PortPeeker

PortPeeker is a lightweight Windows utility built specifically for helping you monitor Internet connections. This way, you can identify the possible problems that may cause a slow or unresponsive network connection.

It sports a clean and straightforward interface that gives users the possibility to add details about the TCP or UDP servers. You can specify the port, pick a saving directory, and change the buffer size.

You can make the program display connection requests and messages, as well as error and disconnection notifications.

PortPeeker enables users to play or stop the monitoring process, clear the entire list that displays information about the sent traffic to a given port, select the WHOIS server, as well as perform basic editing operations for the generated information, namely cut, copy, or delete.

What’s more, data can be saved to a file, printed, or copied to the Clipboard and pasted into other third-party applications. Since it doesn’t require much computer knowledge to work with this tool, even less experienced users can master the utility with just a few clicks.

During our testing we have noticed that PortPeeker displays accurate results and without errors throughout the entire process. It doesn’t eat up a lot of CPU and memory, so it doesn’t hamper system performance, nor interfere with other programs’ functionality.

To sum things up, PortPeeker proves to be a simple-to-use application that helps you keep an eye on the network connection from one location to another. Thanks to its intuitive layout, it is suitable for beginners and professionals alike.
