What is Roughly Enough Items?
Roughly Enough Items (REI) by shedaniel is the recipe viewer that grew up on Fabric and now covers Forge and NeoForge too. It descends from the classic NEI lineage and pairs JEI-style recipe lookups with a heavily customizable interface: movable search bar, craftable-only filtering, and a favorites system that goes beyond items.
Fabric-centric packs and performance-focused clients usually ship REI as their default viewer.
Usage and Standout Features
The basics match the genre: R for recipes, U for uses, click items in the overlay list, and use the + button to auto-fill crafting grids.
REI's distinctive touches:
- Favorites panel on the left accepts items plus function shortcuts: weather toggles, game mode switches, and time-set buttons for operators.
- Craftable filter (the hammer icon) hides everything you lack ingredients for.
- Composting and fuel displays show vanilla mechanics most viewers skip.
- Config in-game via Ctrl+left-click on the config button — nearly every element can move, resize, or hide, with a dark mode toggle.
- Search syntax mirrors the genre:
@mod,#tag, and quoted exact matches.
REI needs its companion libraries (Cloth Config, Architectury) — packs handle that automatically.
Roughly Enough Items (REI) FAQ
REI or JEI: which one should I use?
Feature parity is close. REI leads on Fabric support history and interface customization; JEI leads on plugin coverage from older Forge mods. Use whichever your pack ships; running both causes conflicts.
How do I enable cheat mode in REI?
Ctrl+left-click the config button in the overlay (or open the config screen) and toggle Cheating mode; clicking items then gives them directly if you have operator permissions.
What loaders does REI support?
Fabric first-class since Minecraft 1.13, plus Forge and NeoForge builds for recent versions.
