The AASM desktop app is the primary control surface, but v0.8.3 ships an optional Web UI served by an embedded Express server. Once enabled, you can manage your fleet from a phone, tablet, or any browser on your LAN - useful for checking on servers without RDPing into the host PC.

Prerequisites:

AASM admin role - viewer/dashboard/operator can't toggle the Web UI server.
A free TCP port on the host PC (default 3000).

Step 1 - Open the App Settings dialog

Click the gear icon (⚙️) at the top right of the AASM window. The App Settings dialog opens.

Step 2 - Switch to the Web UI section

Find the Web UI section (sometimes labelled Web Server depending on your version). Three controls live here:

Enable Web UI - master on/off switch.
Port - TCP port the embedded Express server listens on. Default 3000.
Bind Interface - which network interface to listen on. 127.0.0.1 = localhost only, 0.0.0.0 = every interface (LAN + WAN if your firewall allows).

Step 3 - Flip Enable on

Click Enable Web UI. AASM boots the Express server. If the port is already in use, you'll get a snackbar - pick a different port.

Step 4 - Open the Web UI from another device

Find the AASM host PC's LAN IP (e.g. 192.168.1.42). On another device on the same LAN, open:

http://192.168.1.42:3000

Log in with the default credentials shown in the App Settings → Web UI section. Change them immediately afterwards via Web UI Roles & Permissions.

Don't expose port 3000 to the internet without HTTPS. By default the Web UI runs HTTP only. See Installing HTTPS Certificates if you need WAN access.

Step 5 - Set the AASM host PC's firewall

For LAN-only access, you may need to open the Web UI's port on Windows Firewall (a different operation from the per-server Open Firewall Ports flow - that one's for game ports, this is for the Express server's TCP port). Use wf.msc or the AASM Web UI port-opener if your version exposes one.
