FLOSS alternative to subsonic, supporting its many clients

  • browsing by folder (keeping your full tree intact) see here
  • browsing by tags (using taglib - supports mp3, opus, flac, ape, m4a, wav, etc.)
  • on-the-fly audio transcoding and caching (requires ffmpeg) (thank you spijet)
  • jukebox mode (thank you lxea)
  • support for podcasts (thank you lxea)
  • pretty fast scanning (with my library of ~27k tracks, initial scan takes about 10m, and about 5s after incrementally)
  • multiple users, each with their own transcoding preferences, playlists, top tracks, top artists, etc.
  • last.fm scrobbling
  • listenbrainz scrobbling (thank you spezifisch, lxea)
  • artist similarities and biographies from the last.fm api
  • multiple genre support (see GONIC_GENRE_SPLIT to split tag strings on a character, eg. ;, and browse them individually)
  • a web interface for configuration (set up last.fm, manage users, start scans, etc.)
  • support for the album-artist tag, to not clutter your artist list with compilation album appearances
  • written in go, so lightweight and suitable for a raspberry pi, etc. (see ARM images below)
  • newer salt and token auth
  • tested on airsonic-refix, symfonium, dsub, jamstash, sublime music, soundwaves, stmp, strawberry, and ultrasonic


the default login is admin/admin.
password can then be changed from the web interface

#...with docker

#multiple folders support (v0.15+)

gonic supports multiple music folders. this can be handy if you have your music separated by albums, compilations, singles. or maybe 70s, 80s, 90s. whatever.

if you're running gonic with the command line, stack the -music-path arg

$ gonic -music-path /path/to/albums -music-path /path/to/compilations

if you're running gonic with ENV_VARS, or docker, try separate with a comma


if you're running gonic with the config file, you can repeat the music-path option

music-path /path/to/albums
music-path /path/to/compilations

after that, most subsonic clients should allow you to select which music folder to use. queries like show me "recently played compilations" or "recently added albums" are possible for example.

#directory structure

when browsing by folder, any arbitrary and nested folder layout is supported, with the following caveats:

  • Files from the same album must all be in the same folder
  • All files in a folder must be from the same album
