Anvil UI vs Bedrocken

Anvil UI is a web-based visual editor for Minecraft Bedrock JSON UI. It loads a resource pack’s JSON UI files, textures, namespaces, and dependencies so users can build interfaces on a canvas without writing JSON. Changes render instantly in a preview that reproduces anchors, nine-slice elements, fonts, and bindings. The editor supports panels, grids, sliders, scroll views, custom renderers, inheritance, interactive states, bindings, and Bedrock animations. Users can create Server Forms, Chest UIs, HUDs, or custom screens from a blank page or template, then save buttons, cards, and menus in a reusable library. The Free plan costs nothing, billed forever, with unlimited UI projects, the full visual editor, live Bedrock preview, and three cloud packs. Creator costs €12 a month, billed monthly, and adds JSON, PNG, and payload exports, full JSON code, premium updates, and up to 50 cloud packs. Founder's Lifetime costs €249, paid once, billed one time, with Creator features forever and up to 100 cloud packs.

Bedrocken is a VS Code extension for Bedrock add-on development. It exports behavior packs, resource packs, and add-ons, and lets you switch projects from a designated projects folder. Open a manifest.json to link behavior and resource packs or add scripts. Autocomplete covers Bedrock identifiers and project content, including components, entity files, recipes, loot tables, localization files, and JSON assets. Commands generate files from presets and provide snippets for simple tasks. Create New Project makes a com.mojang project; its resource pack description defaults to the behavior pack description. Generate supports texture_list.json, sound_definitions.json, item_texture.json, and terrain_texture.json. From block.json, you can choose an item short name or texture path; the chosen path is registered to the item atlas and an item.json is created. Bedrocken is published by Xterionix under GPL-3.0. It is free, with a listed price of free, and requires VS Code compatibility ^1.87.0. It runs on Windows, macOS, and Linux.
