PortCheck

PortCheck is a super handy tool that helps you see if a specific port is open on your computer. You don't need to be a tech wizard or download a big program to do this. It's really simple and can save you time, especially if you find yourself checking ports often.

Easy to Use Interface

This app has a clean and simple interface, making it easy for anyone to use. You don’t even have to install anything! Just grab it from wherever you want, and you're good to go.

Your IP at a Glance

When you open PortCheck, it automatically finds your public IP address and shows it right in the app. By default, it checks port 80, but don't worry! If you need to check another port, just click the text field and type in your desired number.

Customize Your Check

Once you've picked your port, just hit Enter and let the app do its thing! You can even tweak how long the app waits for a response by using the F1 to F4 keys. The details about these features are on the project’s page here.

No Hassle with Your IP

If you'd rather not use your public IP for some reason, that's cool too! Just double-click on the displayed address, and change it as needed. But keep in mind that every time you launch PortCheck, it will automatically fetch your public IP.

A Simple Solution for TCP Checks

If you're looking for an easy-to-use IPv4 TCP port checker, PortCheck has got you covered. It might not have all the bells and whistles of more complex software out there, but its simplicity makes it so much easier to handle. Plus, there's no installation hassle!

Future Features?

While PortCheck does its job well right now, some extra features would be nice—like support for IPv6. But who knows? Maybe those updates will come down the line! For now though, it's definitely worth checking out.
