What's inside

Server features.

memory

C++ server

  • checkOne single binary. The whole server is one ~10 MB statically linked executable in modern C++. Drop it on a box and run. No runtime dependencies except ffmpeg.
  • checkSQLite storage. Your catalogue lives in one SQLite database; accounts and playlists in a separate one.
  • checkRuns anywhere. A Raspberry Pi, a NAS, a spare VPS; no runtime, no container required. Binaries for arm64 and x86 provided.
database

Storage features

  • checkAutomatic scanning.Fast multi-threaded scanner watches your folders (using inotify) and automatically updates the library as you add, move or retag files.
  • checkUnified metadata. Reads ID3 tags or folder structure, then presents one clean, consistent library to every app. Uses the Subsonic rule: a folder that directly contains media is itself an album.
  • checkMusicBrainz lookups. Pulls artist and album metadata and artwork from MusicBrainz (and other sources to fill the gaps).
  • checkMulti-disc albums. Full support for box sets (inferred from folder structure or ID3 tags). Discs and track numbers stay correctly grouped and ordered.
cast

Anything anywhere

  • checkSubsonic API. Speaks the OpenSubsonic protocol, so any compatible app on iOS, Android or desktop just works.
  • checkAudio and video. Supports the Subsonic audio and video API, with some extensions to make mixed content nicer to browse.
  • checkBuilt-in web player. Open a browser, sign in, and you're listening; nothing extra to install.
  • checkChromecast. Send audio straight from the server to any Chromecast on your network, from any browser (uses its own Chromecast implementation).
  • checkTranscoding. Automatic on-the-fly transcoding of audio and video using ffmpeg, with optional cache.
group

Multi-user

  • checkMultiple accounts. Everyone gets their own login, playlists and listening history, all from one instance.
  • checkDirect uploads. An upload API endpoint lets you add whole albums right from the web player.
  • checkShare with deep links.Share links to music on your server that take you straight to the shared track.
