Superflat Dimensions
by Klinbee
Superflat Dimensions creates flat datapack dimensions for the Overworld, Nether and End, with structures and biomes placed on the flat surface.
What it does
Collection datapacks generate superflat versions of the Overworld, Nether and End. Each dimension can carry structures, biomes, trees, foliage, caves and ores, so the flat world is not empty. The preset is modeled after Classic Superflat, and the result is meant to match Classic Superflat Dimensions, including trees and other biome features.
Because the mod is a datapack collection, it changes world generation without new blocks or items. Vanilla hardcoded rules still apply: phantoms spawn only above Y=63, and most aquatic mobs spawn between Y=50 and Y=63. Datapacks allow custom superflat presets, but a preset can only use one biome, and changes to terrain outside the preset must be made globally, so a change to structure or feature generation affects every preset.
The server needs the mod, and clients can join without it. Files are published for Fabric, Forge, NeoForge and Quilt, and the datapack is also available for servers that load datapacks directly. Game versions run 1.19 – 1.21.10, and snapshot builds are published. The code is released under the MIT License and is open source.
Key features
Superflat Overworld, Nether and End
Each of the three vanilla dimensions is generated as a flat world, with its own terrain layers.
Structures and biomes
Structures and biomes are placed on the superflat surface, so exploration still has landmarks.
Trees, caves and ores
Trees, foliage, caves and ores generate in the flat dimensions, following the Classic Superflat preset.
Single-biome presets
Each custom superflat preset uses one biome, which limits the variety of a single preset.

How it compares
The Void Dimension runs on the server alone, is not open source and covers 1.20.1 – 26.3 for Fabric, Forge and NeoForge. Higher Heights is needed on the server, with the client optional; it is released under the MIT License and has builds for 1.17 – 26.3 on Fabric, Forge, NeoForge and Quilt. Superflat Revamped is also optional on the client, is not open source and covers only 1.21.4 on Fabric and Forge.

What the author says
Why does it replace the default overworld, and why can't it use a preset? Datapacks allow creators to edit many things in Minecraft, but some things are hardcoded, meaning they require a mod to change. Datapacks do allow for custom superflat presets, but unfortunately they only allow for single-biome worlds…
