IntelliJ IDEA vs Neo-Loom

IntelliJ IDEA is an IDE for professional Java and Kotlin development, available on Windows, macOS, and Linux. It offers context-aware completion, static analysis, and automated refactoring. The JVM debugger includes breakpoints, variable inspection, expression evaluation, and step-by-step execution. Gradle and Maven integrations cover building, packaging, testing, and deployment, while version-control support includes Git, Mercurial, Perforce, and Subversion. Users can process GitHub pull requests in the IDE, and plugins from JetBrains Marketplace add support for other languages, frameworks, and technologies. Core Java and Kotlin functionality remains free after the included 30-day Ultimate trial ends. The Ultimate subscription adds advanced tools and integrations and costs $100.00 for the first year, $199.00 for the second year, and $159.00 per year from the third year onward. Listed minimum hardware is a 4-core x86_64 or arm64 CPU, 8 GB total RAM, and 10 GB of disk space. Users can choose in IDE settings whether to share anonymous usage data.

Neo-Loom is a free Gradle plugin for Minecraft mod development environments using NeoForge or MinecraftForge. It is a fork of Fabric Loom and is heavily based on Architectury Loom. Implemented support includes NeoForge 1.21+ and MinecraftForge 1.20.1+. The plugin supports multi-loader projects, dependency management, client and server scope, and dedicated server support. It provides run configurations for NeoForge and MinecraftForge covering server data, client data, and game test server environments. Neo-Loom supports Jar-in-Jar packaging, converts ClassTweaker or AccessWidener files to AccessTransformer format, and supports publishing and consuming ModDevGradle-compatible Access Transformers and Interface Injections. Devlaunch is listed as implemented. Setup uses the Fabric and RelativityMC Maven repositories and the Gradle Plugin Portal, with plugin IDs shown in the README. The repository is MIT licensed and points users to Discord for support. Listed unfinished work includes JUnit, production launch tasks, and split-source, client-only, and server-only setups for (Neo)Forge.
