Free Guide to Using Mods With NeoForge

What NeoForge Is and How It Works

NeoForge is a tool that lets you modify Minecraft Java Edition. Think of it as a foundation that makes it possible for mods—user-created additions to the game—to run properly. Before NeoForge existed, modders used another tool called Forge. NeoForge came about as a community-driven continuation of that project, maintained by volunteers and independent developers rather than a single company.

At its core, NeoForge changes how Minecraft starts up and runs. It creates what's called a "modding API" (Application Programming Interface). This is basically a set of instructions that tells mods how to communicate with Minecraft's code. Without NeoForge, mods would need to directly change Minecraft's base files in messy, incompatible ways. With NeoForge, modders can write code that works cleanly alongside the original game.

The tool sits between your computer and Minecraft. When you launch the game through NeoForge, it loads Minecraft first, then adds all your mods on top of it. NeoForge handles making sure everything talks to each other correctly. If two mods try to change the same thing, NeoForge coordinates that process so conflicts are minimized.

NeoForge is free and open source. This means anyone can look at the code that runs it, use it without paying, and even contribute improvements. The project is hosted on GitHub, a website where developers share code. As of 2024, NeoForge supports Minecraft versions 1.20.1 and newer, with ongoing support for future versions.

Practical takeaway: NeoForge is a free tool that acts as a bridge between Minecraft and mods. It doesn't cost anything, and you don't need special permission or registration to use it—you just get it from the official source and install it on your computer.

Getting NeoForge Set Up on Your Computer

The first step is getting NeoForge onto your system. Go to the official NeoForge website at neoforged.net. On the main page, you'll see a large button to get the installer. Click it and choose the Minecraft version you want to use. NeoForge releases versions that match Minecraft versions, so if you want to play Minecraft 1.20.4, you get the NeoForge version for 1.20.4.

Once the installer file is on your computer, open it. A window will appear with options. You'll see two main choices: "Install Server" and "Install Client." For playing on your own computer, choose "Install Client." The installer will ask where to put NeoForge files. The default location (usually in your .minecraft folder) works fine for most people. Click the button to confirm, and the installer will run automatically, placing all necessary files in the right spots.

After installation finishes, open your Minecraft launcher. You should see a new profile option that says something like "neoforge" or lists the NeoForge version. Select it and click play. Minecraft will launch, but it might take longer than normal the first time—this is expected because NeoForge is setting things up. You'll see some text in a window behind the game loading. Once the game loads fully, you're ready to use mods.

Common issues at this stage are usually related to Java. Minecraft requires Java to run, and you need a 64-bit version. If the game won't start, check that you have Java installed. You can verify this by opening a command prompt (Windows) or terminal (Mac/Linux) and typing "java -version." If you get an error, you need to install Java from java.com or through your system's software center.

Practical takeaway: Installing NeoForge takes about five minutes. Go to neoforged.net, run the installer, pick "Install Client," and let it finish. Your next Minecraft launch will use NeoForge automatically.

Finding and Installing Mods for NeoForge

Mods are stored and shared on websites dedicated to Minecraft modding. The most popular sites are CurseForge (curseforge.com) and Modrinth (modrinth.com). Both are free and safe. On CurseForge, look for the "Minecraft" section, then filter by "Mods." On Modrinth, the interface is similar—select Minecraft and choose mods from the sidebar.

When you find a mod you like, look for details about which Minecraft and NeoForge versions it supports. This information appears on the mod's page. For example, a mod might say "Supports Minecraft 1.20.4, requires NeoForge." Make sure it matches what you have installed. If you have NeoForge for version 1.20.4, you can only use mods made for version 1.20.4.

To get the mod file, click the download button on the mod's page. The file will be a .jar file (looks like something.jar). Save it to your computer in a specific folder: go to your Minecraft folder (usually in Users > [your username] > AppData > Roaming > .minecraft on Windows, or Library > Application Support > minecraft on Mac). Inside that folder, there's a "mods" folder. Put the .jar file there. If the mods folder doesn't exist, create it yourself.

One important thing: always read the mod description. Some mods work together fine, but others conflict. A mod page will usually list what other mods it works with or depends on. Some mods require "dependencies"—other mods that must be installed first for them to work. For instance, a mod might say "requires Library Mod X." This means you need to get Library Mod X and put it in your mods folder too, before the main mod will work.

Practical takeaway: Find mods on CurseForge or Modrinth, make sure they support your NeoForge version, get the .jar file, and place it in your Minecraft > mods folder. Restart Minecraft to load the new mods.

Managing Mods and Avoiding Common Problems

Once you have several mods, you might want to organize or disable them without deleting the files. The easiest way is using a mod manager. MultiMC and Prism Launcher are free tools that let you create separate "instances" of Minecraft. Each instance is like a different copy of the game with its own set of mods. You can have one instance with building mods, another with adventure mods, and so on. This prevents mods from conflicting because they're not all loaded at once.

Without a mod manager, you can manually disable mods by renaming them. Instead of "modname.jar," rename the file to "modname.jar.disabled." Minecraft won't load disabled files. To turn the mod back on, rename it back to "modname.jar." This method works, but it's tedious if you have many mods.

Conflicts happen when two mods try to change the same thing in Minecraft. Sometimes the game won't start, or you'll get error messages in the launcher console. Check the error text—it often tells you which mod is causing the problem. If you see "mod A conflicts with mod B," try removing one of them temporarily to see if the issue stops. Many mod creators list known conflicts on their pages, so check there first.

Performance is another consideration. Each mod uses computer resources—more mods means slower gameplay, especially on older computers. If the game lags, try removing mods one at a time to find which ones are heavy. Mods that add lots of new worlds, creatures, or visual effects tend to be more demanding. If you want many mods without lag, you might need to upgrade your computer's RAM or graphics card.

Practical takeaway: Use a mod manager like Prism Launcher to keep mods organized in separate instances. If conflicts happen, check mod pages for known issues, and if performance suffers, remove resource-heavy mods.

Understanding Mod Dependencies and Requirements

Many mods depend on other mods to function. These are called "dependencies." A dependency is like a foundation—the main mod is built on top of it and won't work without it. Common dependencies include library mods that provide basic tools other mod
