One Survival Island
by Klinbee
One Survival Island generates a single island in an otherwise empty ocean world, set up as a data pack that a server can load for survival play.
What it does
The data pack replaces normal terrain generation with one survival island surrounded by an infinite ocean. Dripstone caves and deep dark areas tend to generate only inland, so they may not appear on the island itself. Mushroom islands are included in the ocean layout. Because the island can be overtaken by a river in some seeds, a player who wants a clean start may need to test a few seeds before settling on a world.
Server owners who want a survival challenge built around scarce land can use the pack directly. The mod version can be set in-game, so the data pack does not have to be configured by hand. Future cave biomes may be added in a later update.
Only the server needs the mod, so players join without installing it. The pack is published for Fabric, Forge, NeoForge and Quilt, with builds covering 1.19 – 26.1, and the code is released under the MIT License as open source.
Key features
Single island world
The world is generated as one survival island with open water on all sides.
Mushroom island layout
Mushroom islands are part of the ocean layout, giving a second kind of landmass to explore.
In-game version setting
The mod version is configured in the game rather than by editing the data pack files.
Seed-dependent terrain
River overlap can change the island in some seeds, so trying different seeds is part of setup.

I may update this in the future to have these cave biomes though if this becomes popular/requested.
