Project Zomboid

Universe

Steam

Supported branches

The Agent takes the dedicated-server app id from the title manifest. Do not guess an app id from an older build.

Operating systems

Windows and Linux. No extra Linux packages are installed for this title.

Both branches require a Windows interactive process. Configure session_username and leave start_server_non_interactive off. See Windows Interactive Processes.

Configuration

The server has a Configuration tab. The editor is key-value.

Both branches can hot-reload a saved configuration. Manager asks only when the Agent reports the configHotReload feature for that server. See Game configuration.

Modding

Steam Workshop mods are available on the Mods tab.

Build 42 changed how Workshop mods are laid out. Read Project Zomboid Build 42 mods before you install mods on a current build.

While the server is running and RCon is connected, Workshop Mod Reconcile can ask the game to check Workshop mods for updates. That check does not replace a restart for a first-time Workshop install.

Ports and control

Game port, query port, and Source RCon port are required. The game port is also used as the Steam A2S query port.
