How to Add Mods to Your Project Zomboid Server

## Adding Steam Workshop Mods

Project Zomboid supports Steam Workshop mods on dedicated servers.

## Steps

- Find the mod you want on the Steam Workshop (https://steamcommunity.com/app/108600/workshop/)
- Copy the **Workshop ID** from the mod's URL (the number after )
- In your panel, go to the **Startup** tab
- Add the Workshop ID to the **Workshop Mods** field (separate multiple IDs with semicolons)
- Also add the mod ID to the **Mods** field in the server settings
- Restart the server — it will download the mods automatically

## Important

- All players must also subscribe to the same mods in their Steam client
- Too many mods can increase RAM usage and startup time
- After adding mods, monitor your server's memory usage

## Experiencing Lag After Adding Mods?

**Do not upgrade your plan right away.** Lag is most often caused by the mods themselves or their configuration, not by insufficient server resources.

- Review which mods you've added — some are known to be resource-heavy
- Check your mod configurations for excessive settings (e.g., large spawn rates, high entity counts)
- Remove mods one by one to identify the culprit
- Monitor your RAM and CPU usage in the panel after each change

Only consider upgrading if your server is clean, properly configured, and still consistently hitting resource limits under normal load.
