Scrobble Bridge: YouTube Music → Last.fm

Scrobble Bridge keeps your YouTube Music sign-in connected to the Scrobble Bridge desktop app or a NAS you control. The runtime can then read the listening history of the active YouTube Music account and submit eligible plays to the Last.fm account you authorize. The extension is a credential-refresh bridge; it does not scrobble by itself. Install the Scrobble Bridge desktop app first, or pair the extension with your own HTTPS NAS deployment. Privacy and control: - YouTube access is optional and requested only after you click Enable automatic refresh. - Only an allowlist of YouTube authentication cookies is read. - Cookies go directly to the desktop app through Chrome Native Messaging, or to the exact HTTPS NAS origin you approve. - Raw cookies are never stored in chrome.storage and are never sent to the project maintainer. - Remove YouTube Music access at any time from the extension popup. - No analytics, ads, hosted account, or project-operated credential relay. Scrobble Bridge is an independent open-source project and is not affiliated with Google, YouTube, or Last.fm. YouTube Music does not provide the public history API required by this project, so upstream changes may occasionally require reconnection or an extension update.
