Persistence All Mobs
Persistence All Mobs is a Forge server mod that stops mobs from despawning naturally, and it covers most modded mobs as well as vanilla ones.
What it does
Normally Minecraft removes distant or idle mobs over time. This mod marks each mob it spawns as persistent, which uses the game's own persistence system so the mob stays in the world. Vanilla mobs are covered, and the mod supports most mobs added by other mods, so spawned creatures keep their place without manual tagging.
The mod only blocks the normal despawn routine. If another mod removes entities through its own custom code, that removal still happens, because this mod has no way to stop it. Behavior is set in a configuration file, and the mod is lightweight, adding little work to the server.
Persistence All Mobs is server-side only, so players join without installing it and only the server runs it. It is published for Forge 1.20.1 under the MIT License, and the code is not open source. Files for 1.20.1 date from 2026-07-18 to 2026-07-24.
Key features
Stops natural despawning
Mobs that would otherwise vanish when far from players or idle stay in the world.
Vanilla and modded mobs
The persistence applies to vanilla mobs and to most mobs added by other mods.
Built-in persistence
The mod sets the persistent flag that Minecraft already uses, instead of replacing the spawning code.
Configurable behavior
A configuration file controls how the mod behaves, and the server owner edits it before use.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Farms and mob collections
Keeping spawned mobs in place helps when a farm or display depends on specific creatures remaining in the area.
Long-running survival worlds
Creatures stay where they spawned instead of disappearing from a world that is explored slowly.
Who it’s for: Server owners who want mobs to stay in the world after spawning, and who run Forge 1.20.1 with modded mobs they want to keep.
How it compares
Keep Peaceful Enemies is server-side only, open source under the MIT License, and built for Quilt on 1.20 – 1.20.1, so it targets a different loader than this mod. No More Axolotl Despawns! is open source under no license claim of its own, requires the server while clients stay optional, and covers Fabric, Forge, NeoForge and Quilt on 1.20 – 1.21.8, only axolotls.
