Sculptory

Sculptory is an open-source world editor for Minecraft builders, for Fabric 1.21.1. Press B and the game turns into an editor: floating windows, a tool palette, terrain brushes, selections you can fill, copy, turn and stack, schematics, a shared library, scatter, and one undo history for all of it. It works in singleplayer and on dedicated servers, where the server decides who may edit.

Alpha: this is the first public release. Most of it is covered by automated tests, but parts haven't been played much yet. Keep backups of worlds you care about.
