How to Install Modpacks on Your Minecraft Server

Install modpacks to add hundreds of mods working together on your server.

​
Automatic Installation

  1. Go to the Modpacks tab
  2. Search for the modpack you want
  3. Click Install next to your chosen modpack
  4. The modpack will install automatically with the correct Forge version

​
Manual Installation

If your modpack isn’t in the automatic installer:
  1. Upload the modpack:
  2. Install Forge:
    • Find the required Forge version in the modpack’s readme (e.g., 43.2.14)
    • Go to Startup tab and enter the version (e.g., 1.19.1-43.2.14)
    • Delete all files except the modpack archive
    • Go to Settings tab and click Reinstall
  3. Unpack the modpack:
    • Start the server once to generate files
    • Click the three dots next to the archive and click Unarchive
    • Start the server again
First startup with a modpack can take longer than usual.

FAQ

  1. Go into the unarchived folder and select all files
  2. Click the three dots and click Archive
  3. Move the archive up one folder (click Move and add ../ before the filename)
  4. Click Unarchive to extract files to the main folder
The archive may be corrupted. Re-upload it or download it again from the modpack site.
Follow the same steps but upload your own archive. Package it with mod files and any custom configuration files.
Leave the Forge Version field empty. Instead, enter the Minecraft version (e.g., 1.16.5) in the Minecraft Version field to install the latest recommended build.
