Registry Dumper 3000
Registry Dumper 3000 exports the registries, tags and recipes of the game, along with resource folders, into files on disk, which lets modpack makers see what is actually loaded.
What it does
Modpack makers, datapack creators and mod developers use the mod to see the final state of a game after every mod and datapack has merged. It dumps built-in registries such as blocks, items and fluids, along with runtime registries from the server, including modded ones. Raw tag JSON is written as the resource manager resolves it, so the resolved contents of each tag can be checked after all layers apply. Raw recipe JSON files are copied as well.
The output is configurable: plain text or JSON, optional class names for entries, and a folder layout set in the mod config. A config-driven rule set copies arbitrary datapack folders in raw form and includes a large default ruleset, which helps find hidden resource directories that mods add. Client-side asset dumping exists as an option but starts disabled, because the output is large.
Registry Dumper 3000 requires Architectury API. It runs on client and server and is published for Fabric, Forge, NeoForge and Quilt, with files for 1.20.1 and 1.21.1. The code is not open source; the mod is released under All rights reserved.
