    Powerful control for the tech-savvy. More free firewall blocking options than Glasswire, which only allows 2 blocks for free.

    It's just like glasswire except for the fact that portmaster has more features than glasswire, and it is also for more advanced users.

    It's Open Source and the internals are much better documented, no security tool is perfect but at least here if you're a professional you can see how to works to know what it is and is not capable of. However with GlassWire they just give generic help desk responses whenever you ask questions, either because they don't know or are just trying to cover it up for marketing.

    Little Snitch doesn't provide detailed statistics on a longer time base but is more intended for real time. It is however a great application and I would call it a "reverse firewall".
