The Satisfactory Dedicated Server runs the planetary open world and vast conveyor automation and power networks independently of clients, 24 hours a day. Space Elevator assembly progress and coal and nuclear power cycles can continue whether group members are online or not. This article covers current server setup, ports, initial claiming and authentication, and operations tuning.
1. Server hardware baseline
| Specification | Phase 1 |
Phase 4~5 industrial megacomplex |
|---|---|---|
| CPU | 4 cores / 3.4GHz+ | 8 cores / 3.8GHz+ with high single-core performance |
| Memory (RAM) | 12 GB physical RAM | 24 GB ~ 32 GB physical RAM |
| Storage | 30 GB NVMe SSD | 80 GB NVMe SSD |
| Upload bandwidth | 10 Mbps dedicated | 30 Mbps dedicated |
2. Install the dedicated server with SteamCMD
Download the dedicated server anonymously through SteamCMD (AppID 1690800):
steamcmd +login anonymous +app_update 1690800 validate +quit
After the download, the Windows executable is:
Engine/Binaries/Win64/FactoryServer-Win64-Shipping-Cmd.exe (or call FactoryServer.exe in the root directly).
3. Unified network port planning
With the 1.0 architecture, the official networking stack was redesigned, replacing the separate early ports 15000 / 15777 with:
| Port | Protocol | Purpose | Router forwarding |
|---|---|---|---|
| 7777 | UDP / TCP | Unified game connection data and query port (Game & Query) | Required (TCP+UDP) |
| 8888 | TCP | Reliable HTTPS/TLS certificate management and Web API communication | Required (TCP) |
4. Claim the server from the client for the first time
Rather than manually writing plaintext passwords in configuration, Satisfactory uses secure client certificate claiming:
- Start the server console.
- Launch the client and select Server Manager in the main menu.
- Select Add Server, enter the server's LAN or public IP, and keep port
7777. - The client detects an unclaimed server and prompts you to set the Server Name and create an Admin Password.
- After claiming, create a new world or load an existing single-player save directly in the graphical interface.
5. Choose an approach: manual configuration or LanGame Server Manager (LGSM)
Manual Satisfactory maintenance involves TLS certificate chains, batch command-line arguments, and rotating archives of giant saves.
We recommend the official open-source dedicated server management platform to automate routine administration:
- Tool overview and client: LanGame Server Manager (LGSM) product page
- Open-source repository: GitHub - SZSLGJCOM/LanGame-Server-Manager
LGSM features:
- Unified port connectivity diagnostics: Checks 7777 (TCP/UDP) and 8888 (TCP) in one click and prevents port conflicts automatically.
- Giant world snapshot management: Supports custom backup schedules and complete one-click restore points before extensive power grid reorganization or demolition.
- Memory overload watchdog: Monitors server memory trends and supports unattended, smooth memory cleanup while the server is empty.
- Live log filtering and analysis: Highlights factory warnings and network disconnections to help administrators locate problems precisely.
