OpenSnitch is an application-level firewall for Linux. The app is inspired by Little Snitch, a host-based commercial application firewall for macOS. It’s made up of a daemon written in Go and a PyQt5 GUI.
Opensnitch monitors outgoing connections that your applications are trying to make, preventing or allowing their connection based on a set of rules (the user is prompted to allow or deny access when no existing rules are found).
The original developer of OpenSnitch mentioned in June 2019 that they are no longer working on this program, so the project has been forked (created a fork).
