Side by side
JMC vs Kore
Both stand on minecraft datapack generators. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan LinuxWindows
Pick JMC if you create Minecraft datapacks and want to write functions using its extension language before compiling them into a pack. Look elsewhere if you need a currently available Windows .exe; the v1.2.19 release removed it and directs users to Python.

Kore adds typed, build-time datapack generation to Kotlin workflows while producing ordinary datapack files. Its current scope excludes resource pack assets and bundled mod bindings.
