Summary

Per-process network monitoring for your terminal with deep packet inspection. Cross-platform, sandboxed.

🤖 AI Deep Analysis

A promising cross-platform TUI tool for per-process network monitoring with DPI, ideal for developers and security enthusiasts needing quick insights without heavy setup.

✅ Pros

Cross-platform support (Linux, macOS, Windows, FreeBSD)
Per-process network monitoring with deep packet inspection
Sandboxed execution for enhanced security
Uses eBPF on Linux for efficient packet capture
TUI interface built with Ratatui for terminal use
GeoIP integration for location-based analysis

⚠️ Cons

Requires root/administrator privileges for packet capture
Limited to monitoring network traffic; no system-wide metrics
May have performance overhead on high-traffic networks
Relatively new project with smaller community

🎯 Use cases

Debugging network issues per application
Monitoring suspicious network activity for security
Analyzing bandwidth usage by process
Educational tool for understanding network protocols

⚖️ Comparison

Compared to nethogs (per-process bandwidth) and iftop (per-connection), RustNet adds DPI and GeoIP. It's more feature-rich but less mature than Wireshark, which offers deeper analysis but no per-process focus.
