Eco Stack Manager
by Kaworru
With Eco Stack Manager installed on a server, item stacks and XP orbs are merged and cleaned up automatically, which reduces lag on busy worlds and large XP farms.
What it does
The mod runs entirely on the server, so players connect without installing anything and client-side performance is not affected. It combines item stacks, for example 64 coal into a single coal stack, and removes older excessive items from the world on a schedule the server owner sets. XP orbs within a configured range are merged as well, which helps large XP farms. Fabric API is required on every loader it supports, and the mod needs some additional configuration after installation.
Eco Stack Manager targets Fabric, Forge, NeoForge and Quilt, with files for 16 release versions, 1.18.2 – 1.21.11. The latest builds are version 1.4.1 for 1.21.11, published on 2025-12-31 on the beta channel. The code is released under the MIT License and is open source, and source code, an issue tracker and a wiki are public. Snapshot builds are not part of this card.
Key features
Item stack merging
Items of the same kind on the ground are combined into fewer stacks on the server, reducing entity counts.
Automatic cleanup
Older excessive items are removed from the world at intervals the server owner can set.
XP orb stacking
XP orbs within a specified radius are combined, which lowers the number of entities in large XP farms.
Server-side optimization
All processing happens on the server, so the mod does not add client-side lag.

Use cases
Busy survival servers
Servers with many dropped items can keep entity counts low without manual sweeping.
Large XP farms
Combining orbs in a set range cuts the entity load that large farms create.
Who it’s for: Server owners who run survival or community servers with many dropped items and XP orbs. Players who only join servers do not need to do anything.
