Spec score 6.6 #33 of 35 in Minecraft World Editors

What it is

Project Lodestone is a free, open-source toolset for editing and converting Minecraft worlds across Java, Bedrock, console, and other editions. It is still in development, with desktop and web user interfaces described for the project. Documentation lists Java, Bedrock, Raspberry Pi, Xbox 360, PlayStation 3 and 4, PlayStation Vita, Wii U, 3DS, Switch, and Classic Javascript Remake. Planned save editing covers player, region, chunk, and level data, while conversion aims to span editions and versions with options such as depth fixing and lighting recalculation. Listed formats include NBT, S-NBT, MCR/MCA, GRF, MCS, ARC, LOC, PCK, COL, FUI, CDB, and VDB. Other roadmap tools include biome, entity and block-entity, hex, LevelDB, datapack, and map-item editors. libLodestone provides file reading, writing, and conversion for many editions and versions, including Java, Legacy Console, New Nintendo 3DS, and classic.minecraft.net worlds. The app roadmap treats user-facing loading and exporting as planned work. Some converter versions are unavailable in the app, and many listed versions are expected rather than completed support. The project uses an LGPL-3.0 license and is not an official Microsoft, Minecraft, or Mojang Studios product.
