Nitrox synchronizes every player's built pieces, vehicles and picked-up resources through the host, so a long expedition grows the world file steadily and rewards unmetered NVMe storage plus generous memory.
Your Nitrox server is provisioned automatically after checkout, so the crew can be swimming out of Lifepod 5 the same evening.
Automated setup · Live console
Reach the Nitrox world directory and configuration through the file manager or SFTP to adjust the server name, password and save folder.

DDoS protection is active on every server at no extra cost, which keeps a shared dive from ending with everyone disconnected at once.

Subnautica shipped as a single-player game and has no official multiplayer mode. The only way to explore 4546B with friends is Nitrox, a community-built modification that adds a server component and syncs players, vehicles, base pieces and resource state. Hosting that server component here means the world stays available without anyone running it from a home machine, and 9 locations let you place it near the crew.
Nitrox is installed on both sides: each player patches their own Subnautica copy, and the matching server build runs on the host. The FSH panel keeps that manageable with a file manager for dropping in server files, SFTP for bulk transfers, a live console for reading startup output, and automatic daily backups with 10 rolling slots. Because a Subnautica game patch can break a Nitrox build, take a backup before updating anything and keep every player's mod version identical.
A Subnautica playthrough is a slow build of scanned fragments, blueprint unlocks and a base you keep extending, and losing that hurts more than losing gear in a shooter. Rolling daily backups plus manual restore points before risky changes cover the common failure modes, and the published SLA at /legal/sla sets a 99.9% monthly uptime target. The task scheduler can also restart the server nightly to keep memory use tidy.

Common questions about running a Subnautica server with us.
No. The base game is single-player only, and every multiplayer option comes from Nitrox, an unofficial community mod that adds a dedicated server and client patch. We host that server for you on enterprise Ryzen 9 hardware, but the mod itself is maintained by its own community, so feature gaps and rough edges are expected.
Two players on a young world are fine on the 2 GB plan at $5.00 a month. Memory demand rises with how much you have built and how many entities the world tracks, so groups of four to six usually settle on 6 GB. RAM costs a flat $2.50 per gigabyte, and upgrades keep your existing world.
Nitrox stores its world in its own format rather than reading a vanilla save, so importing a single-player playthrough is not something the mod supports. Plan on a fresh start for the group. Your solo save stays untouched on your own machine, and the server's daily backups protect the new shared world once you begin.
Yes. Client and server builds must match, and a Subnautica update can require a new Nitrox release before anyone can connect. The panel's file access and 10 rolling backup slots make the update cycle low risk: snapshot the world, replace the server files, then restart from the live console and check the output.
We never cap or sell player slots, so the practical ceiling is what Nitrox handles gracefully rather than a billing limit. Small crews of two to six are the common case and run well. Larger groups put more simultaneous entity syncing on the host, so step up to 6 GB or 8 GB if you plan to fill the ocean.
