Remap IDs
Remap IDs is a utility for modpack developers that redirects registry IDs across the whole game, with no code required, on Fabric, Forge and NeoForge.
What it does
Blocks, items, fluids, entity types, tags, recipes and loot tables can each be given an alternative ID through simple JSON files, so content from one mod can be rerouted to another without writing a single line of code. Remaps cover seven registry types and are applied deeply, so recipes, loot tables, tags, NBT data, inventories and containers are rewritten automatically.
The mod suits mod migration and ore unification, for example redirecting silver ingots from five different mods to one canonical ID. Its loot and recipe cleanup can rewrite recipes and loot tables that still want the old items, and stored stacks are updated when the world loads. The mod is open source under the GNU General Public License v3.0 only and is published for 1.20.1 and 1.21.1, with the Forge, Fabric and NeoForge files each at version 2.1.0.
Key features
Wildcard bulk remapping
A single pattern rule can remap an entire family of items at once, such as every variant of one material.
Tag-to-item recipe conversion
Tag ingredients in recipes can be replaced with specific items, which makes recipe output predictable.
Chained remap resolution
When one remap targets an ID that is itself remapped, the chain is flattened so the final target is reached directly.
Live reloading
Tag, recipe and loot table remaps can be reapplied on reload, and block, item, fluid and entity remaps take effect at startup.

How it compares
Effectification [Effect Unification] and Attributification [Attribute Unification] both target one registry each, with Fabric, Forge and NeoForge files for 1.20.1 – 1.21.1, are client and server, and are open source under the MIT License. Better Loot is server required with client optional and open source under the MIT License, for Fabric, NeoForge and Quilt. Remap Menu Key is client-side only and open source under the GNU General Public License v3.0 or later, for Fabric and Quilt, so it is a different kind of tool.
