spectraNET shows which applications use the network, how much, with whom, and whether it looks suspicious. Every connection of every program is measured on your computer and drawn as an animated 2.5D city: each app is a building, the traffic flows along the streets, and a click on anything explains in plain language what it is and what it is doing.

• Live upload and download per application, with the destinations it talks to and their names
• What kind of traffic it is: video, calls, downloads, updates, radio and satellite services
• "Is my network slow?": measures your router and the internet, and tells you whether the problem is the network or an app
• Hourly and daily history of every application
• Alerts from public threat-intelligence lists; pause, end or block an app or an address, with confirmation
• Everything is measured locally: nothing is decrypted or uploaded
• The snet command line (spectranet.snet) and the snetd service, which keeps measuring while the app is closed (settings: sudo spectranet.snetd config set KEY=VALUE)

The service measures with eBPF and needs these interfaces, connected once:

sudo snap connect spectranet:system-trace sudo snap connect spectranet:system-observe sudo snap connect spectranet:network-observe sudo snap connect spectranet:network-control sudo snap connect spectranet:process-control sudo snap restart spectranet.daemon

Members of the sudo (or wheel) group can read it.
