Rocksky exposes a Jellyfin-compatible API alongside the Subsonic one. Upload your music to your private Rocksky library and stream it from any Jellyfin client — phone, desktop, car head unit — without running your own server. Bring your own S3-compatible storage for your uploaded music, or use Rocksky storage. Both options work with any Jellyfin or Navidrome-compatible client.
This is the same library, the same credentials and the same uploads as the Subsonic endpoint. Use whichever protocol your favourite app speaks; you can use both at once.

​
Step 1: Upload music

To use your own S3-compatible bucket, follow the storage setup instructions, then select Your storage on the upload page. You can also select Rocksky storage to use managed storage. Open My Library in Rocksky’s sidebar and drag your audio files (MP3, FLAC, M4A, OGG, WAV, AIFF) into the upload page. Required tags: title, artist, album, album artist, duration, album art. Need to tag your files first? MusicBrainz Picard auto-fills metadata from the MusicBrainz database.
Your uploaded music is private — only you can access and stream your files.

​
Step 2: Get an API key

Visit the API Keys page and generate a new key. You’ll use it as the password in your Jellyfin client.

​
Step 3: Configure your client

Add a new server. Most clients ask for the address first, then the credentials on a separate screen — the login screen will not list any users, because this server fronts every Rocksky account. Type your handle in manually.

Compatible apps

  • Finamp (Android, iOS)
  • Symfonium (Android)
  • Streamyfin (Android, iOS)
  • Findroid (Android)
  • Feishin (desktop)
  • …and most other Jellyfin music clients.

​
Scrobbling

Plays from any of these clients are scrobbled automatically — there’s nothing extra to wire up. Hearting a track in your client stars it on Rocksky and publishes the like to your PDS, the same as it does over Subsonic.

​
What’s there and what isn’t

Artists, albums, songs, genres, years, playlists, favourites, search, resume positions and play counts all work. There is no video library, no transcoding (clients get the original file) and no lyrics — Rocksky stores neither.
