Memory Machine runs a web server on port 8080. The mmlet.service and mmmgr.service are enabled and started by the installer and should automatically start at boot time. To verify the systemd service status, run:

$ sudo systemctl status mmlet mmmgr

For example:

$ sudo systemctl status mmlet mmmgr
