Objective-See: An Open Source Project Org for Apple Privacy and Security

While searching for small tools today, I found they have built a bunch of open-source software for macOS, mostly related to privacy and security.

KnockKnock: See what background processes, daemons, launch items, kernel extensions, login items, browser plugins, and more are on your Mac. Much more detailed than “Login Items” (some software auto-starts in other ways).
LuLu: An open-source macOS network firewall that lets you control each application’s network connections in detail (similar to Hands Off!).
