Cozy

Cozy is a desktop audiobook player built for Linux workstations and personal media collections. It combines a clean GTK interface with chapter navigation, playback speed adjustment, and an offline mode to cache audio from network storage to local disk. For listeners who want focused spoken-word playback without running web containers or background services, it provides a direct, local-first listening experience.

Where Cozy fits

In homelab setups, audiobooks typically live on network storage accessed either through client-server platforms like Audiobookshelf or via generic players like VLC. Media servers provide remote streaming and device synchronization but require container daemons, web infrastructure, and ongoing maintenance. Generic desktop players avoid that overhead but treat audiobooks like music files, frequently dropping playback timestamps across long tracks. Cozy operates between these approaches as a native Linux client reading directly from local folders or network mounts without server dependencies.

The key trade-off is architecture versus mobility. Cozy does not offer web streaming, user accounts, or cross-device sync to mobile apps. Instead, it provides a self-contained workstation workflow with an offline cache feature, allowing listeners to pull books from central NAS shares to internal laptop storage before disconnecting. For administrators who already maintain file storage and want keyboard-friendly listening at a Linux desktop without another service to maintain, Cozy fits neatly into local workflows.

What it does well

• Offline storage caching: Users with audiobooks on NFS or SMB network shares can cache specific titles to internal drives, preventing playback interruption when disconnecting laptops from local networks.
• Persistent position tracking: Remembers exact playback timestamps and custom playback speeds independently for every book in the library.
• Direct filesystem ingestion: Scans directory hierarchies and extracts audio tags directly from disks via folder selection or drag-and-drop without altering file structures.
• Desktop MPRIS integration: Connects track metadata and playback controls to Linux desktop panels and hardware media keys for direct workstation control.
• Broad DRM-free codec playback: Plays unencrypted MP3, M4B, M4A, FLAC, OGG, and WAV collections through GStreamer pipelines without transcoding overhead.
