Little Snitch, the macOS network tool, is now available on Linux

Little Snitch, the popular macOS network monitoring and firewall tool, now has a Linux version. Built in Rust and using eBPF for kernel-level traffic interception, it offers a web-based UI suitable for remote server monitoring. The Linux version is positioned as a privacy tool rather than a security one, due to eBPF limitations that prevent deep packet inspection. It's free to download but partially closed source — the eBPF kernel component and UI are open, while the backend remains proprietary. It requires Linux kernel 6.12+ with BTF support (Ubuntu 25.04 or newer) and is available as deb packages for x86-64, ARM64, and RISCV64.
