Portmaster vs NetLimiter Comments
Portmaster does not provide a way to set bandwidth limits, so it is not similar enough to NetLimiter to be an alternative.
more options, more advanced, simpler, and open source

- Portmaster is Freemium and Open Source
- Portmaster is Privacy focused, Lightweight and Decentralized































































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