Datapack Editor vs mDirt

Datapack Editor is a free creator and editor for Minecraft datapacks. It supports Minecraft 1.20.2–1.20.6, corresponding to datapack versions 18–41, and provides syntax highlighting, error checking, and suggestions and completion for mcFunction and JSON files, including nested constructs. Users can open or create projects, validate mcFunction and JSON files, and work across multiple roots. Projects can declare datapack dependencies in dependencies.json. Navigation and editing features include Ctrl-click symbol navigation, multiple tabs and views, quick file opening, and search across files. Custom themes and plugins are supported. Windows users download and extract a ZIP, then run start.cmd; Linux instructions say to extract the ZIP and run the Datapack Editor file. The listed Linux distribution is Debian. macOS support is experimental, and users must build the app themselves. The repository lists an Apache-2.0 license. The README warns that Avast, AVG, and Zillya may flag the Windows executable, describing those alerts as false positives.

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.
