Cobblemon Server Hosting — RAM, Setup & Multiplayer Guide (2026)
Cobblemon is the Pokémon mod that took over Modrinth — open-source, actively developed, and built for multiplayer from day one. It’s also refreshingly light to host: the official Fabric pack ships with performance mods (Lithium, FerriteCore) already tuned, and Cobblemon’s spawning is ambient rather than AI-heavy. If DawnCraft is the demanding end of modded hosting, Cobblemon is the friendly end.
How much RAM does a Cobblemon server need?
| Players | RAM |
|---|---|
| 2–4 friends | 4 GB |
| 5–10 players | 6 GB |
| Public community | 8 GB+ |
Cobblemon’s Pokémon are cheaper to tick than most modded mobs, so player count and explored area drive memory more than the mod itself. The place people get burned is addons: popular datapack/sidemod bundles (Mega Showdown, Myths and Legends, extra regional forms) each add spawn pools and models — a heavily-addon’d server behaves like a pack one size bigger.
Setup: the one rule that matters
Cobblemon versions are strict about client/server matching — a 1.6.x client on a 1.5.x server won’t connect cleanly. So:
- Pick one pack version and pin it. Everyone installs exactly that version; update the server and clients together.
- Use the official pack as the base. Cobblemon Official (Fabric) is the maintained reference — one click on FadeHost installs the whole thing server-side.
- Pregenerate a few thousand blocks (
chunky radius 3000, thenchunky start). Biome-tag spawning means players immediately scatter to hunt specific biomes — pregen makes that painless. - Tune spawns to your taste in
config/cobblemon/main.json:shinyRate(default 8192 — most servers drop it to 4096), spawn caps, and capture multipliers are the settings players actually ask for.
Common Cobblemon server issues
“Incompatible client” on join → version mismatch, almost every time. Compare the exact Cobblemon mod version, not just the pack name.
Pokémon not spawning where expected → spawns are biome-tag driven; a datapack that modifies biomes can silently shrink spawn pools. Test with /checkspawn before blaming the config.
Slow saves with big PC boxes → Pokémon storage lives in world data; enable more frequent backups rather than fewer, larger ones. (FadeHost snapshots run daily by default.)
Cost to run one
A 4 GB Cobblemon server on FadeHost is $5.50/month ($2.50 base + 3 GB extra RAM at $1/GB); the 6 GB community size is $7.50. Every plan includes daily backups and DDoS protection, and the 7-day free trial is enough time to catch a starter, build a gym, and see real multiplayer TPS before paying anything.
