Neos is capable as running as a websocket client in game by utilizing the WebsocketClient component and the Websocket LogiX nodes. This can lead to a powerful opportunity to connect Neos to other applications.

Basic Information

Check the information on these nodes and components for basic information about how to use them:


For websockets to work you'll need to ensure:

  • A websocket compatible server
    • Not a regular Socket Server
    • Not a Socket.Io Server
    • Not any other kind of server. Specifically Websockets
  • A computer to run your Websocket Server.
    • This can be the same computer as the one that runs Neos.
  • Some knowledge of how to program a websocket server.
    • Most websocket servers are basic and do not include your application logic.

Neos Limitations

  • Neos can only send and receive text based messages.
    • Do not send Binary data!


If websockets are not working in your world please check the following:

  • Is your address correct?
    • It must be an address that Neos and your computer can reach.
    • Localhost or are ok if you're referring to your local computer.
  • Is the port correct?
    • You can run a Websocket server on any port.
  • Does your address start with ws:// or wss://?
    • It must NOT start with http:// or https://
  • Is your websocket server running?
    • It must be running to connect successfully.
  • Is the "User" property set to the person running the websocket server?
    • Websocket connections run as a specified user. If this is incorrect they might not connect correctly.
  • Have you denied the webhost in Neos?
    • Navigate to the home screen of your dash.
    • In the bottom right corner click on Debug.
    • Then in the window that appears click the "Web Hosts" tab.
    • Check for any line in the window that shows the address that you're trying to use.
    • If it says "Denied" click "Remove Setting" next to it and make sure to "Allow" it when the request access dialog appears.
