See what's on your network

LocalLAN is a network scanner for Mac. It shows you what is on the network you're connected to — and is honest about what it could not establish.

Scan a subnet and get devices with names, manufacturers, open ports and inferred roles. Compare a scan with an earlier one to see what arrived, what left and what changed. See which Wi-Fi channels are crowded and where your access point would be better off. Browse every Bonjour service on the network, live. Save a report — with a summary and charts up front — that you can hand to somebody else.

LocalLAN Pro, a one-time purchase, adds switch port mapping over SNMP, multi-subnet sites, and scheduled monitoring — for people who run managed network equipment.
