Blockception Minecraft Bedrock Development vs JsonForge

Blockception Minecraft Bedrock Development is a free extension for developing Minecraft Bedrock Addons and Minecraft Education Edition content. It supports .mcfunction, .json, .lang, and .molang files, with tools specific to each format. JSON features include validation, completions, hovers, signatures, code lens, code actions, and schemas. For .mcfunction, it provides completion, formatting, diagnostics, definition navigation, regions, symbols, syntax highlighting, and validation files; .lang tools include formatting, diagnostics, regions, symbols, and syntax highlighting. The extension can read .mcattributes, .mcdefinitions, and .mcignore project files. A setting adds Education Edition items, blocks, entities, and commands to suggestions and debugging. Other settings toggle diagnostics and selected completion options. During debugging, inline values can show variable lookups in mcfunction and Molang files, but are off by default. The extension is available for Windows, macOS, and Linux. Its earlier repository was archived on September 28, 2025, and points to Minecraft Bedrock Language Server as its successor.

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.
