OpenSnitch Linux Application Firewall Fork With Improvements And Bug Fixes

OpenSnitch, an application firewall for Linux, is no longer under active development. This didn't mean it was the end for this project though, because Gustavo forked it about 8 months ago, and has been constantly improving it since.

OpenSnitch (fork) is a free an open source application-level firewall for Linux that's made of a daemon (written in Go) and a GUI (PyQt5). It monitors outbound connections that your applications are trying to make, preventing or permitting their connection based on a set of rules (the user is prompted to allow or deny access when no existing rules are found). The application is inspired by Little Snitch, a commercial host-based application firewall for macOS.
