FulltimeFeline released Sol, a native macOS music player designed for local libraries and Subsonic/Navidrome servers. The application delivers bit-perfect audio output, supporting formats from FLAC and ALAC to DSD and Monkey's Audio. Sol features a modern interface with grid views, an album carousel, and multi-pane browsing.

It handles podcasts, internet radio, lyrics, and a full metadata editor with thirty fields. The player includes gapless playback, crossfade, a parametric equalizer, and Replay Gain with clipping protection. Users can match sample rates and bit depths for their DAC.

The software supports two-way sync with Navidrome and Subsonic servers, podcast imports from Apple Podcasts, and Last.fm scrobbling. Sol is free, open source, and ad-free, with no subscriptions or in-app purchases. It is available via Homebrew, signed notarized builds, or source compilation.

The app requires macOS 14 or later and Xcode 26 for development. It features Apple Script support, sixteen Shortcuts actions, and Discord Rich Presence. Sol is translated into 34 languages with no telemetry or analytics.
