Island Border
Java mod listed for Minecraft 1.21–26.x. Downloads from the MC Java Mods app on Android.
Visible island boundaries that players can see and respect. Prevents wandering and protects neighboring islands.
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.
