SpawnConfig
by Code0211
SpawnConfig is a Forge server utility that caps how many mobs and other living beings can exist in each chunk, and it applies that cap to every spawn source.
What it does
Each mob type can have its own true or false toggle and a personal per-chunk limit, while a global per-chunk cap sets a hard ceiling on the total number of living beings in a single chunk. The mod intercepts the entity join world event, so the limits also block summon commands, command blocks and spawners once a limit is reached. Entities pushed into an overpopulated chunk are removed by the cleanup routine.
Server owners running heavy modpacks, such as packs that include TerraFirmaCraft or MCA Reborn, can use this tool to keep overpopulated mobs from dragging down performance, and it also works on plain vanilla Minecraft alongside Critters and Companions. Settings live in JSON files that appear in the config location after the first launch. Operators can change the global chunk limit or a single mob limit in game with spawnconfig chunklimit set and spawnconfig moblimit set, and spawnconfig moblimit reset restores the default for a mob.
The mod is published for Forge on 1.18.2 only, with its first file, 1.0.0 for 1.18.2, dated 2026-01-30. It is server-side only, so players join without installing it. The code is under All rights reserved and is not open source.

Use cases
Modpacks with heavy mob load
Packs such as those with TerraFirmaCraft or MCA Reborn can set tight limits on the mobs that strain the server.
Command-driven worlds
Servers where players or scripts summon mobs can rely on the same caps, since summons are blocked as well.
Who it’s for: The mod suits server owners and operators of Forge 1.18.2 servers who want to control total population and mob counts, and who prefer a small set of JSON settings over a complex configuration.
