Epic Modded Adventures Await: How to Make a Modded Minecraft Server with Forge (2026 Guide)

Tired of plain vanilla Minecraft? Learning how to make a modded Minecraft server opens up a whole new world of possibilities—think massive tech machines, magical spells, new biomes, and endless customization. Whether you want to play a heavy modpack with friends or build a private server for creative chaos, this straightforward guide shows you exactly how to make a modded Minecraft server using Forge, the most popular and reliable mod loader for 2026.

We’ll focus on self-hosting on your own computer (perfect for full control and no extra costs). The process is beginner-friendly, and by the end, you’ll have a fully functional modded server running Minecraft 1.21 or newer. Let’s dive in!

Quick Prep: What You’ll Need Before Starting

Before you learn how to make a modded Minecraft server, make sure your setup can handle it:

  • Hardware: At least 8 GB of RAM for small groups; more if you’re running heavy mods. A decent CPU helps prevent lag.
  • Internet: A stable connection is key, especially if friends are joining from afar.
  • Java: Minecraft 1.21 requires Java 21 (JDK 21).

Step 1: Install Java 21

Most modded servers in 2026 need the latest Java version for compatibility and performance.

  1. Head to the official Oracle website and download JDK 21 for your operating system.
  2. Run the installer and follow the prompts.
  3. Open Command Prompt (Windows) or Terminal (Mac/Linux) and type java -version to confirm it shows version 21.

Without the correct Java, your server won’t even start—so this step is crucial when figuring out how to make a modded Minecraft server.

Step 2: Download the Vanilla Minecraft Server Files

You need the base server before adding Forge.

  1. Go to the official Minecraft website (minecraft.net).
  2. Download the server.jar file for version 1.21 (or your chosen version).
  3. Create a new empty folder on your computer (e.g., “Modded Minecraft Server”) and place the server.jar inside.

Step 3: Install Forge for Mod Support

Forge is the go-to mod loader because it supports the widest range of mods and modpacks.

  1. Visit the official Forge website (files.minecraftforge.net).
  2. Download the installer for your exact Minecraft version.
  3. Run the installer and choose “Install server.”
  4. Point it to your server folder and let it finish.

Forge will add all the necessary files for mod support.

Step 4: First Server Launch and EULA Acceptance

  1. In your server folder, find and run the new Forge server file (usually run.bat on Windows or a similar script).
  2. The server will start briefly, create new folders (including a “mods” folder), and then stop.
  3. Open the generated eula.txt file, change false to true, and save.

This accepts Minecraft’s End User License Agreement—required for any server.

Step 5: Add Your Mods

This is where the magic happens!

  1. Go to trusted sites like CurseForge or Modrinth.
  2. Download mod .jar files that match your exact Minecraft and Forge version.
  3. Place all mod files into the newly created “mods” folder in your server directory.
  4. Always download dependencies if a mod requires them.

Pro tip: Start with just one or two mods to test stability before adding a full pack. Matching versions exactly is the biggest key to avoiding crashes when learning how to set up a modded Minecraft server.

Step 6: Customize Server Settings

  1. Run the server once more (it will generate server.properties if it hasn’t already).
  2. Open server.properties in any text editor.
  3. Adjust settings like:
    • motd= (your server’s welcome message)
    • gamemode=
    • difficulty=
    • max-players=
    • spawn-protection=0 (recommended for modded worlds)

Save and close.

Step 7: Launch the Server and Join

  1. Double-click the Forge server file to start it.
  2. Wait for everything to load—modded servers take longer than vanilla.
  3. In your Minecraft launcher:
    • Use the same Forge version profile.
    • Install the exact same mods on your client.
    • Go to Multiplayer → Add Server → Enter localhost → Join.

If friends want to join from other networks, they’ll need your public IP (search “what is my IP” on Google) and you’ll need to set up port forwarding on your router (port 25565). Everyone must have identical mods and Forge version.

Step 8: Maintenance and Best Practices

  • Regularly check for mod and Forge updates.
  • Back up your “world” folder often.
  • Test new mods one at a time.
  • Allocate more RAM if needed by editing your startup script.

Core Takeaways: Why This Works So Well

The heart of how to make a modded Minecraft server comes down to three things:

  1. Matching versions (Minecraft + Forge + Mods) on both server and clients.
  2. Proper Java installation.
  3. Starting small and testing thoroughly.

Follow these steps and you’ll avoid 90% of common issues. Once you’re comfortable with this basic setup, you can expand to full modpacks or even dedicated hosting for 24/7 uptime.

Now go create your dream modded world—happy crafting!
