Mod AddonsLib

AddonsLib, the compatibility library for Minecraft mods

AddonsLib is a Java Edition Minecraft library designed to simplify block registration between mods. It is especially useful for compatibility projects built around Macaw’s Bridges, Roofs, Fences and similar building mods. Rather than adding new gameplay content on its own, it provides shared code that helps these projects connect blocks and materials more reliably.

Supporting Fabric, Forge and NeoForge on both client and server, AddonsLib can reduce duplicated compatibility code and help avoid technical errors when related mods are updated. It is a discreet but valuable dependency for a modded Minecraft server. At BoxToPlay, we recommend it whenever a modpack relies on several Macaw’s integrations.
