

Open PowerShell.
Using the cd command, navigate to the Factorio installation directory.
Example
```
cd "C:\Program Files\Steam\steamapps\common\Factorio"
```
Run the following command to create a new save file, where the server will store its progress.
```
.\bin\x64\factorio.exe --create .\saves\savefile.zip
```
Use the command below to initialize your server with the newly created save file and the previously configured settings file:
```
.\bin\x64\factorio.exe --start-server .\saves\savefile.zip --server-settings .\data\server-settings.json
```
If the server is started successfully, the last few lines in PowerShell should read similar to the following:

Note

(Optional) Automate server launch

Take the following steps to create your server launch script file:

Open a text editor, such as Notepad.

Add the following lines to the file, replacing the placeholder <\path\to\Factorio> with the path to the Factorio installation directory.

@echo off

title Start your Factorio server

echo Starting server... 
cd /d "<\path\to\Factorio>" 
start /wait "" .\bin\x64\factorio --start-server .\saves\savefile.zip --server-settings .\data\server-settings.json

pause

Example

Click File > Save As.
From the Save as type list, select All files, and use a file name with a .bat extension. For example, factorio-server.bat.
Choose a convenient location where the file should be saved, such as Desktop, and click Save.
