# Hosting a Necesse server: the complete guide

Necesse is played together on a world that keeps living: you settle in, recruit villagers, head out on expeditions. As long as one player hosts the game, everything stops when they close it. A dedicated server keeps it standing between sessions — and here, it is only billed for the hours it runs.

## 1. Create the server

Pick **Necesse**, the RAM and the performance level. The server starts on its own; you get a stable connection address and a password to share.

There is **nothing to lock in at creation**: unlike other games in our catalogue, Necesse does not force you to pick a world mode or a final difficulty at the moment you open the server.

## 2. A very fast start

The game is baked into the image we serve: nothing to download at start-up. On our test bench the server was **ready in seven seconds** and used about **800 MiB of memory** at rest. The very first start adds world generation; later ones simply load what already exists.

## 3. Joining the game

In the game, join a server with the **address and port shown in your console**, then enter the password.

You have **no ports to open**: the game port (14159) is already in place.

The server takes **8 players by default, up to 20**.

⚠️ **Necesse refuses a client whose version differs from the server's.** That is a constraint of the game, not a hosting policy: a server left on an old version becomes unreachable for everyone the day the game updates. Our servers follow the published version of the game — a restarted server comes back on the current one, with nothing for you to do.

## 4. The console, and who commands the server

Necesse is one of the games in our catalogue with a **console in your account**: you see connected players by name, and you can **kick** or **ban** in one click while the game runs.

A word about permissions, because the game's behaviour is surprising: Necesse grants owner rights to the client that connects **with no name**. Left as is, anyone could take over the server. We fill that field with a secret drawn at random **for every session**: the seat is taken, and moderation happens from your console rather than through an in-game command.

## 5. The welcome message

It is the only piece of text to set, and you can change it whenever you like: it is shown to players as they join. Left empty, nobody sees anything.

## 6. Your world is kept between sessions

Necesse saves **on its own, about every minute**, and keeps a backup copy of the previous save — the shortest worst-case loss in our catalogue if something cuts out. On shutdown the server gets its quit command, saves one last time, then exits; the world is archived and restored on the next start, on a brand-new machine.

Already have a world running? Bring it over:

1. Grab your world's `.zip` file, from Necesse's `saves` folder.
2. Put it **at the root of the archive**, with no folder around it.
3. Upload the archive when you create the server. We put it in the right place under the right name, so the server loads your world instead of generating a new one.

## 7. How much RAM?

Necesse runs on Java, and that is what makes sizing simple here: **there is no heap to set**. The Java virtual machine automatically takes 70% of the VM's memory, so the tier you pick IS the server's memory — not a number to copy into a field, nor a ceiling that would starve everything else.

| Your game                     | What we recommend |
| ----------------------------- | ----------------- |
| Up to 8 players, with friends | 4 GB              |
| Up to 20 players, community   | 8 GB              |

Those two rows come from a dated survey: our own measurement for the floor (about 800 MiB idle, well below the first tier) and a specialist host's tiers for the progression. The price follows the RAM and the performance level, **never the game**.

## 8. Mods

**Our Necesse servers are vanilla.** There is no mod upload in your account: the server follows the published version of the game, and a mod tied to one precise version would break on the first restart after an update — silently, and at the worst possible moment.

## 9. Shut it down when you are done

Server off = €0. Auto-shutdown kicks in on its own once nobody is connected, and the world comes back untouched next time. On a game you pick up in waves, that is where the gap with a monthly plan opens up.
