MLEM API

by Juniper

MLEM API is a Juniper library for building mods that run on Fabric, NeoForge and Quilt from one codebase.

FabricNeoForgeQuiltClient or server, optionalMozilla Public License 2.0Open source26.1.2

What it does

MLEM API is a lightweight wrapper over the Fabric and NeoForge APIs, so a developer can write one multiloader mod instead of separate versions. The project ships with a starting template that developers can copy and modify as a base for their own mods, and the wiki documents the features and how to implement them. Players do not use the library directly; it is a dependency for other mods, and Vanilla Notebook is listed as requiring it. It has no other dependencies.

Files cover game version 26.1.2 only, with the latest 0.1.1 build published on 2026-04-19 in the beta channel for each loader. Either side can run it, and neither needs it, and the code is released under the Mozilla Public License 2.0, so it is open source. Source code and a wiki are linked from the project.

What the author says

MLEM is a lightweight modding API used for developing multiloader Fabric/Neoforge mods, a simple wrapper over Neoforge and Fabric APIs. If you're a player, this mod will do nothing on its own - It's only a dependency for other mods.
