Comments about Portmaster as a Alternative to NetLimiter
pros, cons and recent comments
more options, more advanced, simpler, and open source
Positive comment•

NetLimiter's primary usage is to limit speed. Portmaster doesn't limit speed. So Portmaster is irrelevant.
Negative comment•
0

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

There's no easy way to see and I have found no way to limit bandwidth. this is the core feature of NetLimiter so I cannot consider this as an alternative at all.
