Mod Zeta

Zeta, the Modular Mod Library

Zeta is a supporting library mod for Minecraft Java Edition, designed to help modular gameplay mods share systems and reduce repeated development work. Built as a retooling of Quark’s original module framework, it also succeeds AutoRegLib. Zeta provides infrastructure rather than new blocks, items, mobs, or biomes, so it normally adds no direct gameplay content by itself.

Used on compatible Forge or NeoForge setups, it helps dependent mods function as intended on both client and Minecraft server. Our BoxToPlay experience makes server management straightforward, while Zeta quietly supports the technical foundation behind richer modded gameplay.
