Which Rimworld: Open World Plan Is Right for You?
Compare recommended use, plan hardware and monthly prices.
| Plan | Recommended for | Hardware | Monthly price |
|---|---|---|---|
| Bronze 4GB | 2–20 players, most communitiesThe server does not run RimWorld; this plan is generous for a typical Open World server. | 4 vCore Ryzen 9950X · 4 GB DDR5 6000MHz · 50 GB NVMe SSD Samsung 990 PRO | ₺240.00/mo |
| Silver 6GB | 20–40 playersHeadroom for bigger groups and player data that has piled up over months. | 4 vCore Ryzen 9950X · 6 GB DDR5 6000MHz · 60 GB NVMe SSD Samsung 990 PRO | ₺345.00/mo |
| Gold 8GB | Large community; overkill for mostMemory needs stay low; this tier only makes sense on very crowded worlds. | 4 vCore Ryzen 9950X · 8 GB DDR5 6000MHz · 70 GB NVMe SSD Samsung 990 PRO | ₺440.00/mo |
| Platinum 10GB | Bigger than Open World needsThe extra RAM goes unused; the added disk only helps with a long backup archive. | 4 vCore Ryzen 9950X · 10 GB DDR5 6000MHz · 100 GB NVMe SSD Samsung 990 PRO | ₺530.00/mo |
| Diamond 12GB | Not recommended; far above needSame 4 vCores; you will not feel a difference from Bronze on an Open World server. | 4 vCore Ryzen 9950X · 12 GB DDR5 6000MHz · 110 GB NVMe SSD Samsung 990 PRO | ₺617.50/mo |
| Emerald 16GB | Unnecessary for Open World6 vCores and 16 GB mostly sit idle on this light, data-only server. | 6 vCore Ryzen 9950X · 16 GB DDR5 6000MHz · 120 GB NVMe SSD Samsung 990 PRO | ₺840.00/mo |

Why TheCrewHost for Rimworld: Open World?
The tools an Open World server actually uses, and nothing it does not.
Lightweight .NET Server
The Open World server does not run RimWorld itself; it is a .NET application that stores and relays data between players, which is why even the smallest plan is comfortable.
Three-Folder Mod Control
Mods in Enforced Mods are mandatory, mods in Whitelisted Mods are allowed and mods in Blacklisted Mods are banned; set the rules up through the file manager or SFTP.
Server Rules in Config.json
Set the player cap, whitelist, forced difficulty and custom scenario permission in the server's config files, then restart to apply them.
Whitelist for Closed Groups
With the whitelist enabled, only usernames on the list can join. It is the quickest way to keep strangers from settling on your group's planet.
Player Data Backups
The server keeps player and world data in its own folders. Automatic panel backups cover those folders, and you can take a manual backup before any big change.
24/7 Support
Version mismatches, players locked out by enforced mods or a server that will not start: reach us by ticket, Discord, WhatsApp, phone or live chat.
You can host a shared RimWorld Open World planet at TheCrewHost from $6.00 (₺240.00) a month; each of the 7 plans, spanning 4 GB to 32 GB, runs on a Ryzen 9 9950X with NVMe storage. Open World is a free mod that adds asynchronous multiplayer to RimWorld: every player runs their own colony on their own PC, while the server holds the shared planet, player accounts, and the trading, gifting and PvP between them. The server is a lightweight .NET program, and its config files and mod folders decide who can join with which mods. Hosting in İstanbul keeps interactions snappy for players in Türkiye.
What is Open World, and how is it different from co-op?
Open World is a free multiplayer mod for RimWorld, and it does not work like classic co-op. Players do not manage one colony together; each runs their own colony on their own computer at their own pace. What they share is the planet: other players' settlements appear on the world map, and players can trade, send gifts, barter and clash in PvP.
This asynchronous design has two big consequences. First, nobody has to be online at the same time; one player can play late at night while another picks up the next morning and finds the gift a neighbor left. Second, because colony simulation runs on each player's PC, the server itself is very light.
