Datapack Editor vs Kore

Datapack Editor is a free creator and editor for Minecraft datapacks. It supports Minecraft 1.20.2–1.20.6, corresponding to datapack versions 18–41, and provides syntax highlighting, error checking, and suggestions and completion for mcFunction and JSON files, including nested constructs. Users can open or create projects, validate mcFunction and JSON files, and work across multiple roots. Projects can declare datapack dependencies in dependencies.json. Navigation and editing features include Ctrl-click symbol navigation, multiple tabs and views, quick file opening, and search across files. Custom themes and plugins are supported. Windows users download and extract a ZIP, then run start.cmd; Linux instructions say to extract the ZIP and run the Datapack Editor file. The listed Linux distribution is Debian. macOS support is experimental, and users must build the app themselves. The repository lists an Apache-2.0 license. The README warns that Avast, AVG, and Zillya may flag the Windows executable, describing those alerts as false positives.

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.
