LagSweeper Datapack

by BibekTheLegend

LagSweeper Datapack is a server-side data pack that removes leftover entities such as dropped items, XP orbs and unused armor stands.

FabricForgeNeoForgeQuiltServer required, client optionalAll rights reserved1.21.5

What it does

The pack cleans up entities that remain in the world after they have stopped serving a purpose, including dropped items, experience orbs and armor stands. Mobs without equipment are also targeted, which reduces the entity count on busy servers. Because it is a data pack, the cleanup runs on the server, and players can join without installing anything.

The pack suits survival worlds, redstone builds and servers where performance matters. Entities carrying specific tags are left alone, so gear and objects meant to stay in place are not affected. The release is published for Fabric, Forge, NeoForge and Quilt, and as a data pack, for 1.21.5 only. Server owners need the 1.21.5 build; the license is All rights reserved and the code is not open source.

Key features

  1. Leftover entity cleanup

    Dropped items, XP orbs and unused armor stands are removed automatically, so they do not pile up over time.

  2. Mob reduction

    Mobs without equipment are cleared out, helping keep the world running smoothly on large or busy maps.

  3. Tag protection

    Entities marked with specific tags are excluded from cleanup, so player-used armor stands and gear stay intact.

What the author says

The pack does not affect players, used armor stands, mobs with gear, or any tagged entities meant to be preserved. It’s especially useful for survival worlds, redstone builds, or servers where performance matters.
