🚀 Quick Start

1. Download the latest version from Releases

2. Extract the archive to your preferred directory and run Shell.exe (Administrator privileges required for ETW and Firewall API access)

3. After startup, a network speed floating window will appear in the top-right corner of your screen, and the application will be available in the system tray

4. Right-click the floating window to access settings, or navigate to "Traffic Statistics & Analysis" for detailed monitoring and configuration

🚀 概述

NetVizor 是一个现代化、轻量级的 Windows 网络监控和防火墙管理工具，它结合了 TinyWall 的简洁性和 GlassWire 的可视化能力。以性能和用户体验为核心设计理念，提供实时网络洞察和直观的防火墙控制。

✨ 功能特性

实时进程网络监控

• 实时进程追踪 - 监控每个进程的网络连接
• 实时流量统计 - 监控每个进程的上传/下载速度
• 连接详情 - 查看协议、端口和连接状态
• 历史数据 - 追踪网络使用历史记录

防火墙管理

• 便捷规则创建 - 快速向导创建防火墙规则
• 一键阻止/允许 - 即时控制应用程序网络访问
• 规则模板 - 常见应用程序的预配置规则
• Windows 防火墙集成 - 基于 Windows 防火墙 API 构建

网络使用历史与分析

• 实时图表 - 由 ECharts 驱动的流量图表
• 进程流量分布 - 带宽使用的可视化分解
• 现代化 UI - 使用 Vue 3 构建的简洁、响应式界面

界面概览

• 悬浮窗

• 网速排行榜

• 实时监控

🚀 快速开始

1. 从 Releases 下载最新版本

2. 将压缩包解压至指定目录，运行 Shell.exe 即可（软件启动需要管理员权限，ETW 与防火墙 API 均需管理员权限）

3. 软件启动后会在电脑右上角显示网速悬浮窗，右下角系统托盘也会同时显示软件图标

4. 您可以右击悬浮窗进入设置页面，或者进入"流量统计与分析"来进行详细查看和设置
