LAN Server Options adds an Advanced options screen to Minecraft's built-in LAN flow.

It lets the LAN host configure extra integrated-server settings before opening the world:

• Toggle online-mode.
• Toggle whitelist flags.
• Toggle PvP.
• Change the LAN MOTD/server message.
• Change the maximum player count from 1 to 100.
• Change the idle timeout from 0 to 1440 minutes.

Only the player hosting the LAN world needs the mod. Joining players can use vanilla Minecraft.

Requirements

• Minecraft Java 26.2
• Fabric Loader 0.19.3 or newer for 26.2
• Java 25

Fabric API is not required.

Security note

Disabling online-mode turns off account verification. Use it only on trusted networks because other players can impersonate usernames.
