Kore vs RedScript

Kore is a Kotlin library for generating Minecraft datapacks from code. It runs during the build and produces ordinary datapack files, so the server does not need Kore or a Kore plugin. Its typed game data can catch errors in items, blocks, sounds, and commands before a datapack is reloaded. The site lists 65+ typed commands, 50+ JSON resource types, and 80+ generated registries. Kore supports commands, recipes, loot tables, advancements, custom dimensions, functions, and predicates; Kotlin functions, loops, and variables can also generate repeated content. If its typed DSL does not cover a command, function bodies can include raw command lines. Existing datapacks can be moved over gradually, with handwritten parts continuing to run alongside generated ones. Kore is available as a Maven Central dependency, and the maker recommends a JDK and Kotlin IDE. An optional Gradle plugin can build, link, and reload a datapack on save. A browser playground can generate a datapack ZIP. The project is free and open source.

RedScript is a programming language and toolchain for creating vanilla Minecraft datapacks, compiling code into .mcfunction files. Its datapacks run without mods, and a browser-based playground lets users write code and download a datapack. The language includes variables, functions, control flow, structs, enums, Option and Result types, f-strings, and modules. Minecraft-specific features include load and tick handlers, selectors, and command helpers. Its toolchain covers compilation, type checking, optimization, formatting, linting, testing, and watch mode. An LSP and VS Code extension provide diagnostics, completion, hover details, navigation, snippets, and syntax highlighting. RedScript also supports typed resource declarations and JSON or NBT contributions from files, with collision checks and directory or ZIP output. Static command checks can identify issues, but do not establish behavior on a live Paper server. Dimension and dimension_type resources require reopening the world.
