   Portmaster does not provide a way to set bandwidth limits, so it is not similar enough to NetLimiter to be an alternative.

   NetLimiter's primary usage is to limit speed. Portmaster doesn't limit speed. So Portmaster is irrelevant.

   The tool is fine, easy to setup, but it can only block traffic, not limit.

   Doesn't show network usage, like how many KB is an app using.

   Dark mode, traffic shaping and light weight. I finally switched from Netlimiter Pro subscription loop thanks to this Open Source project.
   Cheers to the developer or the fort project tnodir for the active development and I look forward to it's future.

   It lacks almost all of the features NetLimiter has - it is NOT an alternative in any way.
