+    **NewsFlash** is an open-source, modern, simple and easy to use GTK4 news feed reader for Linux. It can be used offline or used with services like [NextCloud News](https://apps.nextcloud.com/apps/news) or [Inoreader](https://inoreader.com). It has a search feature and even a pre-defined list of sources like [TechCrunch](https://techcrunch.com) that you can add directly. It is only available as a Flatpak (on the Flathub repository).
