mStream

mStream is a lightweight open-source music streaming server that provides remote access and device sync for personal music collections. It serves a web-based player and supports mobile clients, letting users stream lossless and lossy formats from their own host.

Key Features

• Web-based music player with gapless playback and a Milkdrop-style visualizer.
• Supports common audio formats including FLAC, MP3, AAC, OGG and others.
• Playlist management, playlist sharing and drag-and-drop file upload via the web UI.
• Lightweight Node.js server designed to run on Windows, macOS, Linux and ARM boards (e.g., Raspberry Pi).
• Official demo interface available for previewing the web player.

Use Cases

• Stream a private music library to any device while keeping full control of data and audio files.
• Provide shared access to a household or small group's music collection with playlist sharing and user accounts.
• Run on low-power hardware (Raspberry Pi / small NAS) to serve multi-terabyte libraries with low CPU/memory overhead.

Limitations and Considerations

• Mobile apps are provided by third parties (community/third‑party clients) rather than a single official first‑party store app; availability and maintenance can vary.
• Core server is Node.js-based and relies on in-repo JavaScript libraries for metadata and fast in-memory indexing; deployment assumptions (e.g., persistence/backups) should be reviewed for large libraries.

mStream is a practical choice for users who want a simple, self-hosted music streaming solution with broad format support and a browser-first player. It emphasizes ease of setup, low resource use, and a familiar web/mobile playback experience.
