Real-time network monitor + outbound firewall — see & block every connection. Privacy-first, local-first, Rust fleet agent, SIEM exports, 8 languages. / Moniteur réseau temps réel + pare-feu sortant, agent de flotte Rust, exports SIEM. 100 % local.
Snitch is an open-source, privacy-first application firewall and real-time network monitor for macOS, Windows, and Linux. It shows every outbound connection your machine makes — which app, which server, where — via live graphs, a world map, and anomaly detection (beaconing, DNS tunneling, port scans), and blocks apps using the OS-native firewall. Everything runs locally.
Why now: It was shared on Hacker News as a Show HN with a striking hook — a Mac contacting 347 servers in one idle hour — and is pitched as a free, cross-platform Little Snitch alternative.
Who it is for: Privacy-conscious users and security folks who want Little Snitch-style per-app visibility and blocking, cross-platform and without cloud services.
