WatchYourLAN on Ubuntu 24.04
Azure
Networking
WatchYourLAN, a lightweight network scanner with a web dashboard that shows every host on your network, ready the moment it boots.
Overview
WatchYourLAN is a lightweight, self-hosted network scanner with a modern web dashboard. It periodically scans your local network, discovers every device it can see, and records each host's MAC address, IP address, name and vendor along with a full online and offline history, so you always know what is connected. New or unknown devices are surfaced immediately, and every host is queryable through a clean web UI and a REST API.
It suits home-lab owners, network administrators and small teams who want continuous visibility of the devices on their network, a running record of when hosts appear and disappear, and early warning of unexpected arrivals, all from a single self-hosted dashboard they fully own and control.
Why the cloudimg image
cloudimg delivers WatchYourLAN fully installed and configured, with the scanner and its SQLite datastore already running behind an nginx reverse proxy, so a working network dashboard answers the moment the instance boots. Because WatchYourLAN has no built-in login of its own, the image is secure by default: the application binds only to the local loopback interface and is never exposed directly, and on the first boot of every instance a unique administrator password is generated and written to a file only the root user can read, then enforced by nginx HTTP Basic Auth, so no two deployments ever share a login. The image is hardened, fully patched and pinned to a known release, and every deployment is paired with a step by step deploy guide and backed by 24/7 support.
Common uses
