Show HN: I made a Rust Terminal UI for OpenSnitch, a Linux application firewall
quadrophenia Friday, November 21, 2025
I made a Terminal UI for OpenSnitch[1], an interactive application firewall for Linux inspired by Little Snitch. I’ve always wanted to create a TUI and found the perfect excuse to make this for usage on one of my headless servers.
I wrote this in Rust to force myself to learn more, viz. async features. Super open to feedback and contributions!
