📉 FRITZ!Box Traffic Monitor for macOS

A lightweight, native macOS menu bar application that monitors your FRITZ!Box internet traffic in real-time. Built purely with SwiftUI and Network.framework, it offers a seamless integration into the macOS menu bar without cluttering your dock.

✨ Features

• Live Traffic Graph: Visualizes Upload (top/red) and Download (bottom/blue) separately in a split-view graph.
• Native Design: Uses a compact, pixel-perfect layout that fits perfectly into the macOS menu bar.
• Auto-Discovery: Automatically finds your FRITZ!Box in the local network via TCP check (Port 49000).
• Zero Distraction: Runs as a menu bar agent (no Dock icon, no main window).
• Instant Access: Quick link to open the FRITZ!Box web interface.
• Smart Fallback: Includes a manual IP input field if auto-discovery fails.
• Auto-Start: Option to automatically launch the app at login via a simple toggle in the menu (requires macOS 13+).

🚀 Installation

1. Download the latest release from the Releases page.
2. Drag the App into your Applications folder.
3. Right-click and select Open (required for non-notarized apps) to start.

⚙️ Requirements

• macOS: 11.0 (Big Sur) or later.
• FRITZ!Box: UPnP status information must be enabled.
  • Go to Heimnetz > Netzwerk > Netzwerkeinstellungen.
  • Enable: "Statusinformationen über UPnP übertragen".

🛠️ Built With

• Swift 5
• SwiftUI (User Interface)
• Combine (Data Binding)
• Network.framework (Connection Checks)

🚀 Auto-Start on Login

You can set the app to start automatically whenever you log in to your Mac:

1. Click on the menu bar graph to open the settings popover.
2. Toggle the checkbox "Start bei Login" (Start at Login).
3. If prompted by macOS, allow the app to run in the background ("Login Item").

Note: This feature uses the modern SMAppService API and requires macOS 13 (Ventura) or newer.

🔧 How it works

The app polls the FRITZ!Box every second using the TR-064 / UPnP SOAP API (WANCommonInterfaceConfig). It retrieves NewByteReceiveRate and NewByteSendRate and visualizes the history in a custom SwiftUI Path drawing.
