Very cool. A clean and simple UI, a good price and an awesome added bonus: an app icon that doesn't make me cringe like Little Snitch does (I know I shouldn't care but I do).

I only wish the demo period was longer than 24 hours. But, I guess that's enough considering how simple the app is. Kudos.

Why not change the icon(s)? Something like Liteicon[1] or just a shell script.

There are plenty of app icon libraries. I use Flat.icns[2]

Cheaper than Little Snitch[0], which has been the firewall of choice for privacy-conscious Mac OS X users for over a decade. I wonder how it compares. It's a shame that neither is open source. Also, I always wondered why there was nothing like this on Linux—I write firewall rules on my servers, but I just want to use my Linux desktop. sigh

at least for ufw [1] on Ubuntu there is a GUI called gufw [2], and it's not as bad.

Does it have the ability to pop up on outgoing request? That's Little Snitch's killer feature.
