Nether Sky Block
by DubheStudios
Players who want a floating-island survival world on a Fabric or Quilt server can use Nether Sky Block, a 1.19 mod that adds a sky world type and a three-dimension setup.
What it does
Nether Sky Block is server-side only, so only the server needs it and players join without installing anything. It requires Fabric API, which must be installed next to it on the server. Builds exist for Fabric and Quilt, and the only game version covered is 1.19. The latest file for both loaders is 1.1.0 for 1.19, dated 2022-07-23.
To set up a world, the server owner installs Fabric 0.14.8 and Fabric API 0.57.0+1.19 on Minecraft Server 1.19, then sets level-type to skyland in server.properties. A new world can also be created with the SkyLand world type and the DataPack added under More World Options. A gamerule command then switches on the mod's Nether Sky Block settings, either from the console or in game once the world is running.
The world it creates has three dimensions, with void around the floating terrain. The source code, issue tracker and wiki are public, and the code is released under the GNU Lesser General Public License v3.0 only, which makes Nether Sky Block open source.
Key features
Skyland world type
A SkyLand world type appears in the world creation screen once the datapack is added, giving a floating-island start.
Server level-type setting
Servers select the same world by setting level-type to skyland in server.properties, without a client step.
Gamerule settings
A gamerule command switches on the mod's Nether Sky Block settings, either from the console or in game.
Three-dimension layout
The world is built from three dimensions surrounded by void, so the islands are the only solid terrain.

Use cases
Who it’s for: Server owners who want a 1.19 floating-island world with a Fabric or Quilt install. Players who join a server running the mod need no installation.
How it compares
Skylands is also server-side only and open source under the MIT License, but it covers 1.19 – 1.20.2 on Fabric and Quilt, so it reaches further into later versions than Nether Sky Block. Skylands over the Sea is open source under the MIT License and runs on Fabric, Forge, NeoForge and Quilt for 1.18.2 – 1.21.10, where it needs the server and leaves clients optional. Aerolith is not open source, is also server-side required, and targets 1.20 – 1.21 on Fabric, Forge and Quilt.
