Anvil UI vs Blockception Minecraft Bedrock Development

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.

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.
