Is WebNowPlaying safe?

Low risk

WebNowPlaying lets any website subscribe to active media metadata and send media-control commands through a page message bridge.

WebNowPlaying runs a content script on every website and accepts wnp-info page messages without checking the page origin. A subscribing page receives active player details such as title, artist, album, cover, playback state, duration, position, volume, rating, repeat, and shuffle, and it can forward controls such as play or pause, skip, position, volume, rating, repeat, and shuffle to the active media site.

Shared hosts - 2 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data

Destinations our analysis observed WebNowPlaying contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
