To change the maximum number of players of your Factorio server, head to the Settings tab on the Control Panel. If you do not want to limit players change the value to 0.

Note that while Factorio has a theoretical maximum of 65,535 players, reaching this number is extremely difficult. It is best to limit your servers to 255 slots or lower, and only use high slot counts on our more powerful plans.

  1. Go to your server on our Control Panel.
  2. Click Settings in the server navigation bar.
  3. Click Game on the left menu.
  4. Change the max players to the desired value.
Note: You must restart your server for the changes to take effect.
