Windows · home appliance finder & port scanner

Port Scout

Your fridge, washer, oven, thermostat and robot vacuum are all little computers on your network. Port Scout finds them, then shows you exactly what each one has open: every port, its web pages, its encryption, and the commands it accepts. Made for beginners: every button explains itself. Same look as MAC Scout and Dialsoft's other tools.

What it does

Find every appliance. See every open door.

🔎

Finds your appliances

Lists every device on your network and puts the likely appliances first, marked LIKELY or maybe. Click one to see why.

🏷

Knows who made it

The official worldwide list of network-chip makers is built in, so it can tell a Whirlpool from an iPhone, even when the device has no name.

🚪

Every open port

Checks all 65,535 ports in a few minutes and asks each open one what it is, in plain English. Remote-login doors are shown in red.

🩺

Health monitor

Pings the appliance before, during and after every scan, with a live graph. If it drops out, you see exactly when, what was being tested, and whether it restarted.

🛡

Health guard

Old appliances can't take a fast scan. Port Scout starts gently, slows down if answers lag, and pauses if the appliance stops answering.

📈

Traffic monitor

Connections and data per second, plus every announcement the appliance makes on the network. Or just watch it, without scanning.

🌐

Hidden web pages

On every web server it tries about 35 common pages (settings, status, API) and lists the ones that answer.

🧩

API calls

Reads the appliance's UPnP descriptions and lists every command it accepts, with inputs and outputs. It never runs them.

🔐

Encryption check

Shows whether each service is encrypted, and who issued its certificate and until when.

🕐

Time, SNMP & mDNS

Extra checks a normal port scan can't see, plus a report section for anything about the appliance's clock.

📋

One-click report

Copy or save everything as plain text, ready for an email, a support ticket or a chat.

🛜

Guest & IoT networks

Appliances on a separate Wi-Fi? Type its range and Port Scout searches there too.

🎓

Made for beginners

A Start Here guide, tooltips on everything, and a manual that explains every word.

👀

Look, don't touch

Port Scout only reads. It never logs in, never sends commands and never changes your appliances.

⏸

Pause any time

Give a busy appliance a break mid-scan, then carry on where you left off. Change the speed any time, too.

🔄

Keeps itself current

Checks for new versions, shows what's new, verifies the download's fingerprint and updates itself.

Which of these is the fridge?

Click Find Appliances. Port Scout checks every address, works out who made each device's network chip, reads its name and what it announces, and puts the appliances at the top.

What's it got open?

Double-click an appliance to scan it. Each open port gets a name and a plain-English “why it matters”. Click one for everything it said.

The Open Ports tab →

Open ports with explanations

Is it coping?

Port Scout checks the appliance once a second while it scans. If the answers slow down, so does the scan. If it stops answering, the scan pauses until it's back, and the timeline records the moment, the ports being tested and whether it restarted.

What will it do if you ask?

Many appliances publish a list of the commands they accept. Port Scout reads it and shows every action with its inputs and outputs: the appliance's API, in one place.