If you want to run the same colony together in real time, Open World is the wrong tool; other co-op mods, hosted from one player's own game, cover that. Open World is for groups who want a persistent world where everyone writes their own story but still trades with, and occasionally fights, the colonies next door.
Open World or Rimworld Together?
Both mods share the same idea: everyone plays their own colony, and the planet is shared. They differ in development status and feature set. The last server release of Open World published on GitHub is v1.0.4, and its server runs on .NET Core 3.1. Rimworld Together is the newer project, with its own wiki, detailed configuration files and extra features such as sending events to other players and building roads.
Pick Open World when your group already plays on an Open World planet, when your players are set up around a specific version of this mod, or when you prefer the leaner feature set of trading, gifts and PvP. The server only accepts players connecting with the mod version it is set to, so everyone must run the same one.
If you are starting a brand-new community, look at our Rimworld Together page first. And before installing Open World, confirm on the mod page that it works with the RimWorld version your players run; that check is far less painful than trying to move a world to another mod a few weeks in.
How much RAM does an Open World server need?
Very little. The Open World server never runs RimWorld itself; it stores player accounts, settlement details and interaction data. The colony simulation, meaning pawn AI, raids and weather, is calculated on each player's own computer. That puts our Bronze 4GB plan well above what a typical Open World server needs.
What grows with player count is disk use and connection traffic more than memory. Every player's data accumulates on the server, and backups take up space over time. Fast NVMe storage keeps that growing pile of files quick to access.
How many mods your players run in RimWorld does not change the plan choice either, because that load lands on their machines, not on the server. Our honest advice: unless you are building a public world for hundreds of people, you do not need anything above Bronze. The only real advantage of bigger plans here is extra disk space for backups you want to keep for a long time.
Managing mods, the whitelist and server settings
On its first run, the Open World server creates the files and folders it needs. Settings center on Config.json, Deep Config.json and Values.json, and it is best to edit them before anyone connects. Edit them only with the server stopped, and restart it once you are done.
Mod management runs through three folders. Mods placed in Enforced Mods are required for every player; mods in Whitelisted Mods may be used optionally; connecting with anything in Blacklisted Mods is forbidden. Settle your enforced mods before the planet is created, because adding a required mod to an established world can cause problems in players' existing colonies.
With the whitelist on, only usernames listed in the Whitelist file may join. When custom difficulty is enabled, everyone plays with the settings in the Difficulty file, which keeps competition fair on a planet with PvP. The custom scenario option controls whether players may use their own scenarios when creating a save. Later releases also added chat commands, a server password and a shutdown routine that preserves data.
How do players connect to an Open World server?
Every player needs the Open World mod installed in RimWorld at the version your server accepts. Once it is loaded, they open the mod's connection screen and enter the server's IP address and port. Open World's default port is 25555; if your panel assigns a different one, use that.
The first person to connect creates the server world by following the in-game prompts, and later players pick their spot on that planet. It makes sense for the server owner to log in first and choose the world settings deliberately.
If a required mod is missing, or a player shows up with a banned one, the connection is refused. Sending the mod list and mod version to players ahead of time, by message or in a Discord channel, keeps the first evening from turning into a round of connection troubleshooting. With the server in İstanbul, trade offers and gifts between players in Türkiye arrive without delay.
How to Set Up a Rimworld: Open World Server
- 1
Start with Bronze 4GB
The Open World server is light; colony simulation happens on players' PCs, so Bronze 4GB is more than enough for small and mid-sized groups.
- 2
Let automatic setup finish
After payment the server installs and creates its files and folders on first run; reach all of them at gamepanel.hostingmerkezi.net.
- 3
Edit the config files
Stop the server and set the player cap, whitelist and game rules in Config.json, Deep Config.json and Values.json.
- 4
Fill the mod folders
Upload required mods to Enforced Mods, allowed ones to Whitelisted Mods and banned ones to Blacklisted Mods using the file manager or SFTP.
- 5
Log in first and create the world
Start the server, connect with the IP and port from the mod's connection screen, and as the first player follow the prompts to create the shared planet.
- 6
Send your players the mod list
Share the mod version, the required mod list, the IP and the port; once everyone connects on the same version, the planet starts filling up.
