LittleSnitch is great for MacOS; it is easily configured to alert you every time your machine makes ip/domain connections, which can then be accepted, denied, or rules made

For an open-source alternative, consider checking out - Lulu [0]. It's not as feature rich nor has impressive UI like the former but gets the main work done.

Binisoft WFC for Windows is a free outbound firewall. It was acquired by MalwareBytes awhile back, but they have not interfered with development so far.

It has some areas where improvement is needed, but the fundamentals work and the user interface design is decent.

I am surprised it's not more popular for Windows users. All of the alternatives I've tried have critical issues which made me dismiss them as unserious.

Yeah I've been using Fort on windows, it's easy to use and not closed source and full of bloat like the commonly suggested windows firewalls from various security companies.
