Port scanning
Sweeps the ports that matter and tells you what is actually listening, not what should be.
reconYa sweeps your subnet, fingerprints what answers, and keeps a live map of it on your computer, so the thing that appeared on your LAN at 3am doesn't stay a mystery until morning.
A live console for everything on your network, not a wall of scan output.
Every host on your network, grouped by subnet. Shape shows what a device is, colour shows whether it is online, idle or still unidentified. Switch between a tree and a radial view.

Click any host to see what is listening on it, with the service behind each port. Rescan a single host whenever you want a fresh look.

Round-trip time, jitter and uptime for each host, plus a record of every port that opened or closed. Spot the flaky device before someone complains about it.
View full size →
Expired certificates, risky open ports, devices nobody can identify. Each alert says what was found, on which host, and stays put until you acknowledge it.

Address, vendor, role and open ports for every device that has ever answered. Filter by IP, hostname, MAC or vendor.

Sweeps the ports that matter and tells you what is actually listening, not what should be.
Ping sweeps the range to find every box that is awake, including the ones nobody documented.
Watches ARP chatter between scans, so a device that joins quietly still gets caught.
Guesses the OS from how a host answers and resolves the MAC to a vendor. Printer or intruder: usually clear.
The whole subnet as a grid. Occupied cells light up, gaps stay dark. Your LAN at a glance.
Every sweep, every appearance, every disappearance, timestamped, so you can answer "when did that show up?"
One network, several subnets. List the CIDR blocks you actually use and scan them on their own schedule, not a covering supernet nobody asked for.
Three moves from install to a live map.
Give it a subnet. It pre-fills the one you are on. No inventory file to write first.
Ping sweep, then port scans and fingerprinting on whatever answers. ARP watching runs alongside.
The map and device grid populate live while the event log narrates. Nothing to refresh.
Download the app, install it, hit scan. Every feature is unlocked for 14 days. No account, no card, no key to paste until you decide to keep it.
Available first on macOS 13 Ventura or later (universal: Apple Silicon and Intel). Windows and Linux will follow. About 20 MB, no background agents.
One price, paid once. Your licence never expires; it covers every release published in the year after you buy, and the version you have keeps working after that.
More than a handful of computers, or scanning client networks for a living? Ask for volume pricing and a single invoice.
The native desktop app, licensed to you. Every feature, no device cap, no subscription. Activate once with your key and it runs offline from then on.
Not sure yet? Start the 14-day trial first. The licence unlocks the copy you already have.
Launching soon, with a 14-day free trial first.
On networks you own or administer, yes. Pointed at someone else’s, scanning ranges from rude to prosecutable depending on where you live. Scan your own kit.
No. reconYa runs as a normal app: it pings with unprivileged ICMP, reads the ARP table macOS already keeps, and probes ports with ordinary connections. The only permission it asks for is Local Network access, which macOS requires for any app that talks to other devices on your LAN.
nmap is a scalpel you run when you have a question. reconYa is the thing that keeps watching so you know a question exists: persistent inventory, a live map and a timeline, rather than one-shot output.
Your scan data never does. reconYa stores everything on your computer and has no account or telemetry. It only goes online to activate your licence key, to show whether your internet is up, and, if you turn it on, to check for new versions. The details are in the privacy page.
No, reconYa is a desktop app for the computer in front of you. It is available first on macOS; Windows and Linux will follow.
macOS comes first: macOS 13 or later, a universal build for Apple Silicon and Intel. Windows and Linux will follow.
Two ways: define multiple target networks and scan them in turn, or give one network several CIDR ranges (two floors that don't share a supernet, say) and it sweeps each in turn and merges the results into one inventory. Either way, the host it runs on has to actually route to each range.
A perpetual licence for reconYa on one computer, plus every release published in the 12 months after purchase. When that year is over the app keeps working on the last version you installed. If you want newer releases after that, renew for another year; if not, nothing changes.
No account. After you buy, Polar (our payment provider) emails you a licence key. Paste it into the app once; reconYa checks it with Polar a single time to activate it on this Mac, then runs offline. Moving to a new Mac? Remove the licence on the old one and activate on the new one. Air-gapped network? Ask for an offline licence file instead.
reconYa is not notarized by Apple yet, so the first launch of each downloaded version needs one extra confirmation: System Settings → Privacy & Security → Open Anyway. The download page walks you through it.
Fourteen days, every feature, no card. When it ends the console locks until you enter a licence, but scans keep running in the background and nothing is deleted, so buying later picks up exactly where you left off.
