Java mod listed for Minecraft 1.18–1.19. Downloads from the MC Java Mods app on Android.

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.19.2
Minecraft 1.19–1.19.1
Minecraft 1.18.2

⬇ Download for 1.19.3 ⬇ Download for 1.19.2 ⬇ Download for 1.19–1.19.1 ⬇ Download for 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.
