A media server proxy that integrates music streaming providers with your local library. Works with Jellyfin and Subsonic-compatible servers (Navidrome). When a song isn't in your local library, it gets fetched from your configured provider, downloaded, and served to your client. The downloaded song then lives in your library for next time.
THIS IS UNDER ACTIVE DEVELOPMENT
Please report all bugs as soon as possible, as the Jellyfin addition is entirely a test at this point
Using Docker (recommended):
# 1. Pull the latest image
docker-compose pull
# 2. Configure environment
cp .env.example .env
vi .env # Edit with your settings
# 3. Start services
docker-compose up -d
# 4. Check status
docker-compose ps
docker-compose logs -fThe proxy will be available at http://localhost:5274.
This service only exposes ports internally. You must use nginx to proxy to it:
server {
listen 443 ssl http2;
server_name your-domain.com;
ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
ssl_protocols TLSv1.2 TLSv1.3;

- Full Metadata: Downloaded files include complete ID3 tags (title, artist, album, track number, year, genre, BPM, ISRC, etc.) and cover art
- Organized Library: Downloads save in
Artist/Album/Trackfolder structure - Artist Deduplication: Merges local and streaming artists to avoid duplicates
- Album Enrichment: Adds missing tracks to local albums from streaming providers
- Cover Art Proxy: Serves cover art for external content
Jellyfin is a free and open-source media server. Allstarr connects via the Jellyfin API using your Jellyfin user login. (I plan to move this to api key if possible)
Compatible Jellyfin clients:
Working on getting more currently
Navidrome and other Subsonic-compatible servers are supported via the Subsonic API.
Compatible Subsonic clients:
Want to improve client compatibility? Pull requests are welcome!
These clients are not compatible with Allstarr due to architectural limitations:
- Symfonium - Uses offline-first architecture and never queries the server for searches, making streaming provider integration impossible. See details
- SquidWTF - Quality: FLAC (Hi-Res 24-bit/192kHz & CD-Lossless 16-bit/44.1kHz), AAC
- Deezer - Quality: FLAC, MP3_320, MP3_128
- Qobuz - Quality: FLAC, FLAC_24_HIGH (Hi-Res 24-bit/192kHz), FLAC_24_LOW, FLAC_16, MP3_320
Choose your preferred provider via the MUSIC_SERVICE environment variable. Additional providers may be added in future releases.
- A running media server:
- Jellyfin: Any recent version with API access enabled
- Subsonic: Navidrome or other Subsonic-compatible server
- Credentials for at least one music provider (IF NOT USING SQUIDWTF):
- Deezer: ARL token from browser cookies
- Qobuz: User ID + User Auth Token from browser localStorage (see Wiki guide)
- Docker and Docker Compose (recommended) or .NET 10.0 SDK for manual installation
-
Create your environment file
cp .env.example .env
-
Edit the
.envfile with your configuration:For Jellyfin backend:
# Backend selection BACKEND_TYPE=Jellyfin # Jellyfin server URL JELLYFIN_URL=http://localhost:8096 # API key (get from Jellyfin Dashboard > API Keys) JELLYFIN_API_KEY=your-api-key-here # User ID (from Jellyfin Dashboard > Users > click user > check URL) JELLYFIN_USER_ID=your-user-id-here # Music library ID (optional, auto-detected if not set) JELLYFIN_LIBRARY_ID=
For Subsonic/Navidrome backend:
# Backend selection BACKEND_TYPE=Subsonic # Navidrome/Subsonic server URL SUBSONIC_URL=http://localhost:4533
Common settings (both backends):
# Path where downloaded songs will be stored DOWNLOAD_PATH=./downloads # Music service to use: SquidWTF, Deezer, or Qobuz MUSIC_SERVICE=SquidWTF # Storage mode: Permanent or Cache STORAGE_MODE=Permanent
See the full
.env.examplefor all available options including Deezer/Qobuz credentials. -
Configure your client
Point your music client to
http://localhost:5274instead of your media server directly.
Tip: Make sure the
DOWNLOAD_PATHpoints to a directory that your media server can scan, so downloaded songs appear in your library.

