7 Days to Die Dedicated Server Hosting 2026: Setup and Best Practices
7 Days to Die — or 7DTD — is the original zombie survival builders' game. With its random world generation, blood moon horde nights, and deep crafting systems, it creates some of the most memorable co-op gaming moments available. Version 1.0 was a massive overhaul that brought the game to full release status, and in 2026 it remains one of the most popular survival multiplayer games to self-host.
Why 7DTD Servers Need Good Hardware
Blood moon horde nights — which happen every 7 in-game days — spawn hundreds of zombies simultaneously attacking your base. During these events, the server simulation spikes dramatically. A server that handles normal gameplay fine can visibly struggle during horde nights if it is underpowered.
Additionally, procedural world generation at server startup is memory-intensive. A 10K map takes several minutes to generate and uses significant RAM.
Hardware Requirements for 7DTD 2026
| Setup | RAM | Notes | |---|---|---| | Small (1-8 players, vanilla) | 6-8 GB | Standard 8K world | | Medium (8-16 players) | 8-12 GB | Standard 10K world with mods | | Overhaul mods (Darkness Falls, etc.) | 12-16 GB | Significantly higher requirements |
Overhaul mod packs like Darkness Falls, Ravenhearst, and Undead Legacy dramatically increase requirements because they add hundreds of new items, recipes, and zombie types.

# Run the server
cd /opt/7dtd_server
./startserver.sh -configfile=serverconfig.xml
Key Settings in serverconfig.xml
<property name="GameName" value="My World"/>
<property name="GameMode" value="GameModeSurvival"/>
<property name="WorldGenSeed" value="asdf1234"/>
<property name="WorldGenSize" value="8192"/>
<property name="ServerMaxPlayerCount" value="8"/>
<property name="BedrollDeadZoneSize" value="15"/>
<property name="BloodMoonEnemyCount" value="8"/>
<property name="DayNightLength" value="60"/>
BloodMoonEnemyCount — reduce this to 6-8 on lower-powered servers. The default is tuned for local play with good hardware.
DayNightLength — 60 minutes = 1 real minute per in-game hour. Adjust based on how fast you want days to pass.
Managing the Game World
7DTD worlds can grow large as players explore chunks. The map is technically infinite in the vanilla game (it wraps), but players generally explore a limited area. Monitor your server's memory usage over time — a busy server after 30 days of play may use notably more RAM than at launch.
Mods: Overhaul vs. Small Additions
The 7DTD modding community is exceptional. The decision point is whether to run a full overhaul mod (Darkness Falls, Ravenhearst) or smaller individual mods (custom zombies, UI improvements, weapon packs).
Full overhauls fundamentally change the game and usually require all players to use the same modded client. They are worth the extra hardware cost for established communities that want a fresh experience.
Hosting 7DTD at Space-Node
Horde nights are the real test for any 7DTD server. Our Ryzen 7 9700X hardware handles the spike in zombie simulation during blood moon events without the frame-rate-style stuttering you get on weaker hardware. NVMe storage ensures world chunk loading during active exploration stays fast.
