About NetAlertX

NetAlertX is a platform for network visibility and asset intelligence, built for people running homelabs, IT departments, managed service providers and distributed setups. It keeps discovering devices on segmented networks, VLANs, branch offices and other remote sites and presents them in one interface, giving a live view of what is connected.

That inventory helps spot shadow IT, unauthorized hardware and IPAM drift, supports compliance work and lets service teams react to changes that matter. Multi-site sync, reporting, workflows and webhooks automate follow-up, which the project presents as a way to get ahead of issues while avoiding the weight of a complete network management system or SIEM. Topics mention ARP scanning, network monitoring, asset management and DCIM.

NetAlertX is written in Python and licensed under GPL-3.0. The recommended way to run it is with Docker, using a data directory that holds the config and database folders, and the README warns that the docker-compose file changed recently and a migration guide should be read first. It suits homelab owners and managed service providers who want lightweight device tracking.
