FlatEdit+
by Boxadactle
With FlatEdit+, the superflat creation screen in vanilla world creation gains a reworked layer editor, search filters and preset saving for flat worlds.
What it does
FlatEdit+ replaces the limited layer editing of the superflat screen with an interface for adding, removing, reordering and editing layers, with real-time previews. A settings screen lets players adjust how the superflat customization screen itself behaves. Presets can be saved, reloaded later and exported as .flatedit files to share with others.
The mod suits casual builders and hardcore flatworld crafters alike. Structure and decoration toggles let a player choose which villages, mineshafts, strongholds, lava lakes, frozen top layers, desert wells and other features appear in the world. Worlds made with it work with vanilla Minecraft once the mod is installed, though the mod is required each time such a world is loaded. It needs BoxLib and Fabric API as dependencies. The mod is client-side only and released under the GNU General Public License v3.0 only, and the source code is open source with a public issue tracker.
Files target 1.21 – 26.1.2 across Fabric, Forge, NeoForge and Quilt, and the latest builds, 8.0.0 for 26.1.2 on Fabric, NeoForge and Quilt and 7.0.0 for 1.21.11 on Forge, date from April 2026 and February 2026. Snapshot builds are not listed.

How it compares
Superflat Dimensions is server-required with optional client support, open source under the MIT License and published for 1.19 – 1.21.10 on Fabric, Forge, NeoForge and Quilt. Beatable Superflat is also server-required with optional client support, is not open source and covers 1.21.9 – 26.1. FlatEdit+ is client-side only, so it changes only the world creation screen on the player's side.

Isn't it such a hassle to use external sites just to create custom superflat presets? Have you ever wanted to create custom presets right inside of Minecraft?
