Differentiate
A modding library for Eltrut & Co. Free Minecraft Java mod for 1.21.1, 1.19.2, 1.18.2.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Differentiate is a library mod designed with an emphasis on automation and copyleft licensing. It is being developed for Eltrut & Co. but can be used by anyone.
