Geode
Geode is a Fabric library for Minecraft 1.21.11 that other mod developers use to build their own content, covering registration, math helpers and utility code.
What it does
Geode supplies shared code for mod authors. Its builder-based registration lets a developer declare items, blocks and other registry entries in a compact form, and its math API provides a broader set of calculation helpers than the base game exposes. A set of smaller helper utilities covers common tasks that mods repeat, so each project needs less boilerplate.
The library requires Cardinal Components API, which must be installed alongside it. Geode is published only for Fabric, with a single game version, 1.21.11, and its latest file is 1.2.1 from 2026-02-07, in the beta channel. Every player and the server need a copy of the mod. Geode is open source under the Apache License 2.0 and has public source code and an issue tracker. Legion is one of the mods that require it.

Helper utilities
