Browser-based NBT workflow

A browser-based alternative to NBTExplorer.

Chunkweave is for people who want a focused, installation-free way to inspect Minecraft Java Edition NBT and region files while keeping the data on their own device.

Files are parsed and rebuilt locally in your browser. Nothing is uploaded to Chunkweave.

Choose by workflow

Browser convenience or an installed desktop tool?

NBTExplorer is a long-established desktop application. Chunkweave is a separate product built around a modern browser workspace. Both approaches can keep file processing local, but they fit different preferences.

What Chunkweave emphasizes

No installer

Start from the website without managing a platform-specific application package.

Local processing

The browser parses and rebuilds supported files without sending their contents to Chunkweave.

One focused workspace

Inspect NBT trees and open populated chunks from Anvil or legacy region containers.

Common questions

Frequently asked questions

Is Chunkweave the same project as NBTExplorer?

No. Chunkweave is an independent browser-based editor and is not affiliated with, endorsed by, or a version of NBTExplorer.

Do I need to install Chunkweave?

No. Chunkweave runs in a modern web browser and processes supported files locally on your device.

Which file formats can Chunkweave open?

The current release supports .nbt, .dat, .mca, .mcr, and .schematic files used by Minecraft Java Edition workflows.

When might a desktop editor still be preferable?

A desktop editor may be a better fit when you need an established native workflow, offline access after installation, or capabilities that are not available in Chunkweave.

Ready when your file is

Inspect the structure before you change it.

Open a supported Minecraft Java Edition file, stage edits, and export a separate copy without sending world data to a server.
