The record

Purpose: Chunkweave edits structured Minecraft Java Edition data in a browser.
Typed tree editing: The editor presents NBT data as a typed, editable tree and supports searching nested tags and changing typed values.
Supported files: It supports .nbt, .dat, .mca, .mcr, and .schematic files.
World and player data: It can edit level.dat, playerdata, and other compressed NBT containers.
Structures: For structure files, it can inspect structure blocks, entities, palettes, and metadata.
Region browsing: For Anvil regions, it shows populated chunks on a 32×32 map before opening their NBT.
Local processing: The editor parses and rebuilds files in a browser Web Worker; the maker says opened world files are not uploaded, stored, or received by Chunkweave.
Separate-copy export: Edits are rebuilt locally and downloaded as a separate file, leaving the original untouched.
Undo and redo: The workspace includes undo and redo controls before download.
Privacy details: The privacy policy says Railway may process request logs, Google Analytics runs only after analytics-cookie consent, and the site loads fonts from Google Fonts.
Integrations and automation: The maker describes the product as for local manual inspection and editing, and says it is not an automation API.
Support: The maker lists email contact for privacy, support, and product questions.
Audience: The maker describes it as intended for players, map makers, server administrators, and technical creators.
Platform limit: Chunkweave is browser-based and does not offer a Windows, macOS, or Linux desktop installer.
