Java mod listed for Minecraft 1.16–1.21. File opened and checked on 19 Oct 2026; downloads from the MC Java Mods app on Android.
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.
Completely revamp survival by changing many features, from tools being viable weapons, to hunger, to the early game, to enchanting … Check Insane's Survival Extra if you want more (1.20.1 only).
