Open Source Swift Wallpaper Apps

WaifuX is an open-source macOS application for discovering and managing static wallpapers, animated backgrounds, and anime content. It integrates wallpaper sources such as Wallhaven and 4K Wall, providing access to high-resolution images up to 8K. Users can search wallpapers by keywords, colors, categories, tags, and resolution. MotionBG integration enables animated desktop backgrounds, while experimental Wallpaper Engine compatibility supports scene-based and web-based wallpapers. Its built-in anime viewer aggregates content from multiple sources for convenient streaming. Users can save favorite wallpapers and videos in a personal library. WaifuX also supports individual wallpapers for multiple monitors, importing local wallpaper collections, and applying backgrounds directly from the browsing interface.
