The Nexoniq app icon
First month free for new users

Quietly watching
your network.

Nexoniq sits in your menu bar and keeps count of what's on your network. It finds the devices, identifies what they are, and records when each one was up. None of it leaves your Mac.

— How it works —

One click from the menu bar.

Click the icon and you get the online count, a 24-hour heartbeat, and your devices sorted into categories. Teal is online. Amber answered within the hour. Coral is gone.

The full window adds the 256-cell subnet map, the 7-day uptime matrix, and a panel per device showing exactly when it dropped and for how long. There is no Dock icon unless you want one.

Settings has a TechTalk section that explains how the scanning works and how the uptime figures are calculated. It's available offline.

— What it does —

Six things, done well.

Nexoniq does one job: it tells you what's there and what's not on the networks you use.

The whole window, with one server opened up.

/01

Finding what's on your network

Nexoniq probes every address several ways: ICMP and TCP, mDNS, SSDP, NetBIOS, SNMP, and banner grabs over HTTP, TLS, SSH and SMB. MAC vendor lookups use an IEEE registry bundled in the app.

/02

Printer or NAS?

A rule-based classifier turns those signals into 30 device types: routers, switches, firewalls, Macs, PCs, Linux boxes, servers, phones, TVs, printers, NAS boxes, cameras, sensors and VoIP handsets.

/03

Uptime matrix

Seven rolling days, 30 minutes per cell, every device. Each cell shows present, absent, or no data. When Nexoniq wasn't watching it says so instead of guessing.

/04

Your networks stay apart

Home, lab, office. Nexoniq tells them apart by router, rather than by address range, so three different 192.168.1.x networks never bleed into each other. It notices the change on Wi-Fi, Ethernet and VPN, and after sleep.

/05

Alerts that behave

For each device, you choose what matters: goes offline, comes back, stays down, opens a new port. Service monitors warn you before a TLS certificate expires. Short blips are filtered out, ten devices dropping at once is one notification, and quiet hours apply everywhere.

/06

CSV out

⇧⌘E exports every device and service to a file. Filter by all, online, or alerting, pick your columns, export one network or all of them. UTF-8, RFC 4180, ISO 8601.

— Philosophy —

A network monitor should tell you the truth about your network, and keep what it learns to itself.

Antti, who thinks about your privacy
— Who it's for —

Built for people who run their own things.

The home-lab tinkerer

A pfSense box, a NAS, a couple of access points, maybe a Pi or two. Nexoniq is the one window that tells you they are all still where you left them.

The one with several networks

Devices, history and alerts stay scoped to the network they belong to, and Nexoniq switches over on its own when you move. A service monitor can be public to every network, or private to one.

The privacy-minded

Your network map stays yours. Everything is stored on your Mac, and there is no Nexoniq server for it to go to.

— The promise —

One small monthly fee.

The first month is free for new users. After that, Nexoniq Pro is €2.99 / $2.99 a month, and discovery, uptime history, alerts, export and background monitoring need an active subscription. Billed through the App Store, which shows the price in your local currency. Cancel whenever.

— Questions —

The ones people actually ask.

What is Nexoniq?

A LAN monitor for macOS that lives in the menu bar. It scans your local network, identifies what each device is, and keeps a record of when every one of them was up.

Which devices does it find?

Anything that answers on the network: routers, switches, firewalls, Macs and PCs, Linux hosts and servers, phones, TVs, printers, NAS boxes, cameras, IoT sensors and VoIP phones. Thirty device types in all.

How does it identify a device?

By combining signals rather than trusting one. ICMP and TCP checks, mDNS and SSDP discovery, NetBIOS and SNMP queries, banner grabs over HTTP, TLS, SSH and SMB, and a MAC vendor lookup against the IEEE registry bundled in the app.

Does it work over Wi-Fi, Ethernet and VPN?

All three. Nexoniq recognises which network you are on by its router, keeps each one's devices and history separate, and notices when you move, including after your Mac wakes from sleep.

Can it watch a server outside my network?

