ukulib

by uku

ukulib is a utility library that supplies shared code for other mods by the same author, and it runs only on the client.

FabricNeoForgeQuiltClient-side onlyMozilla Public License 2.0Open sourceb1.7.3 – 26.3

What it does

Its main part is a configuration system: a simple but thorough way for a mod to declare its settings, together with utilities and widgets for building config screens. Other mods can call these pieces instead of writing their own, which keeps their config menus consistent with each other.

Beyond configuration, the library bundles a range of general Minecraft helpers. It is published for Fabric, NeoForge and Quilt across 34 release versions, with builds covering b1.7.3 – 26.3 and snapshot builds included. The source code is open source under the Mozilla Public License 2.0, and a wiki is linked from the project page.

Thirty-four other mods require ukulib, among them uku's Armor HUD, TotemCounter, BetterHurtCam, Tier Tagger and PotionCounter, so installing any of them also means installing the library. The latest files are 2.2.0+26.3 for Fabric, NeoForge and Quilt, dated 2026-09-15.

Key features

  1. Configuration system

    A declarative way to define mod settings, with the same structure working across the supported loaders.

  2. Config screen widgets

    Ready-made widgets and utilities for building the settings screens that a configuration system needs.

  3. General utilities

    A collection of Minecraft-related helper code that other mods of the author can draw on.

  4. Fabric, NeoForge and Quilt support

    Builds exist for all three loaders, so a mod that uses the library can run on each of them.
