Portal Knights Server Hosting
Hop between islands, fight bosses and build together while the AI copilot keeps the world open.
What do you need for Portal Knights server hosting?
Portal Knights server hosting needs very little: 2–4 GB of RAM, the dedicated server that ships inside the game as dedicated_server.zip, UDP port 16365 reachable, and a server_config.json with your passwords. The game allows 4 players per world. Or rent a Portal Knights server that is ready to go. On GameTeam you pay per GB of RAM, from $0.49/GB a week, so 2 GB is $0.98 a week, and the AI copilot sets passwords, uploads your world and makes backups when you ask.
Run your Portal Knights server by just asking.
A Portal Knights server is one JSON file with three password groups, and one missing comma is enough to break it. Tell the copilot who should get in and what they may do: it writes the file, moves your world in, and backs it up, since the server never touches Steam Cloud.
Home Island, Always There
The world persists at a fixed address between sessions.
One of the Cheapest to Run
Very little RAM needed — a plan that costs less than a coffee a week.
Same Server, Next Game
When the islands are explored, switch the server to whatever comes next.
Portal Knights with friends
A bright action RPG in a world of floating islands: mine, craft, build, and fight through dungeons and bosses as a warrior, mage or ranger. It is friendly and cooperative by design — a small group can build a home island and adventure out from it.
Portal Knights server RAM requirements
2-4 GB. It is one of the lighter dedicated servers we host.
| Your server | Starting RAM | From (Budget, weekly) |
|---|---|---|
| Up to 4 players, Small or Normal universe | 2 GB | $0.98 / week |
| Up to 4 players, Large universe and a big castle | 4 GB | $1.96 / week |
Portal Knights is one of the lightest servers we host, because a world holds 4 players at most. These are starting points: a Large universe and a heavily built home island are where the extra gigabyte or two goes. Change RAM in one click from the panel; the world stays as it is. Player limit: 4 per island session.
How to set up a Portal Knights server on GameTeam
Pick 2 GB and a location
2 GB is plenty for most groups. Choose the location closest to your friends from 25+ across Europe, the Americas and Asia-Pacific.
Set passwords and the universe
Give the admin and user groups their passwords and pick a universe size in server_config.json, or tell the copilot. Have a world already? Upload it from your Steam save folder.
Add the server in game
In Portal Knights, go to Join, then Servers, then Add Server. Enter the IP and port from the panel and the password for your group.
Good to know before you start
The island world is created at first start from the configured settings.
Portal Knights server settings explained
The server writes server_config.json on first start. Edit it with the server stopped and keep every entry in plain ASCII or UTF-8, as the developer warns. These are the keys in the file:
| Setting | What it does |
|---|---|
basicServerData.name | The server name players see. |
basicServerData.port | The game port, 16365 by default. |
basicServerData.ipv4 | The address to listen on. The default 0.0.0.0 means all of them; you rarely need to change it. |
basicServerData.saveFolderPath | Where the world is saved, ./savedata by default. |
universeSize | Small, Normal or Large. |
hideConsoleWindow | Hides the console window. Only useful on your own PC: you then have to close the server from Task Manager. |
admins / users / guests | The three groups. Each has its own password and rights. Keep the admin password to yourself. |
credentials.password | The password for that group. Share the user password with friends. |
canLogin | Whether the group can join at all. Guests cannot by default. |
canKickPlayers | Whether the group can kick players. Only admins can by default. |
canModifyWorld | Whether the group can mine and build. |
canInteractWithLockables | In the file, but the developer lists it as not working yet. |
Portal Knights server commands
The developer's guide lists no console commands for the server: you manage players through the group permissions above, and any group with canKickPlayers can kick. The server executable takes two start options, meant for running more than one server on the same PC:
| Command | What it does |
|---|---|
-config <file> | Loads a different config file, and creates a default one if it does not exist. |
-log <file> | Writes the log to a file you choose. |
Can I add mods to a Portal Knights server?
Portal Knights has no official dedicated-server mod support.
The Steam Workshop for Portal Knights is for sharing Creative Mode builds, not server mods. What you can change on the server is what server_config.json exposes: name, universe size and who may join, build and kick.
Portal Knights server ports
At home you would forward UDP 16365 to your PC and hand out your external IPv4 address. On GameTeam there is nothing to forward: the panel shows the exact address and port, which may differ from the default.

What server owners say
"Honestly didn't expect much from an 'AI manager', but it's how I run my server now. I'll type something like 'why did the server crash last night' and it actually reads the logs and tells me."
Verified review
"I'd been on two other hosts before this. What sold me was the AI manager catching a memory leak in one of my mods and naming the exact one — something I'd been chasing for weeks."
Verified review
"I'm not very technical and setting up servers always stressed me out. Now I just ask the assistant to fix a config, and it either walks me through it or does it for me."

Portal Knights server hosting FAQ
How much does Portal Knights server hosting cost?
You pay per GB of RAM: $0.49/GB a week on Budget, or $1.99/GB billed monthly. 2 GB is $0.98 a week and 4 GB is $1.96 a week, with the AI copilot included on every plan.
How many players can join a Portal Knights server?
Four per world. That limit comes from Portal Knights itself, which is built for 4-player co-op, not from us; GameTeam never sells slots. A dedicated server's real advantage is that those four don't all have to be online at once, because the world stays up without its host.
How do I join a Portal Knights dedicated server?
Choose Join, then Servers, then Add Server, and enter the server's IP and port from your GameTeam panel. Use the password of the group you belong to. There are no public servers or matchmaking, so the address has to be shared directly.
Can I move my single-player world to the server?
Yes. Your worlds sit in Steam\userdata\<your Steam ID>\374040\remote. Upload those files and they go into the server's savedata folder. Only the world moves: each player keeps their own character, which lives on their own PC.
Why does my Portal Knights server not start after I edited the config?
Check first whether server_config.json is still valid JSON: a missing comma or quote, or a character the file can't read. Keep entries in ASCII or UTF-8. On GameTeam the copilot checks the file and repairs it without losing your values.
Does a Portal Knights server back itself up to Steam Cloud?
No. The dedicated server is not connected to Steam Cloud, so the developer recommends regular backups of the save folder. On GameTeam, back up from the panel or ask the copilot to make one before you try something risky.
What is the difference between the admin, user and guest passwords?
Each group has its own password and rights. In the default file only admins can kick, users join with their own password, and guests cannot join at all until you turn on canLogin. A guest group that can join but not build is a good way to show visitors your castle.
How do I update my Portal Knights server?
Stop it and start it again from the GameTeam panel and it updates to the latest version. Players must run the same game version as the server, so if someone cannot connect, check they are fully updated.
Same server, any game.
Your home island, open whenever a friend logs in.
Deploy a small server, tell the copilot who gets which password, and send your party the address.
