Shameless plug: for anyone who wants something fully open source and terminal-based, I maintain RustNet (https://github.com/domcyrus/rustnet). It's a bit different because it's a TUI for real-time connection monitoring with deep packet inspection, not a firewall. No blocking/rules, but it's cross-platform (Linux/macOS/Windows), the entire codebase is open, and it sandboxes itself after init via Landlock with capability dropping.
I remember before Little Snitch there was ZoneAlarm for Windows[0] (here is a good screenshot[1]). No clue if the current version of ZoneAlarm does anything like that (have not used it in 2 decades). I always found it weird that Linux never really had anything like it. [0]: https://en.wikipedia.org/wiki/ZoneAlarm [1]: https://d2nwkt1g6n1fev.cloudfront.net/helpmax/wp-content/upl...
Completely forgot about ZoneAlarm. I remember using it in the early 2000s!
Why?

Anyway, this one looks great. I hope Linux distros will incorporate this or similar into the network widgets.
