How to Host a Cozy Zen Server (Forge 1.20.1 Setup Guide)
Cozy Zen is a vanilla-plus pack built around building, decorating, farming, fishing, wildlife, and exploration, running on Forge 1.20.1 with richer biomes and charming structures layered over the base game — plus a few hidden surprises if you go looking. Unlike A Cozy Mizuno World's Japanese-cottage focus or the E.A.L Cozy Farming Pack's farming-and-animal specialization, Cozy Zen is the generalist cozy pick, and hosting it cleanly starts with matching its own recommended RAM floor instead of guessing.
Start with an 8 GB RAM floor — that's Cozy Zen's own recommended minimum for Forge 1.20.1, covering the richer biome generation and extra structure data the pack layers on top of vanilla.
Import Cozy Zen from its official modpack listing instead of copying files out of your own client install — that keeps the mod list, configs, and version pins exactly matched to what the pack author shipped, with nothing missing or mismatched.
Watch the console through first boot: Cozy Zen's richer biome and structure generation takes longer on that first chunk-heavy startup than a plain vanilla server, so let it finish loading fully before assuming anything's stuck.
Only invite players once that first boot has completed cleanly with no mod errors in the log — a server that looks "up" mid-generation can still crash the moment players start spreading out to explore.
Take a backup before importing an existing world, updating the loader, or editing configs — Cozy Zen bakes building, decorating, farming, fishing, and exploration progress into one world file, and a bad edit can wipe hours of that work in one go.

CoalHost is built around modpack hosting, which makes Cozy Zen much less annoying to launch correctly.
