Game Hangout · SCUM
The official dedicated server on a friend's PC, one click, and nobody pays for a slot.
Free. No account. Server files: 16.5 GB, once, on the host's PC.

Says what the server will make of it: the level it asks for and where that is set up, the arguments, and the nearest real name when the spelling is off. For #SpawnItem it knows the item names too, and why one refuses.
The server itself: the 16.5 GB download, once, on the host's PC; the three ports SCUM needs, set right; the tunnel to your friends instead of port forwarding; and the world that follows whoever starts it next.
The settings that matter are on a screen: name, password, PVE or PVP, admin rights, elevated users. The rest of ServerSettings.ini is there too, raw. Change something, restart, done.
What to put in AdminUsers.ini and in the database before a command works, then the commands by task — money, skills, spawning past 10, the item list — each one typed on SCUM 1.3.3 by us, and all 233 commands the server knows, read from its own files.
6 GB to download but 17 GB on disk, three UDP ports, a query port you have to spell out and a log line that lies. Setting up a SCUM dedicated server on your own PC, measured on a real install.
All 3,292 item names a SCUM 1.3.3 server will spawn, read from the server's own files and sorted the way the game sorts them — with the #SpawnItem line ready to copy.
Yes: 16.5 GB, from Steam's manifest. Only the hosting PC needs them, once. Everybody else needs the game and the app.
SCUM servers are usually reached over an IP and a forwarded port. Game Hangout skips that: the server answers on an address inside the tunnel, and your friends join from the app.
That is the trade with any friend-hosted server, and the app is honest about it on the homepage. What it does about it: the world follows whoever starts next, so nobody's evening is lost — and an always-on PC of your own can hold it overnight.
Every release is signed, and the app keeps itself up to date from then on.
