⚠️ WARNING: THIS PROJECT IS NOT ACTIVELY MAINTAINED AND IS PROVIDED AS-IS

• Search music - tracks, albums, playlists

• Download FLAC/MP3 music files (depending on your account plan)

  • Download tracks, albums, playlists
  • Downloaded files are fully tagged (+embedded cover art)
  • Multiple downloads can be queued

• Preview tracks before downloading

• Responsive UI - designed for desktop & mobile

⚠️ WARNING: Use with caution if your data transfer/bandwidth is limited

You need:

• A Deezer account (need HiFi for FLACs)
• A Deezer client ID, client secret
• The track decryption key. This is not included for legal reasons

Dockerfiles are provided for development & production. If you wish to run this without Docker, take a look inside either Dockerfile for usage & dependencies.

• PUBLIC_BASE (default /) - base URL/path the server is publicly served on

DOCKER_BUILDKIT=1 docker build -f Dockerfile . -t deezl \
	--build-arg PUBLIC_BASE=/

docker run --rm -it --name deezl -p 1313:80 \
	-e DEEZL_TRACK_DECRYPTION_SECRET=<...> \
	-e DEEZL_CLIENT_ID=<...> \
	-e DEEZL_CLIENT_SECRET=<...> \
	-e DEEZL_EMAIL=<...> \
	-e DEEZL_PASSWORD_MD5=<...> \
	deezl

Both frontend & backend will auto-reload/restart when modified.

• PUBLIC_PORT - port the server is publicly served on
• PUBLIC_BASE (default /) - base URL/path the server is publicly served on

DOCKER_BUILDKIT=1 docker build -f dev.Dockerfile . -t deezl-dev

(cd web/; npm i)

docker run --rm -it --name deezl-dev -p 1313:80 \
	-v $(pwd):/app:rw \
	-e PUBLIC_PORT=1313 \
	-e PUBLIC_BASE=/ \
	-e DEEZL_TRACK_DECRYPTION_SECRET=<...> \

	deezl-dev

Built with Vite, Vue 3 and UnoCSS.

Track files are downloaded as blobs, then saved using FileSaver. For albums/playlists, tracks are first downloaded, then zipped in the browser using fflate. Zip files are downloaded in multiple parts if too big.

The API server uses FastAPI.

Endpoints (summarized):

• Search, track/album/playlist info - these call Deezer APIs, parse the responses and return the parsed data. Adding ?full=1 will make responses also include the unparsed Deezer responses, useful sometimes
• Download a single track - downloads an encrypted track file → decrypts it → tags it, then returns it

deezer.py is a minimal standalone Deezer client (gateway, public API, track url fetching, track decryption). It is a bit low-level but provides access to all relevant APIs.

A more high-level (and rate limiting) client is implemented on top of it in api.py. It is used by the API server.
