Mob Farm Schematics

A mob farm creates a dark area where hostile mobs can spawn, then moves them to one place to be killed. Since Minecraft 1.18, most hostile mobs in the Overworld only spawn where the block light level is 0, so spawning platforms are enclosed and kept dark. Water streams, trapdoors or drops carry the mobs off the platforms, and they are finished by fall damage or at a kill spot where you hit them yourself to collect experience.

Hostile mobs cannot spawn within 24 blocks of the player, can randomly despawn beyond 32 blocks and despawn instantly beyond 128 blocks, so the AFK spot matters as much as the farm. Building high in the sky or over an ocean, or lighting up nearby caves, sends more spawns to the farm's platforms. Some designs target a single mob: creeper farms for gunpowder, skeleton farms for bones and arrows, or spawner farms built around a dungeon spawner.

Look for the creator's notes on the AFK position, spawning area and Minecraft version. The calculators below help you plan the AFK spot and lighting, and Litematica's layer view makes the build manageable in survival.
