    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.

    It's free, doesn't nag you, and gives you a similar level of control.

    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".

    • doesn't slow down my pc, and does what it's supposed to do, not more, not less.
    • allow me to block all programs and then whitelist by picking a window and a .exe file.
    • I want want it to have the ability to prompt me for the first time a program is connecting to the Internet, so that I don't have to whilelist manually.
    • And it's free! (actually I'm willing to pay if it's not).

    It's simply not a user friendly alternative to Glasswire. It might technically have some of the same features but it's a different kind of user experience altogether
