Free plan

What Neo-Loom is

Neo-Loom is a free Gradle plugin for setting up Minecraft mod development environments with NeoForge and MinecraftForge. It is a fork of Fabric Loom and is heavily based on Architectury Loom. The README lists implemented support for NeoForge 1.21+ and MinecraftForge 1.20.1+.

The plugin supports dependency management and both client and server project scope, including dedicated server support. Developers can package artifacts with Jar-in-Jar, convert ClassTweaker or AccessWidener files to AccessTransformer format, and publish or consume ModDevGradle-compatible Access Transformers and Interface Injections. Devlaunch is also listed as implemented.

The README documents run configurations for NeoForge and MinecraftForge, including server data, client data, and game test server environments. It shows Gradle setup using the Fabric and RelativityMC Maven repositories and the Gradle Plugin Portal, and provides plugin IDs for applying Neo-Loom. The repository identifies the project as MIT licensed and points users to a Discord server for support. Work listed as to-do includes JUnit, production launch tasks, and split-source, client-only, and server-only setups for (Neo)Forge.
