Why Chunkweave exists
Minecraft world data is powerful, but typed tags, nested compounds, large arrays, and region containers can be difficult to inspect safely. Chunkweave provides a focused visual workspace for players, map makers, server administrators, and technical creators who need to understand and adjust that data.
How the editor works
The application reads supported binary formats in a browser Web Worker, presents their typed structure in an editable tree, stages changes, and rebuilds a downloadable copy locally. The first release intentionally avoids accounts, payments, cloud storage, and server-side world uploads.
Trust through clear boundaries
The interface shows what file was opened, which values changed, what is waiting to be saved, and when a new copy is downloaded. The original source file remains outside the editor's control.
Purpose-built product
Chunkweave is developed as a focused product for inspecting and editing Minecraft world data. Its roadmap prioritizes dependable local processing, clear change tracking, and safe exports.
Independent from Minecraft
Chunkweave is an independent community tool. It is not an official Minecraft product and is not approved by or associated with Mojang or Microsoft. Minecraft names and trademarks belong to their respective owners.
