NoSpawn

NoSpawn is a Fabric mod that disables spawning for selected mob types using in-game commands. It is useful for server management, modpack balancing, custom maps, and any setup that needs precise control over mob spawning.

Features

• Disable any single mob type or multiple mob types, not only the example mobs.
• Supports vanilla mobs and registered modded mob types.
• Supports both /ns and /nospawn.
• Works in singleplayer, LAN worlds, and dedicated servers.
• Saves disabled mob types to config/nospawn.json, so changes persist after restarts.
• Automatically switches between Chinese and English messages based on the player's game language.
• Supports LuckPerms permission groups with OP fallback.

Commands

<type> is a mob ID, such as minecraft:creeper, minecraft:vex, or minecraft:phantom. These are examples only; you can use any valid mob ID. After typing /ns add or /nospawn add , Minecraft will show available mob suggestions.

/ns
/nospawn
/ns add <type>
/ns remove <type>
/nospawn add <type>
/nospawn remove <type>

Examples:

/ns add minecraft:creeper
/ns add minecraft:vex
/nospawn add minecraft:phantom
/ns remove minecraft:vex

Permissions

Either OP permission or a matching LuckPerms node is enough. nospawn.admin allows every NoSpawn command.

nospawn.admin
nospawn.use
nospawn.add
nospawn.remove

LuckPerms examples:

/lp group admin permission set nospawn.admin true
/lp group helper permission set nospawn.use true
/lp group helper permission set nospawn.add true
/lp group helper permission set nospawn.remove true
