Port Scanner

Port Scanner is a tiny and portable software utility whose only goal is to help users verify an IP address for any open ports.

It does not comprise complex options or configuration parameters, making it accessible to all types of users, even the ones with limited or no prior experience in networking software.

Since installation is not a prerequisite, you can put the app files in any location on the HDD and just click the EXE to run.

As an alternative, you can save Port Scanner to a mass storage device, in order to look for open ports on any machine without installing anything beforehand.

In addition to this, the app does not create new entries in the Start menu or, more importantly Windows registry, leaving the disk clean after its removal.

From the interface perspective, Port Scanner is user-friendly. Represented by a basic window with all options shown in plain sight, the tool lets users establish the IP address, port range, delay time and number of threads, as well as click a button to immediately begin scanning.

If any ports are open, they are listed below. Selected entries can be copied to the Clipboard using the global keyboard shortcut or by selecting the correspondent entry from the right-click menu. There are no other notable options.

No error dialogs were shown in our evaluation, and Port Scanner did not freeze, crash or pop up errors. It carries out port scanning rapidly and displays a message when finished. CPU and RAM usage is low, so PC performance is not affected.

Although it is not exactly feature-rich, Port Scanner is one of the simplest apps available for locating open ports on selected IP addresses, catering to all user levels.
