What a Project Zomboid server needs
Project Zomboid is a game that gets heavier the longer you play. Memory use follows how much of the Knox County map has been loaded, how many zombies are active, and above all how many mods you run. Build 42 also uses noticeably more memory than Build 41, so a plan that was comfortable a while ago may now be tight.
What to compare
- RAM for your build and mods. Community guidance suggests around 6 to 8 GB for a small vanilla Build 42 group, 8 to 10 GB for a medium server, and 12 to 16 GB for larger communities or heavy mod lists. Big overhaul mods can roughly double vanilla memory use.
- Steam Workshop support. Each mod needs its Workshop ID and its Mod ID in the server config, so pick a host that makes adding, ordering and removing mods simple.
- Build choice. Build 41 and Build 42 are not interchangeable for saves and mods. Check whether the host lets you choose the build you play.
- Config access. Zombie settings, loot, sandbox options and whitelists live in server files, so direct file access or a good panel is valuable.
- Backups. Characters and bases can be hours of work. Automatic backups and easy restores are worth more than a small saving.
- Location and uptime. Choose a datacentre close to your players and check the provider's support coverage.
