How to make a Project Zomboid server? A step-by-step guide

Setting up a Project Zomboid server can be done two ways: hosting a dedicated server on your own machine (free but technical) or going through a Project Zomboid host (paid, but ready in a few seconds). Here are both, in detail.

Method 1: the dedicated server on your PC

1. Install the dedicated server via Steam

In your Steam library, enable the display of tools, then install Project Zomboid Dedicated Server. A first launch generates the configuration files and asks you to set an administrator password.

2. Configure servertest.ini

The heart of the settings is in servertest.ini: maximum number of players, server password, PvP, whitelist, default port. This is also where mods are declared via the WorkshopItems= and Mods= lines.

3. Set the difficulty with the sandboxvars

The servertest_SandboxVars.lua file controls the zombie population, the spawn rate of resources, the weather, and so on. It's these sandboxvars that define the survival experience for the whole community.

4. Open the ports (the most tedious part)

For your friends to connect from outside, you have to open the ports (16261 over UDP by default, plus the direct port) on your router and share your public IP. This is where most beginners get stuck: dynamic IP, firewall, some ISPs' CGNAT.

The limits of self-hosting

• Your PC has to stay on permanently for the world to remain accessible.
• Project Zomboid is RAM-hungry: it shares the power with your other activities, which causes slowdowns.
• No Anti-DDoS protection: exposing your personal IP is risky.
• Backups, updates and security are entirely up to you.

Method 2: go through a host (the simplest)

A host removes all the technical side: no ports to open, no IP to expose, server online 24/7. At Fly-Serv, creation is instant: the server is delivered in a few seconds with an address ready to share, and the FlyPanel panel edits servertest.ini and the sandboxvars from a clear interface.

Simple rule: for testing a weekend with friends, self-hosting is enough. For a permanent, smooth world, the host saves more time… and often more money.

Conclusion

If you're just starting out or aiming for a stable community, create your Project Zomboid server with Fly-Serv from 3,99 €/month. Once you're online, learn how to install mods on your server to enrich the survival experience.
