Soliton

Soliton is a native audio library player built in Rust with GPUI. It indexes your local music collection and presents it in a responsive desktop interface, with rich metadata, album artwork, multiple editions, and playback on local or network devices.

Soliton plays the albums and tracks of its library: add your music folders as sources, and everything is browsed and played from there. It is not a standalone file player: files opened from a file manager or dropped onto the window are not played directly.

Your Music, Kept Local

Browse music from multiple folders, external drives, or mounted network shares in one library. Soliton reads metadata and artwork from your files and stores its database and caches separately. Your music files, tags, and embedded artwork remain untouched.

Background indexing and filesystem monitoring keep the library up to date. When a source goes offline, its albums stay in your library and are marked unavailable until it returns.
