Motivated by concerns over foreign-controlled software and the lack of a good GUI firewall on Linux, they built the tool using eBPF for kernel-level traffic interception, Rust for the backend, and a web UI for remote monitoring. The kernel component and UI are open source; the rules/blocklist backend is free but closed source. The post also shares observations on Linux vs macOS network verbosity: Ubuntu had 9 system processes making connections over a week vs 100+ on macOS. Requires Linux kernel 6.12+, with potential for 5.17+ support via contributions. ## Full article daily.dev links to this article rather than hosting it.
