jeffvli is an independent developer who focuses on building open-source desktop clients for self-hosted music servers, catering to audiophiles who prefer to keep their libraries under their own control. Feishin presents a lightweight, Electron-based interface that streams from any Navidrome, Subsonic or Jellyfin instance, offering fast search, smart playlists, ReplayGain, Last.fm scrobbling and a spectrum visualizer wrapped in a dark or light theme. Sonixd widens the same concept into a more powerful jukebox: it still speaks the Subsonic API but adds Jellyfin compatibility, downloads for offline listening, grid and list views for huge collections, transcoding options, multiple server profiles, global media-key support and a mini-player that docks to the taskbar. Both players appeal to users who run private servers for FLAC, MP3 or DSD libraries and want a native Windows experience without browser tabs, yet they also integrate with public Subsonic hosts when credentials are provided. Typical use cases include replacing the aging DSub or Airsonic web UI, syncing play-counts to Libre.fm, or simply enjoying gapless playback of high-resolution tracks on a laptop that stays logged in to the home NAS. The publisher’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always installing the latest release and permitting batch installation of both applications in one command.
