Sons of the Forest Dedicated Server: Hardware Requirements and Config for 2026

Sons of the Forest ships a dedicated server tool that is lightweight on RAM but hungry for single-core speed. Official minimums list 4 CPU cores and 8 GB of RAM; in practice a 4-player world idles around 4–6 GB, and an 8-player server with a large built base sits closer to 8–12 GB. The server streams a lot of world data on save and load, so NVMe or SSD-backed storage visibly cuts the worst stutter during world loads.

The game is still receiving content updates, and each update requires the server tool to match the client version — which makes update management and restart scheduling part of the hosting job, not an afterthought. If you are planning a machine for a persistent community world, compare dedicated server plans side by side with an eye on CPU clock speed and SSD storage rather than raw core count.

Realistic hardware sizing for 2026

The dedicated server simulates the island, AI, and building integrity on a small number of threads, so per-core frequency matters more than total cores. The ranges below reflect measured behavior on community servers, not the official minimums.

Players	CPU	RAM	Storage
4	4 cores @ 3 GHz	6 GB	20 GB SSD
8	4–6 cores @ 3.5 GHz	10 GB	30 GB SSD
8 + extensive builds	6+ cores @ 3.5 GHz	12–16 GB	40 GB NVMe

Save files grow as players build; a long-running community world with elaborate structures can exceed 1 GB of save data, so leave headroom on disk and keep backups off the same drive if possible.

Installing and configuring the dedicated server

The server tool is distributed via SteamCMD under app ID 246520 and runs natively on Linux: steamcmd +login anonymous +app_update 246520 +quit, then run the binary from the install directory. On first launch it generates ServerConfig.cfg in the save folder. The settings that matter most:

• ServerName and ServerPassword — set both; an open server gets griefed within hours.
• MaxPlayers — 4 to 8 is the realistic range; above that the simulation degrades noticeably.
• GamePort (default 8766) and QueryPort (default 27016) — both UDP; forward them on your firewall.
• SaveDataPath — point saves at a dedicated directory so backups are a single rsync command.
• GameMode — set it before players join; changing it later resets world rules for everyone.

Keeping a persistent world alive

The dedicated server persists the world when players save in-game and on clean shutdown, so a scheduled restart window every 12–24 hours doubles as a checkpoint. Pair that with hourly backups of the save directory. When the game patches — and it still does regularly in 2026 — update the server tool and restart; clients on the old version cannot join until they update too. For uptime, wrap the server binary in systemd with Restart=on-failure so a crash does not silently take the community offline until someone notices.

Firewall setup is worth getting right up front. The server listens on GamePort (8766 UDP) and QueryPort (27016 UDP); the query port is what the Steam server browser pings, so if you open one and not the other, players can join by direct IP but the server stays invisible in the in-game list. On a rented dedicated box, the host’s firewall is usually the only one in the path — confirm with ss -ulpn that the server is bound to the right interface, then test from an external client before announcing the address to your community.

The case: a six-player persistent base

A group we profiled runs an 8-player world on a dedicated Ryzen 7 box with 32 GB of RAM. The server uses about 9 GB of RAM and two cores at roughly 70 percent during heavy building sessions, with save/load pauses of a few seconds on NVMe storage — on a SATA SSD the same operations took noticeably longer. They keep three daily backup generations and a weekly archive; a corrupted save was restored from a backup in under five minutes. Total admin time is about 30 minutes a week, mostly updates and the restart check.

If that workload matches what you are planning, browse the current InterServer dedicated server lineup — a mid-tier machine with NVMe storage handles this game plus room for a second title.

Size the CPU, then forget it

Sons of the Forest is not a heavy server, but it punishes weak single-core performance and slow storage. Get a machine with a modern high-clock CPU and an SSD, set the config once, automate the restarts and backups, and the server will outlive most communities’ attention spans. Budget roughly 10 GB of RAM for a full eight-player world, keep a second drive for save backups, and treat every game update as a scheduled maintenance event rather than an emergency.
