Hard Mob Limiter
by nenuu91MOGS
Hard Mob Limiter sets a hard cap on natural mob spawning, with the cap applied per player and configurable for each mob type.
What it does
The cap is set in a config file and can be changed globally or per mob type. Mob spawns are limited so that a player who wants fewer than five of a given mob around them can keep that number, and a player who wants more can raise it. Only natural spawning is affected; mobs placed by other means are not counted by this setting.
A per-player radius setting decides how close other players must be before their mobs count toward the same limit. This helps avoid crowding when several players stand near each other. Spawn weights, which the mod does not replace, can still make some mobs appear more often than others.
Hard Mob Limiter runs on the server only, so players join without installing it. It is published for Forge, for 1.20.1 only, and is released under the MIT License, but it is not open source. Updating the mod will likely overwrite the config, so copy it somewhere safe first.
Key features
Per-player caps
The natural spawn limit is counted for each player rather than shared across the whole world.
Configurable per mob type
Each mob type can get its own cap, and the global value can be changed in the config file.
Player radius setting
A radius defines how close other players must be for their spawns to count toward the same limit.
Config backup advice
Updates can overwrite the config, so keeping a copy of the file before updating protects custom values.
Compatibility
Latest build for each game version and loader.

Use cases
Modpack servers
Pack makers can set spawn caps so a modded world keeps a steady mob count for everyone on the server.
Crowding control
Server owners can keep groups of players from drawing extra mobs when they stand near each other.
Who it’s for: Server owners and modpack makers who want to control how many natural mobs spawn for each player. It is server-side only, so clients do not need it.
How it compares
Mob Cap Limiter is a Forge mod for 1.12.2 under the MIT License, and it runs on both client and server, so every player must install it. Simple DamageCap is server-side only for 1.20.1 – 1.20.6 and is released under All rights reserved, so it is not open source. Spawning control is server-side only for 1.20.1 – 1.20.4 under the MIT License, but its versions differ from Hard Mob Limiter's single 1.20.1 build.