Yes. Service monitors check the URLs and host:port endpoints you list, wherever they are, and can warn you before a TLS certificate expires. A monitor can be public to every network or private to one.

Where does my network data end up?

On your Mac, in the app's sandboxed container. There is no Nexoniq server, no account and no analytics, so every IP, MAC address, hostname and uptime sample stays where it was collected.

What does it cost?

New users get the first month free. After that, discovery, uptime history, alerts, CSV export and background monitoring need a Nexoniq Pro subscription at €2.99 / $2.99 a month, billed through the App Store. Elsewhere the price is set in local currency, and the App Store shows the exact amount before you subscribe.

What do I need to run it?

macOS 15 or later, on either Apple silicon or Intel. Nexoniq is a Mac App Store download, so there is nothing else to install.

— Policy —

The privacy policy.

Last updated · 11 September 2026

Nexoniq is built so that what's on your network stays on your network. This policy describes exactly what happens on your Mac, what leaves it, and what is never collected.

What stays on your Mac

All your monitoring data lives locally on your Mac, inside the app's sandboxed container, under ~/Library/Containers/. Nothing is transmitted to a Nexoniq server at any point during normal use, because there is no Nexoniq server.

  • Discovered devices. IP addresses, MAC addresses, hostnames, vendor lookups, and the device type Nexoniq decided on.
  • Networks. The router identity used to tell your networks apart, so devices and history stay scoped to the right one.
  • Configured services. The URLs and host:port endpoints you chose to monitor.
  • Uptime history. Which devices and services answered, and when, sampled every 15 minutes and kept for 7 rolling days.
  • Alerts. Your per-device alert settings and the record of what has fired.
  • Preferences. Sweep interval, quiet hours, category order, renamed devices, your notes.

MAC vendor lookups use the IEEE registry bundled inside the app. No vendor query is sent over the network.

What Nexoniq doesn't collect

Nexoniq contains no analytics, trackers, third-party SDKs, advertising identifiers, or crash-reporting services.

I have no idea how many devices you monitor, which alerts fire, how long you keep the app open, or whether you opened it today. There are no accounts, so there is nothing to associate with you in the first place.

This is verifiable. Nexoniq's App Privacy label on the Mac App Store shows "Data Not Collected" across every category. Apple enforces this label; if Nexoniq contained a tracker, it would show up there.

What Nexoniq sends

For Nexoniq to work, your Mac must send packets on the local network and HTTP requests to configured service endpoints. Specifically:

  • ICMP and TCP probes on the IP ranges you've configured. These stay on your local network.
  • HTTP/HTTPS requests to monitored service URLs. The service host sees your IP address and a standard request, just like a browser. Nexoniq is not a middleman.
  • TCP connect attempts to monitored host:port endpoints. The destination receives a connection attempt, no more.
  • Discovery and identification traffic. mDNS and SSDP go out on the local link only. NetBIOS, SNMP and the HTTP, TLS, SSH and SMB probes are aimed at devices on your own network.

Nothing in this list leaves your local network except the requests to the service endpoints you configured yourself. There is no Nexoniq server to talk to.

When you send feedback

Nexoniq does not contain a feedback form. If you'd like to send a comment, bug report, or feature request, send a regular email to hello@nexoniq.app using whichever email program you prefer.

The address is the only way to reach the author. Your email lands in a personal inbox and is usually answered within a few days.

If you'd like to include diagnostics, you may attach the debug log nexoniq-debug.txt from the app's container (structural events only; it contains no monitored hostnames or IPs). Attaching anything is entirely your choice; Nexoniq does not collect or upload diagnostics on its own.

Children's privacy

Nexoniq does not knowingly collect any information from anyone, including children. The app has a 4+ age rating on the Mac App Store, has no accounts or social features, and contains nothing directed at children.

Changes to this policy

If this policy changes materially, the updated version will be posted here with a new "last updated" date. Because Nexoniq does not have your email address or any way to contact you, I cannot notify you directly. You're welcome to bookmark this page and check back now and then.
