SubnetLens started from a simple frustration: the free network scanners are basic and barely maintained, while the capable tools are either cloud subscriptions or cost thousands a year per site. There wasn't a modern, local-first option that just told you what's on your network and watched it for changes — without sending your data to someone else's cloud. So we built one: a fast, visual Windows scanner that names every device, tracks how your network changes over time, and keeps 100% of the data on your machine. One-time price, no telemetry.
A few things no other consumer-priced scanner combines: - It names and identifies every device — recognizes 1,451 device types by hostname, so you see "Canon G5000 printer" or "Synology NAS," not just an IP. - Per-device port history — records the exact moment a new service opens on a device, so you catch a server that suddenly started running RDP. Enterprise tools charge thousands a year for this. - Live Mode — continuous mDNS/SSDP listening catches devices the moment they appear, between scans. - 100% local — no cloud, no telemetry, no account. Your scan data never leaves your machine. - One one-time price, with an encrypted credential vault, 26 IT tools, scheduling, SNMP, IPAM and a Prometheus endpoint all bundled in.
