I Use Their products. Open source, transparent work. I think I have 3 apps permanently on at all times.

Yes, and yes. I’d been using LS for years, but the Berkeley Packet Filter started wreaking havoc a few macOS versions back. Lulu is less comprehensive, but it’s also less intrusive.

Yes, have been using Objective-See's products for many years. Highly recommend. Though, be prepare for many popups to approve 😅

LuLu's UI is a bit special, but it does the job. Not missing Little Snitch

Haha what a name. What does little snitch do?

I like LuLu, pretty good service. I’ve never used the Little Snitch, so I can’t compare it.

Yes and yes 👍

I like Little Snitch but it's closed source. LuLu definitely needs a lot of UI work. It does work ok from my limited testing. It might be unusable if you can't live without the profiles feature in Little Snitch.
