How the calculator sizes a Project Zomboid server

Project Zomboid runs in its own container with 2 vCPU. Its memory starts at 4 GB and grows by 1 GB for every 4 players, the way EphemeralHost sizes every Project Zomboid server; the server size is the next one up from your players.

A big modpack or world needs more memory: More power adds 4 GB for +0.15 €/h, only while the server runs.

Project Zomboid servers load mods from the Steam Workshop: up to 40 mods and 8 GB per server.

Server RAM Price per hour
4 slots 5 GB 0.25 €/h
8 slots 6 GB 0.35 €/h
16 slots 8 GB 0.45 €/h
32 slots 12 GB 0.65 €/h
