Hosting a Minecraft modpack server requires more resources than vanilla. The specific requirements depend on the modpack, player count, and mod complexity.
If you want the server running without the manual steps below, our modpack server hosting installs packs from CurseForge or Modrinth in one click, with NeoForge, Forge and Fabric supported.

FAQ
How much RAM does a modpack server need?
Light packs: 4-6 GB. For a heavy pack like ATM10 we recommend 12 GB for 1 to 5 players, 16 GB for 5 to 15 and 32 GB for 15 or more. The official ATM10 server files set an 8GB Java heap (-Xmx8G), so raise it to fit your plan.
Can I run modpacks on a free host? Most modpacks need more RAM than free hosts provide. Paid hosting starting at a few euros per month is recommended.
Do I need a specific Java version? Yes. Modern modpacks (1.20.5+) require Java 21. Older packs may use Java 17 or 8.
