Hosting a Factorio server
Factorio is famously well optimised, but a multiplayer server has a specific limit: UPS, or updates per second. As your factory grows, the server has to simulate more, and once it cannot keep up, the whole game slows down for everyone. Single-thread performance is what drives UPS, so a fast CPU matters more than a large plan.
What to compare
- CPU speed. Because Factorio's simulation is largely single-threaded, strong per-core performance keeps UPS high as your base grows. This is the key spec for the game.
- RAM for map size. Larger maps and mega-bases use more memory, so leave headroom as the factory grows.
- Mod support. Mods come from the in-game mod portal, and the server must run the same mods and versions as players. Check the host lets you manage your mod list easily.
- Version control. Server and clients must match the game version. Check the host lets you choose or pin a version, and how quickly they update.
- Save management. Autosaves protect against crashes, and backups protect against mistakes. Look for easy backups, restores and uploads of an existing save.
- Settings access. Map settings, admin lists and player permissions are configured in server files, so direct access or a good panel matters.
- Location. A nearby datacentre keeps latency low for building and combat.

Factorio server hosting FAQ
What is UPS and why does it matter?
UPS is how many times per second the server updates the world. If it drops below normal, the whole game slows down, and a fast CPU helps prevent that.
Do all players need the same mods?
Yes. The server and players must run the same mods and game version.
Can I upload my existing save?
Yes, on most hosts. Check the steps for your provider.
