TCP Port Listener for Windows 11  |  29-Nov-2025

PortProvider 1.1

PortProvider is a small tool that makes TCP ports available. It is very suitable for end-to-end tests within the network.

 

The features:

• Provides TCP ports
• Freely selectable port number
• Multiple TCP ports with one click
  

End-to-end tests

Troubleshooting often raises the question of whether the server is not making a certain TCP port available correctly or whether the network connection is being blocked on the way to the destination - for example by a firewall. This is where PortProvider comes into play: PortProvider provides dummy TCP ports that can be used to clearly clarify the issue. The TCP ports provided by PortProvider are only used for troubleshooting and do not provide a real service.

 

Download

You can download PortProvider here as a zip file. Extract the zip file and copy the content to your program files folder, e.g. C:\Program Files (x86)\PortProvider, then run PortProvider.exe.
