MCDatapacker vs mDirt

MCDatapacker is a Minecraft datapack creator and editor for Linux and Windows. It supports datapacks from Minecraft 1.15 through 1.21.4, with partial support for 1.20.6 through 1.21.4. From its multi-tab interface, users can create or open datapacks, manage files, and edit content. The code editor offers syntax highlighting, error checking for function and JSON files, smart completion for function files, namespaced-ID navigation, and user-defined command syntaxes. Visual editors cover recipes, predicates, loot tables, and item modifiers. Other tools include file and command-usage statistics, raw JSON editing, an advancement-tree viewer, and embedded vanilla datapack files for offline viewing. Dark mode can detect Windows settings automatically. The program is free, with no paid tier required for its core job. Windows users run it from an extracted zip; Linux users run an executable AppImage. The README warns that the program may contain errors and should be used at the user's own risk.

mDirt is a free Windows GUI for creating custom Minecraft datapacks without coding. Guided generators cover blocks, items, recipes, paintings, structures, and equipment, with built-in validation for their fields. The application exports a datapack and resource pack into an exports folder. Structure tools accept Minecraft-generated .nbt files and let users specify details such as spawn rules. Equipment creation includes options such as horse armor, item textures, model textures, and armor points. The README lists full feature support for Minecraft 1.21.4, 1.21.5, 1.21.6, 1.21.7, and 1.21.8. A beta release adds text and potion generators; the potion generator outputs a /give command, while text click and hover events are unsupported. That beta may contain incomplete or unstable features while the interface is refined. mDirt runs on Windows 10 or later, comes as an installer or portable ZIP, requires 130 MB of free disk space, and recommends at least 4 GB of memory. It uses GPL-3.0.
