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

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

    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.

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