The direct answer first: neither Grounded nor Grounded 2 has an official dedicated server. Obsidian shipped the original game with peer-to-peer co-op plus a Shared World system, and Grounded 2 entered Early Access in July 2025 the same way — 4-player co-op, no server binaries, and no confirmed plan for them. Everything called a "Grounded dedicated server" in 2026, including the ones game-server companies rent out, is built on a community framework called Lantern. The good news: you can run that framework yourself on any small server, and this guide covers all three real options.
Option 1: Shared Worlds — the official way
Grounded's Shared World feature lets a world live semi-independently of its creator: up to eight named players are authorized, and any of them can host a session in that world even when the original creator is offline. The world state syncs through the platform's save system. For most groups of friends this is genuinely enough, and it costs nothing.
The limits are structural, not bugs: someone's game client must be running to host, the hoster's upstream connection and PC carry the session, progress pauses when nobody hosts, and player count stays capped at 4 simultaneous. If your group spans time zones and wants the world "always on", Shared Worlds cannot deliver that — which is exactly the gap the community filled.
Option 2: Lantern — the community dedicated server
Lantern is a third-party framework that swaps Grounded's stock lobby/matchmaking transport for standard Unreal Engine networking. The result behaves like a classic dedicated server: a headless process runs 24/7 on a machine you control, keeps the world loaded, saves on schedule, and players connect directly by IP and port through the Lantern launcher. Admin features (passwords, RCON-style control, save backups) come with the panel tooling around it.
Two honest caveats before you commit an evening to it:
- It is unofficial. A game patch can break compatibility until the framework updates. Keep automatic game updates off on the server and update deliberately.
- Everyone needs the launcher. Each player joins through Lantern, not the in-game menu — a one-time setup step per friend, but a real onboarding cost.
Worth knowing: the commercial "Grounded server hosting" offers from game-server providers run this same framework under a rental panel. Renting is convenient; it is also $10–15/mo for a slice of hardware you could own outright.
Self-hosting Lantern: sizing and setup logic
A 4-player Unreal survival world is a light load by server standards. From instances we have seen run:
- CPU: 2 modern cores are sufficient; 4 give headroom for world events. Per-core clock speed matters more than count, as with most Unreal servers.
- RAM: 6–8 GB covers the server process comfortably.
- Disk: the install plus saves fits in 30 GB; any SSD is fine.
- Network: a handful of players uses a few Mbps — location (ping) matters far more than bandwidth.
That spec is entry-level everywhere: a small VPS carries it, and on the dedicated side the $25–35/mo tier in our catalog runs Grounded alongside two or three other game servers — the same consolidation logic covered in our game hosting hardware guide. Pick the city by where your group lives: Chicago for North America, Frankfurt or Warsaw for Europe, Singapore or Sydney for APAC. Open the UDP port Lantern is configured to use, run the process as a non-root user, and schedule save backups off-machine.

Which option fits which group
| Shared Worlds | Lantern self-host | Lantern rental | |
|---|---|---|---|
| Cost | free | server rent ($10–35/mo, shared with other uses) | $10–15/mo |
| Always online | no — a player must host | yes | yes |
| Survives game patches | always | after framework updates | after framework updates |
| Setup effort | none | an evening once | minutes |
| Control (mods, saves, access) | minimal | full | panel-limited |
Practical recommendation: start with Shared Worlds — it is official and free. Move to Lantern the day your group genuinely feels the "host must be online" limit, and self-host if you already rent any server; the marginal cost of adding Grounded to an existing box is zero. Status of facts: checked July 6, 2026 — if Obsidian ships official server binaries for Grounded 2 later in Early Access, this article will be updated.
