Modpack Server Hosting

Why Modpacks Need Resources That Are Yours

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.

Memory that is yours solves 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 that memory from you. When storage is Enterprise NVMe, as on the Performance line, 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 a fixed amount of RAM that no other server on the node can touch, on shared cores with SSD storage on the standard line, or on the AMD Ryzen 9 7950X with DDR5 RAM or the AMD Ryzen 9 5900X and Enterprise NVMe on the Performance line. You also get full access to our own panel of our own build with a file manager, so uploading modpacks and adjusting server properties is straightforward. You do not have to upload one at all if you would rather not: the panel installs a whole modpack in one click from Modrinth, CurseForge or Feed The Beast, checks every jar it fetches, and switches the server to the right loader while it does it. A pack too large for a browser upload goes in by pasting its link and letting the machine fetch it itself.

Forge and Fabric Support

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.
