DatapacksJava
Disable Spawner Mob Spawns
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This datapack flips the new gamerule spawnerBlocksEnabled to false, so mob spawners stop spawning mobs. Natural spawning is untouched.
⚠️ Requires Java Edition snapshot 25w37a or newer (the snapshot that introduces spawnerBlocksEnabled). Works in single-player and servers.
What it does
- On world load, sets:
/gamerule spawnerBlocksEnabled false
Result: all mob spawners won’t spawn anything.
Does not change natural spawning, eggs, commands, or mob farms that don’t rely on spawners.
Install
Drop the ZIP into your world/server datapacks/ folder.
Run /reload (or restart the server).
Uninstall
Remove the datapack.
Re-enable spawners with:
/gamerule spawnerBlocksEnabled true
