Utility Core

Server-side quality-of-life and safety patches for NeoForge, packaged as a library.

Most of what Utility Core does is invisible: it stops a negative-damage interaction from crashing the server, resolves conflicting recipes instead of silently picking one, pre-generates chunks while nobody is online. None of it adds content.

Read this first: this is two different things

The repository carries two eras of the same project, and which one you have changes everything — including the licence.

	1.x line	26.2 line
Branches	26.1.2	26.2
Mod id	utility_core	utility_core_admin, utility_core_fixes, utility_core_qol, utility_core_hud
Shape	one monolithic mod	four independent modules
Version	1.11.2	2.3.4 / per module
Licence	All Rights Reserved	MIT

In 2.0.0-beta.1 the monolithic Utility Core was split into independent mods, so you install only the parts you want. That split is also where the licence changed to MIT.

If you are on 26.1.2 you have one mod. If you are on 26.2 you have four. See The Four Modules.

Requirements

Minecraft	26.1.2 or 26.2
Loader	NeoForge
Java	25

At a glance

Dependencies	none
Content added	none — no items, blocks or recipes
Side	almost entirely server-side
Developer API	PolymorphApi for recipe selection

What it does

• Stops crashes — negative damage from mod interactions is clamped to 0, and OutpostZero infection damage is capped so it cannot kill you before the death event fires.
• Resolves recipe conflicts — when several recipes match the same ingredients, a selector appears in the crafting table instead of the game silently picking one.
• Pre-generates chunks in a spiral while the server is empty.
• Protects the spawn schematic area from breaking, placing, explosions and mob spawns.
• Enforces server rules from a JSON file, applying only what differs from the current value.

Where to start

• Getting Started — install, and pick your line.
• The Four Modules — what each of the four installs.
• Features — everything, with which module owns it.
• Configuration — the config file and the in-game menu.
• Compatibility — dependencies, ports and opt-in features.
• Credits and License — the licence changed between lines.
