Java mod listed for Minecraft 1.18–1.20. 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 Forge only.

Minecraft 1.20–1.20.1Newest
Minecraft 1.18.2

⬇ Download for 1.20–1.20.1 ⬇ 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.

Stratospherical Expansion is a mod which completely overhauls the overworld generation to be made of sky islands. It also features completely reimagined vanilla biomes.
Requires Terrablender

!!! OUTDATED: Use the OG Stratospherical preset in Ecospherical Expansion instead of this mod. Note: That is only available in 1.20.x. Fabric/Forge!!!

There is a dimensional version of this mod which can be found under the files tab of this mod page. It separates this into another dimension instead of overriding the overworld. However, its features are more limited with overall simpler generation. To enter the dimensional version of this mod you must fly to Y420 in the overworld. To return you just fall into the void of the stratospheric dimension.
