Mod loaders

Fabric
Lightweight, modular loader. Usually first to support new game versions.
Forge
Long-running loader with the largest catalogue of older mods.
NeoForge
Community fork of Forge, used for 1.20.1 and newer.
Quilt
Fork of Fabric. Runs most Fabric mods as well as its own.
Other loaders
Smaller and legacy loaders listed on Modrinth.
