Rocksky exposes a Subsonic / Navidrome-compatible API. Upload your music to your private Rocksky library and stream it from any Subsonic 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. You can also stream the same library with any Jellyfin client.

​
Step 1: Upload music

Open My Library in Rocksky’s sidebar:

To store uploads in your own S3-compatible bucket:
  1. Open Storage and click Connect storage.
  2. Enter a name, bucket, S3 endpoint, access key ID, secret access key, and region.
  3. Click Connect & verify.
  4. On the upload page, select Your storage and choose your bucket.
You can use AWS S3, Cloudflare R2, Backblaze B2, MinIO, or another S3-compatible provider. Select Rocksky storage to use managed storage instead. Drag and drop 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 Subsonic client.

​
Step 3: Configure your client

In any Subsonic / Navidrome-compatible app, add a new server with these details:
