Hostnames recognised via the bundled 1,451-pattern device database.
No dashboards that need a PhD. No per-seat subscriptions. Just a fast, capable tool that stays out of your way.
Real-time event timeline + tactical-radar canvas. Sees new devices, disappeared devices, port changes, hostname changes. Magnifying-glass cursor lens for precise clicks. Anomaly detection surfaces noteworthy events automatically.
Toggle the REC indicator in the header. Continuous mDNS + SSDP listeners catch every device the moment it broadcasts — even between scans. Devices pulse with a soft halo when they speak up.
Every scan records which ports opened or closed. Timeline view per device, with "NEW since baseline" badges when a port appears that wasn't there before. Security-grade visibility no consumer scanner offers.
Per-device 0–100 score. One-click deep audit: TLS analysis, HTTP header review, default-credential probe, CVE matching against detected versions. Exports to CSV / JSON for compliance.
Pick a device, see context-aware actions: RDP / SSH / CMD here (with in-app credential modal + Vault auto-fill), camera streams, SNMP reboots, DB connection strings, IPP test-page print. Click any tile on the Explorer card to drop into a single-device workshop — Files, Ports, Web, Risk, Notes.
Identifies router / switch / server / workstation / printer / phone / IoT from 14+ signals (ports, MAC vendor, banners, mDNS, SSDP, service-banner versions, DHCP fingerprints, 1,451 bundled hostname patterns). Each device shows "Why this type?" — top 3 reasons. Free for everyone.
AES-256-GCM encrypted local storage with PBKDF2 at 600k iterations. Smart import from KeePass / 1Password / LastPass / Bitwarden exports. Auto-fills the Control Panel's shell launchers + RDP / SSH context actions. Zero cloud sync.
Cron expressions or interval presets. Quick (ARP+ping) or Full (7-step) scan per schedule. Webhook integrations for Slack, Discord, Microsoft Teams or any custom URL — SSRF-hardened. Smart retries with auto-disable.
Switch port-to-MAC mapping. Enhanced topology edges showing physical connections. Interface stats + SNMPv3 + trap receiver. Plus Sentinel — background poller watching your network while you work.
Built-in /metrics HTTP endpoint plugs into your existing Grafana / Prometheus stack. Three lines in prometheus.yml and you're scraping live device counts, port stats, scan durations.
Ctrl+K from anywhere. Fuzzy-search every device by IP / hostname / vendor, jump to any page, run common actions — all keyboard, no mouse. The classic productivity boost, ported straight from VS Code.
Ping, Traceroute, MTR, Port Scan, DNS, WHOIS, GeoIP, TLS Check, HTTP Headers, Cert Decoder, MAC Lookup, Subnet Calc, Hash Calc, Bandwidth, Format/Encode, Cron Tester, SMB Browser, and more — all integrated with streaming output + favourites.
There are free scanners and there are enterprise platforms. Subnetlens sits exactly where most IT teams need it.
Advanced IP Scanner and Angry IP Scanner are great for quick scans. Subnetlens goes further with 26 tools, real-time monitoring, scheduled automation, a credential vault, and a single-device Explorer workshop — all in one app. The topology map alone replaces three separate tools.
SolarWinds and PRTG start at $1,750+/year and require server infrastructure, a DBA, and a dedicated admin. Subnetlens is $79 once, installs in under a minute, and runs entirely on the machine you already have. Zero setup. Zero server.
Stop juggling nmap, ping, traceroute, ipconfig, and PowerShell scripts across five terminal windows. Every tool you need is one click away — with output you can read, results you can save, and devices you can target directly from the network map.
Whether you manage one network or fifty, Subnetlens fits your workflow without demanding a full-time operator.
Run scans across multiple subnets, store per-client credentials in the encrypted vault, set up scheduled monitoring for each client, and export HTML reports to share with stakeholders. All from a single laptop, no servers required.
Know what's on your network at a glance. Radar monitoring catches new or unauthorised devices automatically. Scheduled scans run while you sleep. One-click diagnostics let you investigate any device the moment something looks wrong.