Allstarr supports discovering and downloading playlists from your streaming providers (SquidWTF, Deezer, and Qobuz).
| Setting | Description |
|---|---|
Subsonic:EnableExternalPlaylists |
Enable/disable external playlist support (default: true) |
Subsonic:PlaylistsDirectory |
Directory name where M3U playlist files are created (default: playlists) |
How it works:
- Search for playlists from an external provider using the global search in your Subsonic client
- When you "star" (favorite) a playlist, Allstarr automatically downloads all tracks
- An M3U playlist file is created in
{DownloadPath}/playlists/with relative paths to downloaded tracks - Individual tracks are added to the M3U as they are played or downloaded
Environment variable:
# To disable playlists
Subsonic__EnableExternalPlaylists=falseNote: Due to client-side filtering, playlists from streaming providers may not appear in the "Playlists" tab of some clients, but will show up in global search results.
See the Wiki guide for detailed instructions on obtaining your Deezer ARL token.
See the Wiki guide for detailed instructions on obtaining your Qobuz User ID and User Auth Token.
- Playlist Search: Subsonic clients like Aonsoku filter playlists client-side from a cached
getPlaylistscall. Streaming provider playlists appear in global search (search3) but not in the Playlists tab filter. - Region Restrictions: Some tracks may be unavailable depending on your region and provider.
- Token Expiration: Provider authentication tokens expire and need periodic refresh.

The proxy intercepts requests from your music client and:
- Forwards library requests to your configured backend (Jellyfin or Subsonic)
- Merges results with content from your music provider
- Downloads and caches external tracks on-demand
- Serves audio streams transparently
Note: Only the controller matching your configured BACKEND_TYPE is registered at runtime, preventing route conflicts and ensuring clean API separation.
If you prefer to run Allstarr without Docker:
-
Clone the repository
git clone https://github.com/SoPat712/allstarr.git cd allstarr -
Restore dependencies
dotnet restore
-
Configure the application
Edit
allstarr/appsettings.json:For Jellyfin:
{ "Backend": { "Type": "Jellyfin" }, "Jellyfin": { "Url": "http://localhost:8096", "ApiKey": "your-api-key", "UserId": "your-user-id", "MusicService": "SquidWTF" }, "Library": { "DownloadPath": "./downloads" } }For Subsonic/Navidrome:
{ "Backend": { "Type": "Subsonic" }, "Subsonic": { "Url": "http://localhost:4533", "MusicService": "SquidWTF" }, "Library": { "DownloadPath": "./downloads" } } -
Run the server
cd allstarr dotnet runThe proxy will start on
http://localhost:5274by default. -
Configure your client
Point your music client to
http://localhost:5274instead of your media server directly.
The proxy implements the Subsonic API and adds transparent streaming provider integration:
| Endpoint | Description |
|---|---|
GET /rest/search3 |
Merged search results from Navidrome + streaming provider |
GET /rest/stream |
Streams audio, downloading from provider if needed |
GET /rest/getSong |
Returns song details (local or from provider) |
GET /rest/getAlbum |
Returns album with tracks from both sources |
GET /rest/getArtist |
Returns artist with albums from both sources |
GET /rest/getCoverArt |
Proxies cover art for external content |
GET /rest/star |
Stars items; triggers automatic playlist download for external playlists |
All other Subsonic API endpoints are passed through to Navidrome unchanged.
The proxy implements a subset of the Jellyfin API:
| Endpoint | Description |
|---|---|
GET /Items |
Search and browse library items |
GET /Artists |
Browse artists with streaming provider results |
GET /Audio/{id}/stream |
Stream audio, downloading from provider if needed |
GET /Items/{id}/Images/{type} |
Proxy cover art for external content |
POST /UserFavoriteItems/{id} |
Favorite items; triggers playlist download |
All other Jellyfin API endpoints are passed through unchanged.
External (streaming provider) content uses typed IDs:
| Type | Format | Example |
|---|---|---|
| Song | ext-{provider}-song-{id} |
ext-deezer-song-123456, ext-qobuz-song-789012 |
| Album | ext-{provider}-album-{id} |
ext-deezer-album-789012, ext-qobuz-album-456789 |
| Artist | ext-{provider}-artist-{id} |
ext-deezer-artist-259, ext-qobuz-artist-123 |
Legacy format ext-deezer-{id} is also supported (assumes song type).
Downloaded music is organized as:
downloads/
├── Artist Name/
│ ├── Album Title/
│ │ ├── 01 - Track One.mp3
│ │ ├── 02 - Track Two.mp3
│ │ └── ...
│ └── Another Album/
│ └── ...
├── Another Artist/
│ └── ...
└── playlists/
├── My Favorite Songs.m3u
├── Chill Vibes.m3u
└── ...
