Polaris

Polaris is a self-hosted music streaming server designed to let you enjoy your personal music collection from any computer or mobile device. It focuses on high performance, a responsive experience, and smooth handling of very large libraries.

Key Features

• Stream a personal music library through a web-based player UI
• Supports common audio formats including FLAC, MP3, OGG, Opus, WAV, AIFF, MP4, MPC, and APE
• Browsing by album, artist, and genre, plus file tree browsing
• Powerful search with per-field queries
• Multi-user support with user-specific playlists
• Visual audio waveform display
• Dark mode and customizable color palette
• Plain-text configuration with a built-in UI editor
• Built-in interactive API documentation distributed with each installation

Use Cases

• Run a private music server for a home lab or NAS-backed music library
• Provide multi-user access to a shared household music collection
• Stream a large collection remotely to mobile devices while traveling

Limitations and Considerations

• Primarily targets personal-library streaming rather than subscription services or music discovery features
• Remote access typically requires additional networking setup (for example DNS and routing)

Polaris is well-suited for users who want a fast, clean, self-hosted alternative for streaming their own music library. Its focus on performance, large-library support, and multi-user features makes it a strong choice for home and small-team deployments.
