Why host Factorio with Multiplayer Rally
Wube ships a free headless server build, and it is tiny: a megabase is bound by CPU, not memory. Space Age keeps the community as active as ever. The kind of game a server should simply never go down for.
- Light server: Factorio fits comfortably on most gaming PCs. Plan on 1-4 GB of free RAM.
- Runs the official Factorio server on Windows, Linux, macOS. We download it from the publisher and keep the runtime patched.
- Your Factorio world stays set up between sessions. The app handles restarts, updates, and the relay link so the squad can drop in whenever you're online.
How hosting Factorio works
- Step 01
Install Multiplayer Rally
One Windows app. It installs and manages the Factorio dedicated server for you. No command line, no config files.
- Step 02
Pick Factorio
We set the ports, the settings, and the restart schedule. You pick the world name and who's allowed in.
- Step 03
Share your link
You get one address your friends paste into the game, and they're in. Nothing to install on their side, no port forwarding on yours.
Factorio hosting questions
Plan on 1-4 GB of free RAM for a friend-group server. Your PC needs that on top of whatever else it's running; the app checks before installing.
34197 (UDP). With Multiplayer Rally you don't forward any of them: the agent makes an outbound connection to our relay, and your friends connect to the relay address.
Yes, that's the whole point. The agent on your PC makes an outbound connection to our relay, so you never touch your router. Your friends connect to the relay address and the traffic is tunneled to your Factorio server. Nothing is exposed to the open internet.
Yes. Each player needs their own copy of Factorio to join your server. We host the server side; the game itself comes from the store like always.
Factorio is in our planned launch catalog. Join the waitlist, pick Factorio as your game, and we'll email you when it's live.
Your PC is the server, so the world is offline until you turn it back on, then it's right where you left it. The agent restarts Factorio for you automatically. An always-on managed tier on our hardware comes later.
