Flatpak

Electron apps don't integrate well with operating systems because they're essentially web browsers displaying local content. When Electron doesn't support specific OS features, apps using it also won't—for example, Discord lacks screen sharing on Wayland and doesn't support file portals on Flatpak.

Desktop users expect applications to auto-update like on Windows/macOS, but Linux lacks this capability. Users must rely on fragmented package managers with outdated versions, or manually manage AppImages, Flatpaks, and obscure dependencies.

Certain Linux distributions maintain outdated package versions in their repositories and don't update frequently enough. Alternative packaging formats attempted as solutions (like Flatpak forks) lack functionality and provide minimal improvement.
