Mob Limiter
by mss1r
With Mob Limiter, a server owner caps how many mobs can exist in each chunk and across the whole world, which keeps mob farms from overloading a server.
What it does
Mob Limiter sets per-chunk and world-wide caps on mob spawning, so overcrowded farms and excessive mob spawns can be kept in check. Limits can target specific mob categories or namespaces, and modded mobs registered with Forge are supported. When a chunk or the world goes over its limit, excess mobs are removed through a silent despawn that still kills them with loot and experience. Despawn behavior can follow vanilla rules or custom despawn ranges, and persistent mobs can be handled separately.
The mod is a Forge server mod for Minecraft 1.20.1, released under the MIT License and not open source. Only the server needs it, so players join without installing anything. Limits have a priority system that lets specific mobs, categories or namespaces override the defaults. Asynchronous processing is meant to keep server performance steady. Config can be reloaded with a command, without restarting the server, and active settings can be displayed in game.
Key features
Per-chunk limits
Each chunk can be given its own cap on mob counts, which prevents clustering in farm areas.
Global world caps
A total limit on mob populations can be set for the whole world, separate from chunk caps.
Targeted restrictions
Restrictions can apply to particular mob categories or namespaces, including modded mobs.
Excess mob removal
Surplus mobs are removed by a silent despawn that kills them, so they still drop loot and experience.
Despawn control
Vanilla despawn rules can be kept, or custom despawn ranges and persistent mob handling can be set.
Live config reload
The moblimiter reload command refreshes the configuration, and moblimiter info shows the active settings.
