Nuvola (Linux) Apps are web apps running in Nuvola Apps Runtime that provides them with more native user experience and richer desktop integration features than standard web browsers can offer. Nuvola specializes in music streaming services and offers background playback, handling of media key, integration with media player applets, Last.fm scrobbling, lyrics fetching, and much more.
Although Nuvola should work in all Linux desktop environments, we currently test only GNOME (Ubuntu, Fedora), Unity (Ubuntu), and Pantheon (elementaryOS). We hope to explore other desktops in the future.
