Roughly Enough Items (REI) replaces Minecraft Java's built-in recipe book with a searchable item panel that stays open at the side of any inventory screen. Browse every item and block in your pack, trace crafting recipes forward and backward, and pin frequently used recipes so they stay visible while you work. REI runs on Fabric, Forge, and NeoForge and has supported Java Edition from 1.16.5 through 1.21.

What REI Adds to Minecraft

  • Searchable item and block browser covering every registered item in the pack
  • Recipe view and "used in" view for all supported crafting types
  • Favorites bar and pinnable recipes that stay on screen while you craft
  • Ctrl+Click quick craft to fill a crafting table with ingredients from your inventory
  • Advanced hiding mode to declutter the item list
  • Tag tree browser to inspect item tag groupings and dependencies
  • 80+ configuration options accessible from the in-game settings screen

How to Install Roughly Enough Items

  1. 1.Install Fabric, Forge, or NeoForge for your target Minecraft version.
  2. 2.Download REI from its Modrinth page. Pick the JAR that matches your loader and MC version.
  3. 3.Download Architectury API and Cloth Config API from Modrinth. Both are required dependencies.
  4. 4.Place all three JARs in the mods folder of your Minecraft instance.
  5. 5.Launch the game. REI's item panel appears on the right side of any inventory screen.

Client and Server Installation

REI is optional on both client and server. Most players install it client-only and the item browser works without any server component. Installing REI on a server adds server-side recipe registration for mods that hook into REI's plugin API, which can improve recipe coverage in modpacks where some recipes are registered server-side.

Questions about this entry.

  • How do I install Roughly Enough Items?

    Download REI from its Modrinth page, then download Architectury API and Cloth Config API (both required). Place all three JARs in your mods folder alongside your loader (Fabric, Forge, or NeoForge). Launch and the item panel appears automatically on the right side of any inventory screen.

  • Does REI work on Forge and NeoForge as well as Fabric?

    Yes. REI publishes separate builds for Fabric, Forge, and NeoForge. Download the JAR that matches your loader and Minecraft version from the Modrinth page. Do not mix loader builds in the same instance.

  • Do I need to install REI on the server to use it?

    No. REI works client-only on servers that do not have it installed. The item browser and recipe lookup run locally. Installing it on the server adds server-side recipe registration support but is not required for normal use.

  • What is the difference between REI and JEI?

    Both mods show crafting recipes and item uses in an inventory sidebar. REI offers more built-in configurability (80+ options), a pinnable recipe overlay, quick-craft shortcuts, and a tag tree browser. JEI has broader historic modpack adoption. Which you use typically depends on which your modpack already includes.

  • Which Minecraft version does REI support?

    REI has released builds for Minecraft Java Edition from 1.13 onward. Actively supported versions as of early 2026 include 1.21.x through 1.21.11. Check the Modrinth version list for the latest release for your specific version.
