Most network scanners answer "Unknown device". Network Toolkit doesn't. It sweeps your subnet in seconds and, for every device, shows what it thinks it is — with a confidence score and the evidence: mDNS services, SNMP descriptors, open ports, the web server's title. Also: ping, port scanner, DNS lookup, Wake-on-LAN, Wi-Fi channel analysis, offline alerts. No account. No cloud. Free with ads; optional one-time PRO, no subscription.
I built this because the app everyone recommends for "who's on my Wi-Fi" wants you to create an account before it will scan your own LAN.
The part I care most about is device identification. "Unknown device" is a useless answer, so the app shows its reasoning — which mDNS services the device advertises, what its SNMP descriptor says, which ports are open, what its web UI is titled — and gives you a confidence percentage.
It's free and ad-supported. Built with .NET MAUI, entirely on managed sockets: shelling out to ping and calling InetAddress.isReachable() both destabilise the runtime under a concurrent sweep, which took me an embarrassingly long time to figure out.
Happy to answer anything, including the ugly parts.
