Ruthless Port Scanner

Ruthless Port Scanner is a small-sized and portable tool that you can use to quickly scan an IP address for any open ports.
Since installation is not a prerequisite, you can drop the executable file in any location on the hard disk and click the EXE to run the app.
There is also the possibility of saving Ruthless Port Scanner to a USB flash disk or similar storage unit, to be able to run it on any machine with minimum effort and no previous installers.
An important aspect to take into account is that the Windows registry does not get updated with new entries, and no additional files are created on the disk, leaving it clean after removing the app.
The GUI is represented by a single window with a clean and simple structure, where all you have to do is point out an IP address and port range, and start the scan with the click of a button.
The list of result shows the number and description for each port. Ruthless Port Scanner supports TCP and UDP ports. There are no other notable options provided by this software utility.
The tool has minimal impact on computer performance, running on low CPU and RAM. It does not take a long time to finish a scan, and does not cause the operating system to hang, crash or pop up error messages.
All in all, Ruthless Port Scanner offers a very simple solution to checking the open ports of an IP address, and it can be used even by those with no background in networking utilities.
