Little Snitch for Linux

A macOS-style network-transparency and control app is being built for Linux using eBPF at the kernel level, Rust for core components, and a web UI that can monitor remote servers. It's shipped as an early release aimed at showing (not hardening) what processes are making outbound connections and allowing one-click blocks. — If widely adopted, such tools could shift public debate and regulatory attention from opaque telemetry to demonstrable evidence of what apps and OSes actually send off-device.
