Audience

Solo IT admins, home-lab users, small-business IT generalists, MSP contractors, and technical users who need practical Windows LAN visibility without an enterprise monitoring suite.

About Subnetlens

Subnetlens is a local-first Windows desktop app for network discovery, LAN monitoring, and IT troubleshooting. It scans and classifies devices, builds an interactive topology map, tracks per-device port and service history, listens for mDNS/SSDP device activity in real time, and includes 26 built-in diagnostic tools such as ping, traceroute, DNS lookup, port scan, WHOIS, GeoIP, TLS checks, HTTP header inspection, and more. Pro features include Radar monitoring, Prometheus metrics, scheduled scans, risk scoring, HTML reports, IPAM, webhooks, encrypted credential vault, SNMP topology, and multi-network profiles. Scan data stays on the user's machine unless they explicitly export it, enable webhooks, or expose the Prometheus endpoint. Subnetlens is built and code-signed by HELIOSOFT LTD and is available as a free version with an optional $79 one-time Pro license.
