Datad is a lightweight Rust daemon that monitors network usage and speed on Linux systems. It integrates with NetworkManager to detect the active network connection (Wi-Fi, Ethernet, or Mobile Data), tracks data consumption, calculates upload/download speeds, and exposes the information over D-Bus for applications and user interfaces.

• Track network data usage

• Detect active network changes
• Configurable data usage limits
• Desktop notifications when limits are reached
• D-Bus API for applications and system components
