JsonForge vs McpeTool

JsonForge is a visual editor for building Minecraft Bedrock JSON UI screens and exporting UI for resource packs. It runs in modern browsers and as a native Electron application on Windows, macOS and Linux. Users can place interface elements on a canvas, adjust their properties, add textures and inspect JSON. The editor includes 10 element types, such as panels, images, labels, buttons, toggles and custom elements. Its workspace has dockable Toolbox, Hierarchy, Canvas, Properties, Textures, Bindings and JSON Preview panels. The canvas uses anchors and the game’s nine-slice texture behavior, with an Edit/Preview toggle. Export targets include form screens, HUD overlays and restyled vanilla scoreboards, with .mcaddon or .mcpack output as applicable. The app includes five ore-UI texture sets and Minecraft fonts. Projects can be saved as .jfproject bundles with an element tree, bindings and textures, or imported and exported as raw Minecraft Bedrock JSON UI .json files. The desktop app can locate worlds on the machine and install exported packs into resource and behavior pack folders. JsonForge is open source under the MIT license. Its guide notes that resource packs cannot create new values that the game does not draw.

McpeTool is a free, offline utility for reading and writing Minecraft Bedrock Edition world data. Its command-line interface and local HTTP API provide get, put, and delete operations. Database commands list, retrieve, write, and delete key/value pairs in a world’s LevelDB store. Level-data commands retrieve or replace level.dat contents using JSON, YAML, hex dump, base64, or binary formats. NBT data can be converted to JSON and YAML, and relevant commands accept or produce base64 and binary data. The API starts a local HTTP server and handles GET, PUT, and DELETE requests for database keys. The tool runs on Linux, macOS, and Windows and can be self-hosted or used through its API. It is MIT-licensed and intended as a basic access layer for people building more capable world editors. McpeTool cannot be used while Minecraft is running the world because LevelDB allows only one process at a time. The maker calls it a work in progress, says input validity is not currently checked, and advises backing up worlds before changes.
