Cobble vs Shulkerscript
Both stand on minecraft datapack generators. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Choose Cobble for Minecraft Java Edition data-pack development with Python-like source, broad resource generation, and both CLI and browser workflows. Its free MIT-licensed model suits open projects. Consider another tool if you need a mature, stable API or want to avoid curl and Java validation requirements.
Visit CobbleChoose Shulkerscript if you want a free, open source language and CLI for creating Minecraft data packs, with function generation and ZIP packaging. Check the annotation requirement before building: at least one function needs a `tick`, `load`, or `deobfuscate` annotation for `.mcfunction` output. The playground and Lua integration are still described as works in progress.

Cobble: what it does well
- Free and open-source under the MIT License
- Python-like syntax with static type inference
- Generates functions, recipes, loot tables, and advancements
- CLI supports building, watching, validation, and ZIP output
- Browser compiler runs through WebAssembly
What to know first
- Pre-1.0 software may contain bugs
- API changes are possible during active development
- Validation may require curl and Java
- Targets Minecraft Java Edition
Shulkerscript: what it does well
- Generates multiple Minecraft function files from one source file.
- Supports imports, tags, conditionals, execute blocks, and embedded Lua.
- CLI watches files and rebuilds projects automatically.
- Can package compiled projects as ZIP archives.
- Browser playground works without installing the CLI.
What to know first
- Builds generate no `.mcfunction` files without a qualifying function annotation.
- Documentation marks the playground and Lua integration as works in progress.
