UnionLib is a library mod that supplies common code and systems used by Stereowalker’s other Minecraft projects. It is designed to reduce duplicated features while helping companion mods work consistently across Forge, Fabric, NeoForge, and Quilt.
Its toolkit includes registry utilities, configuration support, tooltip integration, version helpers, cosmetic features, and hooks for client and server events. UnionLib does not focus on adding a standalone adventure layer, but quietly supports the mods that depend on it, making it valuable for a stable modded Minecraft server. At BoxToPlay, we recommend it whenever a Stereowalker mod lists UnionLib as a required library.
