Anyone who has hosted a Satisfactory session from their own PC knows the moment: you alt-tab to check Discord, your laptop fan spools up, and somewhere in the world a friend's conveyor belt starts stuttering. Peer-to-peer co-op is fine for an evening. It is a lousy way to run a factory you actually care about.
If your group has graduated from "let's hop on for a bit" to "let's not lose this save", you need a dedicated server. This guide is the version of the conversation I wish someone had handed me before I picked my first host — what actually matters, what is marketing fluff, and where Satisfactory specifically punishes the wrong choices.
What a dedicated server actually buys you
A dedicated server is not just "the same game, hosted elsewhere". It changes three concrete things:
- The world keeps ticking when you log off, so trains arrive, power loops top up, and overnight production becomes a real thing.
- Every player connects on equal footing instead of one person eating the host penalty.
- The hardware is doing one job. Your gaming PC is no longer trying to render the game and simulate the factory at the same time, which is the silent cause of half the lag people blame on their internet.
If you only ever play together in the same room on the same evening, peer-to-peer is fine. For everything else, the difference shows up within the first week.
Where Satisfactory burns hardware
Satisfactory has a specific shape as a server workload, and most generic "game hosting" advice misses it. Two things matter, in this order.
RAM, and lots of it. A fresh save will sit happily under 6 GB. By the time you have Mk.4 belts crisscrossing a coal plant and a half-built train network, you are pushing 8–10 GB. A late-game world with nuclear, drones, and a serious number of buildings can comfortably eat 12 GB or more. The trap is that this is driven by factory complexity, not player count. Two people building a megabase will burn more memory than ten people who just landed in the grass fields. Pick a plan that gives you room to grow into rather than one that exactly fits your current save.
Single-thread CPU. The simulation is dominated by one thread doing most of the heavy lifting, which means clock speed and IPC matter much more than core count. A modern Ryzen will outrun an older 32-core Xeon for this specific workload, every time. When a host's spec page brags about cores without mentioning the CPU generation, treat that as a red flag.
Disk and bandwidth are basically afterthoughts unless you are running something exotic.
What to actually look for in a host
Skip the marketing checklist. Three things genuinely separate a good Satisfactory host from a bad one.
The first is honest hardware. Modern Ryzen, named on the spec page, ideally with the generation listed. If you have to email support to find out what CPU your server runs on, that is the answer.
The second is backups that live somewhere other than your server's own disk. The game's autosave is not a backup — if the disk goes, the autosave goes with it. You want a separate, automated snapshot you can roll back to without raising a ticket.
The third is people who know the game. Satisfactory has its own quirks (the Network Quality trap below being the obvious one), and a support team whose first reply is "have you tried restarting it" cannot help you with any of them. The fastest way to test this before buying is to ask a specific question — "how do you handle save migrations from older worlds" — and see whether you get a real answer or a copy-paste.
DDoS protection, instant provisioning, and a usable web panel are table stakes at this point. If a host does not have them in 2026, that tells you everything.
Self-host or pay someone?
Self-hosting on your own hardware is free in the same way owning a car is free once you ignore fuel, insurance, parking, and the time you spend on the phone with the breakdown service.
The hidden costs are uptime (your home internet drops, the factory drops with it), networking (residential uploads are usually awful, dynamic IPs are a pain to share with friends, and port forwarding is the single most common reason a "dedicated server" never goes online), and your own attention. When the server falls over at 2am with a managed host, the recovery is usually happening before you even know there was a problem. With self-hosting, you find out when someone messages you in the morning.
If you genuinely enjoy running Linux services as a hobby, self-host. If you want to play Satisfactory, pay someone.
Picking the right plan
The honest version of plan selection is: pick by RAM, ignore everything else, give yourself headroom.
A two-to-four player group through mid-game is comfortable on around 10 GB. A five-to-eight player group running into late game wants closer to 12–16 GB. Anything bigger, or anyone with mega-base ambitions, should start at 16 GB and assume they will want more later. If you are not sure where you sit, round up — the gap between "comfortable" and "out of memory" is much smaller than people expect, and the symptoms of running out are exactly the ones people blame on the host.
Our Satisfactory hosting plans start at 10 GB on Ryzen hardware, which is the floor we picked deliberately because anything below that bottlenecks before the end of mid-game.
A few Satisfactory-specific things worth knowing
Network Quality is set to Low by default on the server, and it is the biggest single reason people think their host is bad. You set it to Ultra on the server and every connecting client sets it to Ultra on their own machine. Do that once and most "lag" complaints quietly evaporate. If you remember nothing else from this article, remember that.
Save files balloon faster than you expect. A factory that feels modest in-game can produce a 100 MB+ save by late game, and you will eventually want to download one for safekeeping or move it between hosts. We have a guide on locating and uploading your save that covers both directions.
Mods on dedicated servers used to be a misery and are now genuinely good. SML is stable, ficsit.app shows server-compatibility flags right on each mod page, and on LOW.MS specifically there is a one-click mod manager built into the control panel sidebar — install SML and any mod from ficsit.app without touching SFTP. If your group is mod-curious, factor this into your plan size: a heavily modded server uses noticeably more RAM than a vanilla one.
LOW.MS also ships some additional Game.ini tuning by default to head off the most common Satisfactory multiplayer performance issues. You should not need to touch the config to get a smooth experience — leave the defaults alone unless you have a specific reason and know what you are doing.
Getting going
Once you have picked a plan, the setup is short: provision the server, set Network Quality to Ultra, give the world a name and a password, drop in an existing save if you are migrating, and share the IP. Most groups are playing within ten minutes.
The thing nobody tells you is that the real benefit of a dedicated server takes a week to show up. It is the morning you log in and find that your overnight smelter run finished, your power went up because someone added a turbofuel plant on Tuesday, and the world is exactly where you left it. That is when paying for hosting starts to feel obvious instead of indulgent.
