Supercharge your servers' performance, without breaking grinders.

Many people (rightly so) advise against using mob stackers because of their impact on gameplay for a minuscule performance gain. StackMob offers the flexibility your server needs so you can target the worst lag offenders, without ruining the fun for everyone else.

Features:

  • Supports Paper 1.21.11+
  • Ability to blacklist certain spawn reasons, entity types or worlds to prevent stacking
  • Ability to only stack mobs if they have moved.
  • Hidable nametag - nametag only appears when the player is in close proximity or when blocks aren't in the way
  • Supports entity renaming - the nametag does not get overridden to display the stack size, rather packets are used to have a second tag.
  • Support for all entity traits (sheep colours, age, love mode etc)
  • Configurable entity event behaviours. (i.e. when a sheep is sheared you can decide whether each sheep is sheared individually or they all get sheared at once.)
  • Ability to disable stacks from targeting players.
  • Multiple death methods - different ways to decrease entity stack size. Chose from single die, all entities die, random amount die or an amount dependent on damage caused get removed.
  • Multiplication of drops, experience points and player stats on stack death. -'Wait to stack' feature. Allows a brief period of time after initial spawn before stacking is enabled. This means that mob grinders do not get broken as entities don't merge in mid-air.
  • Support for plugins such as MythicMobs, Citizens, MyPet, Jobs, ClearLagg, McMMO and WorldGuard (a custom 'entity-stacking' flag to be used in regions)
  • Flexible Configuration! Most configuration options can be customised for specific entity types.

Sorry its taken a while, but this is the release for 1.21.3/1.21.4
  • "Armor stand" name tags are now displayed using display entities. This means that ProtocolLib is no longer required. But as a result:
  • Support has been dropped for Spigot. It became impossible to support components as display names on Spigot platforms. In theory a leagcy version could be made for spigot if people deeply desire that.
  • The plugin only supports 1.20.4+ also as a result of the above.
  • Improve animal splitting behavour when dying entities
  • Fix bees stacking when emerging from hives
  • Remove debug message

  • Support for 1.20.6 (yes, I am aware 1.21 did just get released)

[5.8.9] StackMob 5.8.9 by ploppyperson on Oct 13, 2026

Supports 1.20.4. We now require ProtocolLib.
Also there is now a timeout for check-location to hopefully prevent situations where entities can stack but can't because they are stuck.

(yes it took a while for this update, I am very good at procrastination)
