It is inspired by Nagios Checker for Firefox – just without an open Firefox window all the time to monitor the network.

Nagstamon is released under the GPLv2 and free to use and modify.

Nagstamon is written in Python 3 and uses the Qt 5/6 GUI toolkit which makes it very portable. It has been tested successfully on latest Ubuntu, Debian, Fedora, Windows, NetBSD, OpenBSD, FreeBSD and macOS. It works at least with GNOME, KDE, Windows and macOS desktops.