Finally see your entire homelab the way you imagined it — a proper topology map with every Pi, NAS, VM, and switch visible and labelled. Explore SNMP data, monitor for new devices, and run diagnostics without switching between five different tools.
Map your attack surface quickly. Identify devices with unexpected open ports, flag unauthorised services, assess risk scores across your subnet, and document findings in a structured HTML report — all without leaving the app.
No subscriptions. No seat limits. One payment gives you everything Pro has to offer, forever.

Yes. The $79 Pro license is a perpetual license — you own it. It includes 1 year of updates from the date of purchase. After that, updates are optional at $49/year. If you choose not to renew, you keep using the version you have. No subscription, no recurring charge, no feature lock-out if you stop paying.
Subnetlens is a locally installed desktop application. All scanning, monitoring, and data storage happens on your machine. The bundled 1,451-pattern device database is part of the installer — nothing is fetched live. License activation requires a one-time internet connection, after which the license is cached locally with a 7-day offline grace period for re-validation.
No. All scan results, device data, credentials, and network maps remain exclusively on your machine. The only external communication is license activation and validation (license key + a non-identifying machine fingerprint). We never receive your IP addresses, device inventories, or any network data. Zero telemetry by design.
Every device gets typed (router / server / workstation / phone / printer / NAS / IoT / camera / etc.) via a 14-signal classifier — ports, MAC vendor, hostname patterns, HTTP/SSH banners, mDNS/SSDP services, DHCP fingerprints, TTL, port-count, and more. Hostnames get cross-checked against a hand-curated 1,451-pattern database covering 13 categories: Apple, Samsung, Xiaomi, Google, Microsoft, routers (TP-Link/Netgear/AVM/etc.), printers, IP cameras (Hikvision/Reolink/Wyze/Ring/Nest), NAS (Synology/QNAP), smart-home (Sonos/Echo/Hue), enterprise gear (Ubiquiti/Meraki/Aruba), smart TVs and gaming. When a DEFINITIVE pattern matches AND the MAC vendor agrees, classification locks at 0.95 confidence. All offline. The 1,451 patterns ship in the installer and update with releases — no auto-update or cloud sync needed.
Currently Windows only (Windows 10 and 11, 64-bit). Several core features rely on Windows-native commands (ARP, netstat, route tables, NetBIOS resolution, SMB) which makes a direct macOS/Linux port non-trivial. Cross-platform support is under evaluation for a future version. If this is important to you, let us know — the more demand we see, the higher the priority.
Any network you are authorised to scan. Subnetlens is designed for IT professionals to scan and manage networks they own or are employed to administer. Scanning networks without authorisation is illegal and against our EULA. The tool is designed for local network administration — home networks, office LANs, and client networks under your management.
Administrator privileges are recommended for full functionality. ARP table reading and certain low-level network operations work best with elevated access. The app will run without admin rights, but some scan steps (particularly ARP-based discovery) may return fewer results on tightly locked-down environments.
Subnetlens is currently in Release Candidate (v1.0.0-beta.5). All features are complete and tested; we're collecting feedback from early users before going GA. Beta builds ship with a bundled BETA-2026 key that unlocks Pro for the duration of the beta period (expires 2026-09-30). After GA, you'll need a Pro license or use the free tier.
Advanced IP Scanner and Angry IP Scanner are excellent at what they do — producing a list of discovered IPs. Subnetlens does that too, and then keeps going: 1,451-pattern device recognition, topology visualisation, real-time monitoring, 26 built-in tools, credential vault, scheduled automation, risk scoring, single-device Explorer workshop, SNMP topology, and a Pro-grade Control Panel. The difference between an IP scanner and a complete network management workbench.
Download free and scan your network in minutes. When you need the advanced features — Radar, Control Panel + Explorer, vault, all 26 tools — Pro is $79 once. No subscription. No per-device fees. No renewal required to keep using it.
