JsonForge vs Snowstorm

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.

Snowstorm is a custom editor and generator for Minecraft Bedrock Edition particle files. Its web app is available at snowstorm.app, and a Visual Studio Code extension provides another way to edit particle files; that extension requires the name pattern *.particle.json. A Quick Setup tab offers preset particle motions and appearances to get a project started. Files can be added to Minecraft Bedrock resource packs and used in experiences. The project repository identifies JannisX11 as owner, lists a GPL-3.0 license, and says the web app can be hosted locally using a preferred local server. Snowstorm is free, with a listed free version at free. The supplied platform listings include Android, iOS, Linux, macOS, web, Windows, and extension. Snowstorm is also described as a decentralized microproxy network, with client and volunteer-peer uses for censorship circumvention.
