NetMap answers the four questions every homelab owner asks in four different tools: what is on my network, what address did it get, is it still up, and why is the firewall shouting about it. Devices you add appear automatically on a visual canvas where you can drag them into place, draw the links between them, and group them into VLANs or separate sites, and the layout is still there when you come back. Behind the map, every device is watched continuously: ping times graphed over history, service checks on the ports you care about, a heartbeat strip that betrays intermittent dropouts, and an uptime percentage that settles arguments. Address management stops being a spreadsheet: define subnets, import the leases your router already handed out, see used and free addresses as a grid, and get warned before a duplicate assignment causes a mysterious outage. Firewall logs stream in live and each entry links to the device it concerns, ready to search by address, port, or protocol. When something new appears, a network scan discovers hosts with their names, hardware addresses, and open ports for review before they join the inventory.
