Roughly Enough Items (REI)
by shedaniel
Roughly Enough Items lets players search and browse crafting recipes, usages and items from a single screen without leaving the game.
What it does
Roughly Enough Items, also called REI, is a recipe and item browser. Its screen lists every item the installed mods add, and selecting an entry shows the recipes that craft it and the recipes that use it. Search accepts plain text, tooltip text, tags such as $logs, regular expressions written as r/.../, quoted phrases for names with spaces, and the | operator to match either of two terms.
REI works on either side, and neither side needs it, so a single client or a host that wants recipe lookup for everyone connecting can both run it. The mod requires Architectury API, Cloth Config API and Fabric API on Fabric. It is published for Fabric, Forge, NeoForge and Rift, with files for 1.16.1 – 26.3, and the project is open source under the MIT License. Snapshot builds are published as well.

Compatibility with JEI plugins

How it compares
Just Enough Items (JEI) is the other recipe browser named in this catalog. It is open source under the MIT License and covers 1.8 – 26.3 on Fabric, Forge and NeoForge. Either side can run it, and neither needs it. EMI is open source under the MIT License and is published for Fabric, Forge, NeoForge and Quilt across 1.18.2 – 1.21.1. Players need it on the client, while the server may skip it.

Clean and Customizable. An easy way to browse recipes. Need a server to play with friends? Or don't know how to setup one? Just rent a server that is already configured!
