Knight Lib
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.

KnightLib is a multiloader utility library designed to eliminate code duplication and provide clean, easy-to-use implementations of systems that every mod tends to reinvent from scratch. Built on Jared's multiloader template, fully compatible with Forge, NeoForge, and Fabric.
