Packet Sentry is an open-source network monitoring desktop application built for developers, security researchers, and system administrators who want a lightweight, native tool for inspecting real-time network activity on their machine.

The core project is a cross-platform desktop application built with Tauri 2, Rust, React, and TypeScript. It provides:

• Live packet capture — monitors a selected network interface and plots upload/download throughput in real time
• Per-process bandwidth tracking — lists every active process with its individual network usage and allows terminating processes directly from the UI
• Network latency monitoring — continuously pings public DNS servers (Cloudflare 1.1.1.1 and Google 8.8.8.8) to give a rolling baseline of connection health

The backend is written in Rust using pcap for raw packet capture and etherparse for protocol parsing, keeping the binary small, fast, and dependency-light. The frontend runs inside a Tauri webview with no Electron overhead.

v0.1.0 — pre-built installers available for Windows (x64) and Linux (x86_64).

Download from the Packet_Sentry releases page.

Windows — requires the Npcap driver with WinPcap compatibility mode enabled.

Linux — requires libpcap. The binary must be granted cap_net_raw or run with sudo to access raw sockets.

Full setup and build instructions are in the project README.
