Cobblemon.gg - Ultimate Pokemon Experience Server Hosting

Start with 6 GB. That covers the roughly 110 mods and a small group of trainers. Wild Pokemon are full entities with models and AI, so memory and tick time climb when players spread across many biomes at once. If the server stutters, profile it with spark first and raise RAM only when the profile points at memory pressure rather than one misbehaving mod.

Around six players is the sweet spot on the recommended memory. Each active player keeps Pokemon spawning around them, so a group that travels together costs far less than six people hunting in six different biomes. Bigger groups work too, but give the server more RAM and pregenerate a wider area before they arrive.

Back up the world first, because Cobblemon stores every party and PC box inside the save. Then install the new build from the Modpacks tab, start the server once and read the console for mod errors. Ask players to update their client to the same build, since a mismatched mod list blocks them at login.

Yes, through the Files tab or SFTP, as long as each mod targets Fabric for Minecraft 1.21.1. Removing a mod that adds items or blocks can wipe them from the world, and pulling Cobblemon add-ons can affect stored Pokemon, so back up first. A mod that also runs on the client must be added to every player's client as well.

The official Cobblemon modpack stays close to the core mod with a short mod list. Cobblemon.gg layers around 110 mods on top, adding adventure and technology content, so a world lasts longer and the server needs more memory. Pick the official pack for a quick, light server and Cobblemon.gg when you want a fuller journey around catching.

Each Cobblemon battle is resolved on the server by a battle engine that tracks moves, types and abilities turn by turn. One fight is light, but several at once on top of heavy spawning adds up. If a busy evening feels slow, a spark profile shows whether battles, spawning or another mod is the real cost.
