Can I play Build 41 or the Build 42 preview?

Yes. Besides Build 42, Build 41 and the Build 42 preview (unstable) are available as branches. The world is backed up before the switch. Build 41 and Build 42 worlds are not interchangeable.

Do modpacks with a Java agent (ZombieBuddy) work?

Yes. Tested on 25 October 2026 with Build 42.21, ZombieBuddy 2.3.4 and the mods Project Viewpoint and Surface Fix on Flex L: ZombieBuddy starts with the server, both Java mods are loaded, and the setting persists after a game update. Upload ZombieBuddy.jar in the file manager, enter -javaagent:ZombieBuddy.jar as a Java start parameter and approve the Java mods in .zombie_buddy/mod_approvals.json. Java mods require mod support, so Flex M or higher.

How do mods get onto the server?

You enter the Workshop ID and the Mod ID, the server then downloads the mod from the Steam Workshop. Your friends get the same mod via Steam.

Which tier do I need?

The larger the explored area, the sooner the next tier pays off. The tier can be changed at any time.

Does the world keep running when nobody plays?

Optionally not. Then the world stops while nobody is connected.

Can I access the files of my server?

Yes, with the file manager in the customer portal. From Flex M you upload files, edit text files, create folders, rename and delete. With Flex S you view and download the files. Backups and settings files managed by the customer portal are read-only.

How quickly is my server ready?

Usually within minutes. The server is set up automatically, the access details are sent by email.

How long is the contract?

One month. After that the server can be cancelled monthly with one month's notice. There is no setup fee.

Can I play a different game later?

Yes. You switch the game yourself in the customer portal, free of charge and as often as you like. Your Project Zomboid world is kept. When you switch back, the last state is restored.

What happens to my world when I cancel?

Your last save is kept for 90 days after the contract ends. If you order a new Project Zomboid server within that time, it is taken over into the new server.

Where is the server located?

In a data center in Germany. Glowfish has been an owner-managed hosting provider in Munich since 2006.
