A Satisfactory Dedicated Server is worth it if your factory should stay available permanently and you do not want to run administration, backups, restarts, and support on a home PC. At game-serverhosting, you rent a paid multi-game server for this with technical control, predictable management, and transparent operating procedures.
Requirements
Before you order the server, you should clarify three things: how large your factory is, how many people play regularly, and whether you use mods. Satisfactory scales heavily with world size. Small to medium factories can start with 6 GB RAM, while larger factories or lots of conveyor belts, vehicles, and production chains benefit more from 8 to 12 GB RAM. This is not a guarantee for every world, but a practical planning value from server sizing.
You also need a Satisfactory installation on your PC, access to the in-game Server Manager, and, for existing worlds, the local .sav file. The official Satisfactory wiki documentation for the Dedicated Server lists the current default ports since patch 1.1.0.0 as the default port 7777 for TCP/UDP and the Reliable Messaging port 8888/TCP; older information using 15000 and 15777 no longer applies according to this source since patch 1.0: documentation at satisfactory.wiki.gg
Order a Server
- Go to game-serverhosting
- Choose at least 6 GB RAM for small to medium factories
- Plan for 8–12 GB RAM for large factories
- Start the server after provisioning and wait until it is reachable
The advantage of a rented server is not just the hardware. Reproducible server starts, file access, clear management through the panel, and support are also important if you get stuck with savegames, ports, or configuration. If you are comparing similar co-op setups, you will find more examples for persistent multiplayer worlds in our Rent and Set Up a Valheim Server – Co-op Guide 2026 and in the Rent a Project Zomboid Server – Multiplayer Guide.
First Setup in the Server Manager
Satisfactory is not managed only through configuration files. The first setup happens directly in the game through the Server Manager:
- Start the server and wait briefly until the process is fully running
- Open Satisfactory and open the Server Manager in the main menu
- Add the server using IP and port
- Set an admin password
- Start a new game or select an existing savegame
- Check server name, session settings, and access protection
The admin password is important because without this permission you cannot manage the server reliably. Use your own password that you do not reuse from other services, and share it only with people who are actually allowed to change server settings.
Upload a Savegame
If you want to keep using an existing world, proceed like this:
- Find the local savegame:
%LOCALAPPDATA%\FactoryGame\Saved\SaveGames\<SteamID>\ - Select the matching
.savfile - Upload the file to the server's savegame folder via SFTP or the panel file manager
- Select and load the savegame in the Server Manager
- Create a backup of the current server savegame before overwriting it
Make sure you do not accidentally upload an autosave that is older than your desired progress. A short test is useful: start the server, log in, and check hub location, milestones, and central production lines. Only once these points are correct should you continue playing with multiple players.
Install Mods
For mods, use the Satisfactory Mod Manager:
- Download SMM from ficsit.app
- Select mods in SMM and activate them for the server
- Upload the mods folder to the server via SFTP or the panel file manager
- Restart the server
- Check whether all players have the same mods and compatible versions installed
Mods are the most common reason for connection problems after updates. Therefore, do not blindly update all mods when an important world is running stable. A short maintenance window is better: create a backup, update mods, start the server, test the connection, and only then inform the group.
Ports and Reachability
The older Satisfactory configuration often used these ports:
| Port | Protocol | Use |
|---|---|---|
| 7777 | UDP | Game traffic |
| 15000 | UDP | Beacon service, older configurations |
| 15777 | UDP | Query, older configurations |
For current Dedicated Server versions, you should follow the official documentation: Since patch 1.1.0.0, 7777/TCP, 7777/UDP, and 8888/TCP are described as the defaults. At game-serverhosting, the required ports are managed server-side; classic port forwarding on your home router is not necessary with a rented server. If you compare older guides, always check which Satisfactory version they refer to.
Set Performance Sensibly
Satisfactory is sensitive to world size, production density, and server tick rate. RAM usage increases with factory size; many objects, long conveyor networks, and large megafactories increase the load. For the processor, a high clock speed is often more important than many cores because not every server task can run in parallel arbitrarily. The officially advertised player count and the practically usable player count can differ depending on world state; therefore avoid fixed promises and test with your specific factory.
For the start, this order makes sense: test without mods first, then load the savegame, then increase the player count, and activate mods last. If you are comparing other survival- or crafting-heavy servers, the Rent a 7 Days to Die Server – Multiplayer Guide 2026 and the Rent and Set Up a V Rising Server – Vampire Guide are also helpful.
Check the Result
After setup, the server should be reachable in the Satisfactory Server Manager, have an admin password, and load the correct world. Also check whether manual saving works, whether autosaves are written, and whether all players can join without version or mod conflicts. Do not test only the login, but also a few minutes of gameplay with production, the power grid, and movement through the factory.
Troubleshooting
If the server does not appear, first check the IP, port, and server status in the panel. If players get stuck while loading, check the current port requirements in the official Dedicated Server documentation and whether the server has fully started. For crashes after mod changes, temporarily remove the most recently changed mods and start with a backup. For poor performance, first reduce parallel construction projects, check RAM usage, and plan an upgrade if the world permanently hits limits.
Checks, Limits, and a Safe Way Back
The guide “Rent a Satisfactory Dedicated Server – Multiplayer Guide” applies to the server type described in the article and the version status visible at the time of review. Menu names, available versions, mod or plugin compatibility, and required resources may differ after updates. Therefore, do not transfer any values unchecked to another game, loader, or server version.
Before making changes to the world, savegame, configuration, or extensions, create a backup of the affected files. Then change only one related step and check it with the same client and server version you want to play with later.
| Checkpoint | Expected Result | Abort and Rollback |
|---|---|---|
| Server start | The server reaches the ready-to-use state without a new error message. | In case of startup errors, undo the change and restore the latest backup. |
| Connection test | A test account can connect via the address shown in the panel. | In case of version or connection errors, compare version, port, and firewall rules again. |
| Function test | The specifically changed function works without damaging existing world or game data. | In case of side effects, stop the server and restore backed-up files. |
A successful individual test is not a performance or availability guarantee. World size, mods, plugins, player count, network path, and simultaneous load can change the result. Document the version, change, and test result so you can understand later deviations.
FAQ
How much RAM do I need for a Satisfactory server?
For small to medium factories, 6 GB RAM is a sensible starting point. Large factories with many production lines, vehicles, conveyor belts, or mods should be planned more around 8 to 12 GB.
Where do I set up the server in the game?
You use the Server Manager in the Satisfactory main menu. There you add the server by IP and port, set the admin password, and choose a new or uploaded savegame.
Can I upload my local savegame?
Yes. On Windows, savegames are typically located in %LOCALAPPDATA%\FactoryGame\Saved\SaveGames\<SteamID>\. Upload the desired .sav file via SFTP or the panel file manager and select it in the Server Manager.
Do mods work on a Dedicated Server?
Yes, if server and clients use the same mods in compatible versions. Use the Satisfactory Mod Manager from ficsit.app, create a backup beforehand, and test mod changes before the regular game night.
Do I have to forward ports myself?
With a rented server from game-serverhosting, you do not need to set up home router port forwarding. It is still important to know the ports matching the installed Satisfactory version, especially when comparing with older guides.
What do I do about lag in large factories?
Check RAM usage, mod status, and factory size. If the problems only appear after an expansion or mod update, test with a backup, reduce the latest changes, or plan for more resources.
