Modpack Server Hosting

Run RLCraft, ATM10, Pixelmon, Create, or any other modpack on hardware that can actually handle it. NVMe storage, dedicated vCPU cores, and enough RAM to keep tick rates stable.

A vanilla Minecraft server can run on 2 GB of RAM without breaking a sweat. Modpacks are a completely different story. When you load 150, 300, or 400+ mods into a single server, every part of the hardware gets pushed harder. The JVM needs more heap memory, the CPU spends more time on block interactions and entity AI, and the disk has to read and write larger chunk files every time a player explores new terrain.

Shared hosting plans that advertise “unlimited” RAM almost always oversell their nodes. Your server ends up competing with dozens of others for the same physical CPU and the same disk throughput. That is fine for a small Paper server, but modpacks punish it. You get lag spikes during world generation, freezes when players open large inventories, and TPS drops that make the game unplayable once a few people start automating things.

Dedicated resources solve the problem at the hardware level. When your server has 8 or 12 GB of RAM that belongs entirely to your instance, there is no neighbor to steal cycles from you. When storage is NVMe-based, chunk generation and region file writes happen faster than the server can queue them. And when you have guaranteed vCPU cores, the tick loop stays at 20 TPS even when multiple players are exploring in different directions.

That is the approach we take at Astroworld. Every plan comes with dedicated vCPU cores, NVMe SSD storage, and a fixed amount of RAM that no other server on the node can touch. You also get full access to a Pterodactyl-based panel with a file manager, so uploading modpacks and adjusting server properties is straightforward.

Most popular modpacks run on Forge, the mod loader that has been the standard since the early days of Minecraft modding. Forge handles the heavy lifting of loading hundreds of mods, resolving dependencies, and patching the base game code so that everything works together. RLCraft, All The Mods 10, Pixelmon, and Vault Hunters all use Forge.

Fabric is the newer alternative. It is lighter-weight and tends to load faster, but its mod ecosystem is smaller. Packs like Fabulously Optimized and some versions of Create use Fabric. If your pack ships with a Fabric server JAR, you can run it on any of our plans the same way you would run Forge.

Either way, the setup process is the same. Upload your server pack through the panel's file manager or via SFTP, set the correct startup JAR, and adjust the RAM allocation in the startup parameters. If you are new to modded servers, our modpack installation guide walks through every step.

Every Astroworld plan includes the Pterodactyl panel with a built-in file manager. You can upload server packs directly through your browser, extract ZIP files on the server itself, and edit configuration files without needing an FTP client. For larger uploads, SFTP access is also available from the panel settings.

Most modpacks on CurseForge and Modrinth publish a “server pack” download that is separate from the client pack. That server pack contains only the mods and config files the server needs. Upload it, extract it, point the startup command to the correct Forge or Fabric JAR, and start the server. First-time startup usually takes a few minutes because the server has to generate configuration files and pre-load mod data.

If you run into issues, the modpack installation guide covers the process step by step. For RAM-related questions, check the RAM guide to figure out which plan fits your pack.
