Anvil UI vs bedrockR

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.

bedrockR is a free, open-source visual maker for Minecraft Bedrock add-ons. It runs on Windows and Linux and is intended to make add-on creation less confusing and tedious. Windows downloads provide a portable EXE in a ZIP archive and an MSI installer for 64-bit systems. Linux releases include Debian DEB installers and portable builds for ARM64 and AMD64; the maker says Debian builds can be installed on Chromebook. Universal JAR builds require Java 25, and other Java versions are unsupported. The project wiki includes guides for making a basic item, block and recipe, plus a food tutorial video. bedrockR describes itself as alpha, so features and behavior may change. Feedback is requested through Discord and GitHub issues. Since version a2.0, its add-on creation code can be used in other projects through a Maven library on JitPack; earlier releases do not work there and are discouraged as libraries. The project says it is not associated with Mojang AB or Microsoft Corp.
