FEATURES

Everything you need to build professional Minecraft mods

Multi-Version

Support 10+ Minecraft versions from one codebase. Share code and assets across versions with intelligent inheritance.

Multi-Loader

Build for Fabric, Forge, and NeoForge simultaneously. Platform abstractions keep your code clean and portable.

Asset Packs

Define textures, models, and data once. Inherit and override across versions. No more copy-paste hell.

Zero Config

Convention over configuration. Sensible defaults get you building immediately. Customize when needed.

Fast Builds

Incremental compilation with Gradle caching. Only rebuild what changed. Deploy in seconds, not minutes.

Testing Built-in

Co-located tests with your code. Run tests across all loaders and versions. Catch bugs before release.
