OmniIsle
by hack337
Players who want a bounded survival map can use OmniIsle, which turns the Overworld into a single island and keeps biomes and structures inside its shape.
What it does
Overworld generation is contained within one island, and biomes and structures are placed inside that shape. Past the shoreline, an endless and very deep ocean continues, and the world carries on normally rather than stopping at a fixed edge. Players pick the OmniIsle world type when creating a new world, then adjust the island under the Open World Type settings.
An in-game visual editor lets a server owner choose a preset shape or draw a fully custom island before the world is generated, so no world generation files need manual editing. Dedicated servers can use a separate GUI editor outside Minecraft that creates and edits island layouts and can generate an outline from an image. The mod requires Fabric API. Files are published for Fabric and NeoForge across 4 release versions, 1.20.1 – 26.2, and the code is released under the GNU General Public License v3.0 only, so it is open source.

What the author says
OmniIsle changes the Overworld into one large, customizable island while keeping its biomes and structures available within the generated world. Beyond the island lies an infinite, extremely deep ocean, so the world still continues normally instead of ending at an artificial border.
