WT SkyGrid
by whotevatech
WT SkyGrid generates worlds where blocks sit in a 3D grid over a floating void, and the server controls which blocks appear.
What it does
Worlds created with WT SkyGrid start as a three-dimensional grid of blocks suspended in an empty void. Blocks are placed at fixed intervals in four directions, and the spacing and layout can be set in the config. The block pool draws from stone, ores, wood, lava and blocks from the nether and end, and it extends automatically to blocks added by other installed mods.
The grid also carries loot chests, mob spawners and saplings. Chests are scattered with loot from dungeon, mineshaft and temple tables. Spawners appear with a range of mob types. Saplings always generate on a dirt block, and the grow behavior can be adjusted. A whitelist and a blacklist in a simple JSON file decide which blocks enter the pool, and an in-game debug command lists the blocks currently in it.
The mod runs on the server, so players join without installing anything. It works on Fabric and NeoForge for 1.21.1 only, with both loader files dated 2026-04-17 at version 1.2.0. The license is the MIT License, and the code is not open source.

Use cases
Who it’s for: Server owners and survival players who want a world built from a grid over a void, rather than terrain. The mod is for the server side, so only the host needs to configure it.
How it compares
Vanilla SkyGrid is a client mod for Fabric under the Apache License 2.0 and is not open source; it has files for 1.21.8 – 1.21.9 and needs the client, while the server may skip it. Grid World Generator is a server-required Fabric mod under the zlib License, not open source, with files for 1.21.5 – 26.3 and the client optional. WT SkyGrid differs by running server-side only and by supporting both Fabric and NeoForge on 1.21.1.
