Port Tester

Port Tester is a neat little Java-based tool designed to help you check online connectivity for specific ports. It's perfect for network administrators who need a quick way to test connections.

Easy to Use and Portable

Since it’s Java-based, you won’t find any setup pack here. What this means is that you can simply drop the program files anywhere on your hard drive and run the JAR file right away. Pretty convenient, right?

Run It Anywhere

You can even carry Port Tester around on a USB flash drive or similar storage device! Just make sure the computer you’re using has Java installed, and you're good to go.

No Leftovers After Use

A cool thing about Port Tester is that it doesn’t mess with your Windows Registry. When you remove the program, it leaves no leftover files behind. This keeps your system nice and tidy!

Straightforward Interface

The interface of Port Tester is super simple. You’ll see a clean window where everything is laid out clearly—no complicated options here! Just type in an IP address or domain name in the provided box and click the button to run your test.

Test Multiple Ports Effortlessly

This handy tool can show results for up to 10 ports at once. If you want to try another IP address or domain name, just reset the fields and give it another go!

Performance That Delivers

Port Tester uses just a moderate amount of CPU and RAM, so it won’t slow down your computer. Plus, it responds quickly to commands and finishes tests without any errors. We didn’t encounter any crashes during our testing either! Its easy-to-use design makes it a hit with everyone.
