Gnome Feeds is a minimal RSS/Atom feed reader written in Python 3 and GTK+ 3.
It offers a simple user interface that only shows the latest news from your subscriptions. Articles are shown in a web view by default, with javascript disabled for a faster and less intrusive user experience. There’s also a reader mode included, built from the one GNOME Web/Epiphany uses.
