mDNS Insight listens to multicast DNS (mDNS, also known as Bonjour or Zeroconf) on the local network, and lists each device it finds along with the DNS-SD services it advertises: printers, speakers, smart home hubs, file shares and anything else that announces itself. It decodes what those services say about themselves, so a printer's TXT records read as a model name and a list of paper sizes rather than a wall of key=value pairs.
Open it from your desktop's application menu to watch the network live in a web UI that opens in your browser. Or run it from a terminal:
mdns-insight # discover for a while, then report
mdns-insight -output-format=json # the same report, for scripts
mdns-insight -webui # the live web UI, no browser
mdns-insight -open # the live web UI, in your browser
The web UI listens on this computer only, at a port the system picks. -webui=ADDR serves it elsewhere, for example to reach it from another machine on a network you trust.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
If you’re running Kubuntu 16.04 LTS (Xenial Xerus) or later, including Kubuntu 18.04 LTS (Bionic Beaver) and Kubuntu 18.10 (Cosmic Cuttlefish), you don’t need to do anything. Snap is already installed and ready to go.
Versions of Kubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf) don’t include snap by default, but snap can be installed from the command line as follows:
sudo apt update
sudo apt install snapd
To install mDNS Insight, simply use the following command:
sudo snap install mdns-insight
Browse and find snaps from the convenience of your desktop using the snap store snap.
