This is great! There are over 2,000 apps on Flathub, but there are already 360 verified apps before the feature is officially launched! These have been verified to be uploaded and controlled by their actual authors.
There’s everything from KDE apps and both first-party GNOME apps and third-party GNOME Circle apps as you might expect—but there are already big names like Firefox, Telegram, LibreOffice, OBS Studio, Plex, OnlyOffice, Kodi, GIMP, and more!
