Free per-app network monitor for macOS, Windows and Linux. Every app is a tower in a 3D city (or a tile on a 2D map): see who it talks to, how much, what kind of traffic, and get alerts when it contacts a known malicious server. Pause or block any app. Everything is measured locally, nothing is decrypted or uploaded. The snet command line is open source.

Could you build this?
Partial The 3D/2D visualization, alerts, and threat-intel lookups are vibe-codeable, but per-app traffic attribution and blocking need OS-level hooks (macOS Network Extension, Windows WFP, Linux eBPF/netfilter) that differ across three platforms.
What it would actually take: Architecture would be a native daemon per OS that attributes sockets to processes and enforces allow/block rules, plus a UI layer (Electron, Tauri, or native) for the city view. The hard parts are the privileged network extensions and drivers, code signing and notarization, and a curated malicious-host feed. Building it well requires systems programming and OS-security expertise, not just prompting.
