portmaster VS LuLu

There's a very good relatively new open-source GUI firewall app like this called Portmaster:

https://safing.io/

It's available for Windows and Linux

You can get your own firewall app. Portmaster by safing.io lets you open and close what ever ports you want on your windows system

amazing work OP! what's the difference between zen and portmaster? :) i would like to compare options to see which one fits my needs the best way

Portmaster itself is open source (https://github.com/safing/portmaster)

Then install https://safing.io/ (Portmaster); it's free.

There's Lulu based on Apple's Network Extension framework but there's quite a few issues with framework itself (it will briefly initiate a connection even though there's a deny rule for that address etc).

You could install WPD (https://wpd.app/), use Simplewall (https://github.com/henrypp/simplewall) and a pihole on the network to block a lot, but it's still sad that we need to do this.

Apple alternatives include LuLu (https://github.com/objective-see/LuLu)

Looking for steps to compile this GitHub project https://github.com/objective-see/LuLu

LuLu is probably the most user-friendly application.

The worst thing that could happen is that one of the governments would specifically ask Apple for the data of everyone in your area, or just you. I don't know how bad this is for you, but with open source programs like LuLu, you can see how much data your computer is sending to Apple in the background without you noticing.

There's also a free (open source) equivalent available, called Lulu: https://github.com/objective-see/LuLu

jok, https://github.com/objective-see/LuLu

Lulu is open source and free, with 7.8k stars on GitHub.

LuLu is a free alternative for LittleSnitch
