Do I actually need JEI, or can I skip it?

For most modpacks, JEI is required. A lot of mods depend on JEI's API to display recipes for their machines and crafting stations. Remove JEI and those mods either crash on startup or just show blank recipe screens. Even in cases where it's listed as optional, you'll almost always want it because looking up recipes without it means constantly tabbing out to a wiki.

How do I look up a recipe in JEI?

Hover over any item in the JEI panel or anywhere in your inventory and press R. That opens the recipe view for that item and shows every way to craft it. Press U instead to see what the item is used to make. You can click items inside the recipe screen to jump directly to their recipes without going back to the main panel.

JEI isn't showing up in my inventory. What's wrong?

First, check that JEI actually loaded by going to the main menu and looking for a mod list button. If it's listed there, open your inventory and check your GUI scale settings since a very large GUI can push the JEI panel off screen. Also confirm you're in an actual world, not just the title screen. If the panel still doesn't appear, you likely have a version mismatch between your JEI file and your Minecraft version or mod loader. Re-download the correct version.

What's the difference between JEI, REI, and EMI?

JEI is the original and has the widest mod support. REI (Roughly Enough Items) and EMI are alternatives with different UIs and some extra features, but mod compatibility is less consistent. If a mod's description says it supports JEI, it doesn't necessarily have REI or EMI integration. For regular modpack play, JEI is the safe default. REI and EMI are worth considering if you have a specific reason, but you may find some mod recipes don't show up correctly.

Can I use JEI to give myself items?

Yes, through cheat mode, but it's disabled by default. Click the wrench icon in the JEI item panel to open the config, then toggle cheat mode on. You need to be in creative mode or have operator permissions on a server for it to actually work. In a regular survival world without op, the toggle won't do anything.

Just Enough Items (JEI) Mod - Recipe Viewer

Download Just Enough Items from Modrinth

Just Enough Items, almost always called JEI, is a mod by mezz that adds an item browser and recipe viewer directly inside Minecraft. Open your inventory, see a panel full of every item in the game, type in the search bar, and instantly pull up crafting recipes for anything you click.

That sounds simple enough, but there’s a bigger reason JEI is in nearly every modpack: hundreds of mods use JEI’s API to register their own custom recipe types. Machines, multiblocks, infusers, presses, smelters, all the special crafting methods mods add, they hook into JEI so you can look them up from inside the game. Without JEI installed, those mods either refuse to load or just show no recipe information at all. At this point JEI is less a convenience mod and more a core dependency.

What JEI Does

Item and Recipe Browser

The right side of your inventory screen becomes an item panel when JEI is installed. Every item in the game, including items added by other mods, shows up there. Hover over any item and press R to see all the ways to craft it. Press U to see what that item is used to make. That two-key workflow handles most of what you’ll actually use JEI for day to day, and you can click through recipe screens to chain into related recipes without going back to the panel.

Mod Recipe Integration

This is the part that makes JEI genuinely important. Mods like Create, Thermal Expansion, Applied Energistics 2, Mekanism, Tinkers Construct, and literally hundreds of others register their crafting stations and machines with JEI. When you want to know what goes in a Pulverizer, a Metallurgic Infuser, or a Mechanical Press, you look it up in JEI exactly the same way you’d look up a crafting table recipe. No wiki, no guessing, no leaving the game.

Search and Filter

The search bar at the bottom of the item panel is quick and flexible. Type a partial name and it filters immediately. Use the @ prefix followed by a mod name to show only items from that mod, so @create shows just Create mod items. You can also search by tooltip text using #. Useful when you’re deep in one mod and want to stay focused without scrolling through thousands of items.

Bookmarks

Press A on any item to bookmark it. Bookmarks appear in a separate panel so you can keep a short list of things you’re working toward. Handy when you’re planning a build and want quick access to a few specific recipes without clicking through the panel each time.

Cheat Mode

JEI includes an optional cheat mode that lets you click items in the panel to spawn them in your inventory. It’s off by default and requires creative mode or operator permissions on a server. You toggle it from the JEI config menu (the wrench icon in the item panel). Not something you’d use in a normal survival run, but it’s there for testing and server admin work.

Supported Versions and Mod Loaders

JEI runs on Minecraft Forge, Fabric, and NeoForge. Builds exist going back to Minecraft 1.7.10, though anything below 1.16.5 is not actively maintained. Most players are running JEI on 1.19.2, 1.20.1, or 1.21.x, and all of those have stable, well-supported builds.

Pay attention to the version label when you download. JEI files are marked with both the Minecraft version and the mod loader, so grabbing a Forge build when you’re running Fabric (or vice versa) won’t work. Double-check both before downloading.

How to Install JEI

Set up a mod loader first if you haven’t already. JEI works on Forge, Fabric, and NeoForge. Pick the one your other mods use and follow the setup guide for Forge, Fabric, or NeoForge.
Download JEI using the button on this page. Make sure the Minecraft version and mod loader match exactly what you have installed.
Find your Minecraft folder. On Windows, press Win + R, type %appdata%\.minecraft, and press Enter. On Mac, open Finder and go to ~/Library/Application Support/minecraft.
Open the mods folder inside your Minecraft directory. If the folder doesn’t exist, create it.
Move the downloaded JEI .jar file into the mods folder.
Launch Minecraft using your mod loader profile. JEI loads automatically with no extra configuration needed.
Load into a world and open your inventory. The JEI item panel will appear on the right side of the screen.

If you need a full walkthrough of the mod installation process, the mod installation guide covers everything from the launcher setup to dropping files in the right folder.
