Mod Koremods

Koremods, Kotlin Script Framework

Koremods is a utility and library mod for Minecraft Java Edition that lets developers transform Minecraft bytecode through Kotlin scripts. Designed for Forge on both client and server, it offers a focused DSL built around Koffee, an ASM wrapper that makes class, method, field, instruction injection, and bytecode sequence changes more readable.

Its sandboxed execution, Gradle integration, precompiled scripts, remapping tools, and IntelliJ IDEA support with syntax highlighting, autocompletion, and live debugging make advanced mod development more efficient. For a Minecraft server, Koremods is mainly a technical foundation for mods rather than a gameplay content pack. At BoxToPlay, we present it as a practical library for streamlined server customization.
