Sons of the Forest is demanding: even without players the server uses about 7 GB on our test servers. That's why our servers start at 8 GB.

Guide values

Players at onceRecommendation
up to 48–10 GB
5–810–12 GB
8 with large bases12–16 GB

Sons of the Forest allows at most 8 players at once.

What else affects the requirement

  • Bases: Large buildings with many logs and traps cost more over time.
  • Spread-out players: If players roam the whole island, the server has to simulate more areas at once.

Start small, upgrade later

You don't have to decide right away: you can change the memory yourself at any time – your world, mods and settings stay, and on an upgrade you only pay the pro-rata difference. See Booking more or less memory.

On the server page, the history shows how much memory your server really uses and recommends a suitable tier if needed – more on this. If it lags even though memory is free, more CPU power usually helps more.
