Cobble vs Orca Minecraft Datapack Generator

Cobble is free, open-source software under the MIT License that transpiles .cbl source into data packs for Minecraft Java Edition. Its Python-like language supports functions, indentation, imports, control flow and static type inference for variables, constants and expressions. Output can include .mcfunction files, pack metadata, tags, predicates, advancements, loot tables, recipes, item modifiers, dialogs and other JSON resources. Cobble handles command JSON safety, macro parameters and command validation, with standard-library helpers for events, text, scoreboards, storage, item components, schedules, selectors, positions, bossbars, teams and entities. The command-line workflow covers project initialization, formatting, building, checking, watching, validation, inspection, linking, cleaning and ZIP creation. The stable release installs with cargo install cobble-lang --locked. A browser compiler runs the Rust parser and transpiler through WebAssembly and can download generated files or a data-pack ZIP. The listed target is Minecraft Java Edition 26.1.2 with pack format 101.1. Cobble is pre-1.0 and actively developed, so bugs and API changes may occur.

Orca Minecraft Datapack Generator turns a plain-English description into a Java datapack, creating JSON and mcfunction files, pack.mcmeta, and the folder layout. It supports recipes, loot tables, advancements, gameplay functions, and world-generation tweaks. The product page says the AI validates a pack, loads it onto a test server, and can use error logs to fix functions that fail. Datapacks run on vanilla Minecraft and Paper or Spigot servers without a client-side mod loader or player installation, but they cannot add entirely new items, blocks, or mobs. The free plan includes Orca Fast, 200 starter credits, 200 credits on later UTC sign-in days, free downloads, and an 8 GB test server. Orca Play costs $6.99 a month; Orca Pro costs 9.99 USD for the first month, then $19.99 a month; Orca Max costs $99.99 a month. Orca says it scans generated builds and uploaded files for security risks. Microsoft Azure OpenAI Service processes chat transcripts and build requests; Orca says user content is not used to train models.
