Little Snitch for Linux is a newly released, free network-monitoring and outbound-connection blocking tool that uses an eBPF kernel component, a Rust backend, and a web-based UI. The article summarizes architecture choices, licensing (kernel and UI open source, backend closed-source), feature scope and limitations (e.g., eBPF resource constraints and evasion risk), and kernel compatibility (confirmed for 6.12+, potential support back to 5.17).
