Toolkit

A lightweight, native always-on-top Windows system monitor built with Tauri v2, Rust, React 19, TypeScript, and Tailwind CSS v4.

Features

• Real-Time Telemetry (sys://metrics): Event-driven Rust polling (sysinfo + Win32 battery APIs) streaming CPU usage, RAM consumption, network upload/download rates, and battery status once per second without IPC polling overhead.
• Physical Adapter Filtering: Excludes loopback (lo) and virtual adapters (VMware, Docker, WSL, Hyper-V, Tailscale, WireGuard, Npcap, Bluetooth) while accurately retaining physical Ethernet and Wi-Fi adapters.
• Idle Polling Pause: Automatically suspends background metric sampling when the widget is minimized or hidden to the system tray (Condvar-driven wakeup on show).
• Explicit EN / 中 Bilingual UI & Tray Sync: Instant in-app language toggle (EN / 中) persisted in localStorage and synchronized with native Windows system tray menu labels (set_tray_language).
• Dynamic Layout Sizing: Measures visible card stack and settings panel heights with ResizeObserver to resize cleanly without card clipping.
• Native Desktop Integration: Single-instance lock (tauri-plugin-single-instance), remembered window position (tauri-plugin-window-state), optional silent startup to tray (--autostart via tauri-plugin-autostart), and hardened Tauri v2 capabilities & CSP.

Tech Stack

• Backend: Rust 2021, Tauri v2 (tray-icon), sysinfo, windows, tauri-plugin-autostart, tauri-plugin-single-instance, tauri-plugin-window-state
• Frontend: React 19, TypeScript, Vite, Tailwind CSS v4, Lucide Icons, Vitest

Development

Prerequisites

• Windows 10 / 11 with Microsoft Edge WebView2
