WebPublish runs a single HTTP server that handles every publishing task. Two settings control where that server listens: the port and the address (IP binding). Both can be changed in Settings → Basic.

​
Port

SettingConfig keyDefault
Portport9090
The port determines the TCP port number the server binds to. All task URLs include this port: 
http://{address}:{port}/{taskId}/...
For example, with the default settings a directory task with the ID my-site is accessible at: 
http://127.0.0.1:9090/my-site/
Changing the port updates every task URL immediately after the server restarts.
Port numbers below 1024 are reserved on most operating systems and require elevated privileges. Use a port in the range 1024–65535.

​
Port conflicts

If the selected port is already in use by another process, WebPublish fails to start the server and displays an error. To resolve this:
  1. Stop the process currently occupying the port, or
  2. Change the WebPublish port to a free port number in Settings → Basic.

​
Address

SettingConfig keyDefault
Addressaddress127.0.0.1
The address controls which network interface the server binds to.
ValueEffect
127.0.0.1Localhost only. Only the machine running WebPublish can access the server.
LAN IP (e.g. 192.168.1.10)Accessible to other devices on the same local network.
0.0.0.0Binds to all interfaces. Accessible from any network interface, including public ones.
Binding to 0.0.0.0 or a public IP address exposes all of your publishing tasks to every network the machine is connected to. Anyone who can reach that IP and port can access your files. Only do this on networks you trust, and ensure your firewall is configured appropriately.

​
Allow LAN access

To share content with other devices on your local network:
1

Find your LAN IP address

On Windows, run ipconfig in a command prompt and look for the IPv4 Address under your network adapter. On Linux, run ip addr and look for inet on your active interface.
2

Open WebPublish settings

Click the gear icon in the toolbar, or right-click the system-tray icon and choose Settings.
3

Update the address

In Settings → Basic, replace 127.0.0.1 in the Address field with your machine’s LAN IP address (for example, 192.168.1.10).
4

Restart the server

Click OK to save. WebPublish restarts the HTTP server and all task URLs update to reflect the new address.
5

Verify access from another device

On another device on the same network, open a browser and navigate to a task URL, for example:
http://192.168.1.10:9090/my-site/

​
How task URLs are constructed

Every task URL follows this pattern: 
http://{address}:{port}/{taskId}/...
  • {address} — the configured IP binding
  • {port} — the configured port number
  • {taskId} — the unique ID you assigned when creating the task
All tasks share the same server, port, and address. Tasks are differentiated only by their ID prefix in the URL path.
Choose task IDs that are short, lowercase, and URL-safe (letters, numbers, and hyphens). Avoid spaces or special characters.
