Project Zomboid Server Hosting

Build 42 stable, with a clean compatibility boundary

Project Zomboid Build 42 is now the public stable release. New GHosting servers install that current stable branch automatically, so every player should use the same public Build 42 client before joining.

Build 41 saves do not convert to Build 42. Keep an untouched backup of an established Build 41 world and start a fresh Knox Country for Build 42. Workshop authors also need to mark their items as compatible, so add the group's real mod list during the free trial and verify it before committing to a long campaign.

Why a dedicated Project Zomboid server

Knox County is more fun when it never resets. On a dedicated server your world runs 24/7, so friends can log in on different schedules, bases persist, and the zombie population and loot keep evolving whether or not you are online.

How much RAM for Project Zomboid

Project Zomboid is heavier on memory than it looks, because the server holds explored map cells and every player's simulation in memory. A few players on a fresh map are fine on the entry plan, but heavily explored maps, larger groups, and big mod lists push memory up quickly.

• 2 to 4 players, light mods: entry plan
• Bigger groups or a well-travelled map: mid tier
• Large Workshop mod lists: size up for headroom

Workshop mods without editing config

The painful part of self-hosting Project Zomboid is matching Workshop IDs to Mod IDs by hand in servertest.ini. GHosting does it for you: paste Workshop links into the Mods tab, save, and the server downloads them, resolves the IDs, and hands the mods to players when they join.

Getting that mapping wrong is the classic Zomboid failure: the server starts, looks healthy, and then players hit a mismatched mod list on join. Because the IDs are resolved from the Workshop links rather than typed in, the two lists cannot drift apart.

Ports and connection problems, already handled

Project Zomboid needs separate UDP game and RakNet ports, and optional RCON adds a third TCP port. Self-hosting means every configured port has to agree with the firewall and router, while several servers on one machine need non-overlapping allocations.

On GHosting all three positions are reserved with the server, RCON stays closed unless you set a password, and the address to share is on the dashboard. If you are troubleshooting an existing setup rather than moving, our ports guide covers the two required UDP settings and the -cachedir trap behind most duplicate-server problems.

Settings that matter for a long-running Knox County

The panel exposes the settings groups actually change: join password, player cap up to 64, PvP, public browser listing, and pause when empty. That last one is worth understanding. With it on, the world freezes while nobody is connected, so crops and generators do not burn through fuel overnight. Turn it off when you want the apocalypse to keep grinding whether or not anyone is watching.

Try the real server for 48 hours

A verified account can start one 48-hour Survivor trial with no payment card and no automatic renewal, subject to available capacity. It is the real server with the real panel, console, Mods tab and file access rather than a stripped demo.

Zomboid groups usually stand or fall on the mod list, and two days is enough to load the one your group actually wants, restart, and read the console for the version conflicts that would otherwise surface a week into a save. Continue on a paid term and the same Knox County, mods and settings carry on.

Regions and flexible billing

Pick Europe or North America based on where most of your group plays. Zomboid is more tolerant of distance than a shooter, but a bad route shows up as rubber-banding during a chase, which is exactly when it costs you a character.

Choose pay once or optional automatic renewal. A pay-once server stops at the end of its term, while a subscription renews for the amount and cadence accepted at checkout until you cancel. Renew inside the seven-day grace window and the same save comes straight back. Past that the server is deleted, so download the world first if a run is on hold. Your first server is covered by a 72-hour money-back guarantee.
