Recipe Item Sync

Recipe Item Sync

Recipe Item Sync is a lightweight utility mod that makes custom datapack items and recipes properly visible inside recipe viewers.

Many datapacks create custom items using vanilla ItemStacks, components, loot tables, commands, or custom crafting systems. These items can work perfectly in-game while remaining completely invisible in JEI, REI, or EMI.

Recipe Item Sync v3.0 automatically discovers supported datapack content on the server and synchronizes it to compatible clients, without requiring the datapack itself to be installed client-side.

What it does

• Makes custom datapack items visible in recipe viewers
• Preserves names, lore, CustomModelData, components, custom data, and stack counts
• Synchronizes supported datapack recipes automatically
• Supports deterministic loot-table based virtual items
• Supports compatible custom item-entity crafting systems
• Improves item search, recipe browsing, and modpack usability
• Automatically refreshes synced content after datapack reloads

Recipe Viewer Support

• Minecraft 1.21.1: JEI, REI, and EMI
• Minecraft 26.2: JEI and REI

EMI support on Minecraft 26.2 will be added when a compatible EMI version becomes available.

Perfect for datapacks that use

• CustomModelData items
• Custom components and NBT-style item data
• Loot tables to generate custom items
• Custom crafting or altar systems
• Large collections of virtual datapack items

Server friendly

The datapack itself can remain server-side. Players only need Recipe Item Sync and a supported recipe viewer.

Resource packs are still required client-side if the datapack uses custom textures, models, or translations.

Important to know

• Recipe Item Sync does not register datapack items as normal modded items
• It does not create textures, models, or translations
• Highly custom scripting systems may not always be representable as normal recipes
• The original datapack remains responsible for the item's behavior and appearance

Recipe Item Sync bridges the gap between server-side datapack content and modern recipe viewers.

From simple CustomModelData items to more advanced datapack crafting systems, v3.0 makes custom content much easier for players to discover and use.
