How we compare
Why Subnetlens?
There are free scanners and there are enterprise platforms. Subnetlens sits exactly where most IT teams need it.
vs Free Scanners
Beyond the IP list
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. See the full Subnetlens vs Advanced IP Scanner comparison →
vs Enterprise Tools
No server. No invoice.
Enterprise monitoring platforms like SolarWinds and PRTG typically run into thousands of dollars per year and need server infrastructure and a dedicated admin to run. Subnetlens is a one-time purchase from $79, installs in under a minute, and runs entirely on the machine you already have. Zero setup. Zero server.
vs Scripts & CLI
One app, not a toolbox
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.
And unlike any of them: off-the-shelf tools can't change. Subnetlens can — we build custom features and tailored versions for teams & MSPs. See custom development →
Who it's for
Built for IT professionals
Whether you manage one network or fifty, Subnetlens fits your workflow without demanding a full-time operator.
🏢
MSPs managing client networks
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.
🖥️
Solo IT admins monitoring the office
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.
🔬
Home lab enthusiasts
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.
🔐
Security teams mapping internal networks
Get a clear view of your whole subnet quickly. Spot devices with unexpected open ports, surface services you didn't know were running, prioritise what to review across your network, and document everything in a structured HTML report — all without leaving the app.
Custom development
Need it your way? We build it.
Most network tools are take-it-or-leave-it — you adapt to them, or you go without. Subnetlens is different. Need a specific feature, an integration with the systems you already run, recognition for hardware nothing else identifies, a bespoke report, or the whole app rebuilt around your workflow and your brand? We build it. You're not stuck waiting on a public roadmap — you get software shaped to your organisation.
🧩
Features built on request
Missing a report field, an export, a workflow your team lives in, or an integration with your RMM, PSA or ticketing? We scope it, quote it, and build it straight into the app — no waiting on a public roadmap.
🎛️
A version shaped to you
A build tuned to your environment — your naming, your device types, your process, even recognition for proprietary or niche hardware nothing else can identify. Not a generic, one-size-fits-all tool.
🏷️
White-label for MSPs
Ship a client-ready product under your own brand — your logo and colours on the app and on every report — so the deliverable looks like it's yours, because it is.
Examples of custom work
Integrations with your RMM / PSA or ticketing · recognition for proprietary hardware · bespoke reports & data exports · scheduled automation & alerting · tailored fleet deployment · and whatever your environment needs that off-the-shelf tools simply won't do.
Higher tiers include free small custom requests; larger work is scoped and quoted up front — no surprises. Tell us what you're trying to do and we'll tell you exactly what it takes.
Try Pro free for 7 days — no email needed. Start it from inside the app (version beta.8 and newer).

FAQ
Frequently asked questions
Is the Pro license really a one-time payment? No subscriptions?
Yes. Every Pro license — from the $79 Personal license up to the $399 Business license — is perpetual: you own it, with no subscription and no recurring charge. Each one includes 1 year of updates from the date of purchase. After that, you keep using the version you have for as long as you like — no feature lock-out, ever.
Is there a free trial?
Yes — a 7-day free trial of the full Pro tier (Subnetlens version beta.8 and newer). Start it from inside the app with one click: download Subnetlens, open the app, and hit "Try Pro free for 7 days". No email address, no card details, nothing to cancel — when the 7 days end, the app simply returns to the free tier and everything you scanned stays on your machine. One trial per machine.
Can you build custom features or a custom version for us?
Yes — it's one of the things that sets us apart. For teams and MSPs we build tailored features and custom, white-label versions of Subnetlens to fit your workflow. Higher tiers include a few free small custom requests (a minor tweak or small feature); larger work is scoped and quoted up front. Get in touch and tell us what you need.
Does it work completely offline? Is an internet connection required?
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.
How many computers can I use one Pro license on?
That depends on the license size you buy — from 3 computers (Personal, $79) up to 25 (Business, $399). Need more than 25? Get in touch for a custom quote. Whichever size you choose, you can move an activation between machines: open Settings → License, deactivate one computer, and activate the new one. If you ever get stuck — a hardware change, a reinstall, anything — email support@subnetlens.com and we'll sort it out for you.
Is any of my network data sent to your servers?
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.
What's the device classifier and how does the 1,451-pattern database work?
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.
Is this Windows only? What about macOS or Linux?
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.
What networks can I scan with this tool?
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.
Do I need administrator privileges to run it?
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.
What's the current state of the product — beta, release, what?
Subnetlens is a Release Candidate (v1.0.0-beta.8) — every feature is complete and tested, and we're polishing based on early-user feedback before dropping the "RC" label. It's fully usable today: the free tier is free forever, and Pro unlocks everything for a one-time purchase from $79 (licenses cover 3 to 25 computers — see Pricing), no subscription.
How does this compare to Advanced IP Scanner or Angry IP Scanner?
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. Full breakdowns: vs Advanced IP Scanner, vs Angry IP Scanner, vs Fing Desktop.
Is Subnetlens related to the open-source subnetlens CLI on GitHub?
No. Subnetlens (subnetlens.com) is an independent, code-signed Windows desktop application by HELIOSOFT LTD, a UK-registered company. It is not affiliated with open-source command-line projects that happen to share the name. If you are looking for the Windows network scanner with the topology map, device classification, and one-time Pro licenses, you are in the right place.
Is Subnetlens free?
The free tier is free forever: single-subnet scanning, the interactive network map, device classification, and 8 essential tools, no account required. Pro unlocks everything else with a one-time purchase from $79 (no subscription), and every machine can start a 7-day Pro trial with one click, no email needed.
Is Subnetlens safe to install?
Yes. Every installer is code-signed by HELIOSOFT LTD via Azure Trusted Signing, the download page publishes the SHA-256 checksum so you can verify your copy, and the current release shows 0 detections across 53 antivirus engines on VirusTotal (July 2026). One honest note: behaviour-based shields in a few antivirus products (notably Avast and AVG) sometimes flag network scanners as a category, including well-known tools like Advanced IP Scanner. That is a false positive: your scan data never leaves your machine, and we submit our releases to AV vendors' whitelisting programs to clear these.
