Mstream

"The easiest music streaming server available" is mStream's own billing, and the claim holds up: a lightweight Node.js app that turns a folder of audio files into a private streaming service in minutes, no external database required. Its filesystem-based design is the clever part - the API mirrors your folder structure, so you can browse and play music immediately, before any library scan finishes, and your organization on disk is your organization in the app. It streams flac, mp3, wav, ogg, opus, aac, and m4a, which matters to the audiophile crowd: FLAC plays uncompressed, bit-perfect, with gapless playback for live albums and continuous mixes. The web player runs anywhere a browser does and packs personality - a Milkdrop-style visualizer (Butterchurn), playlist sharing via links, and drag-and-drop uploads straight through the file explorer. Native iOS and Android apps add the feature streaming subscriptions can't match: sync your collection to your phone for true offline playback of music you own. Multi-user support assigns separate directories and permissions per account. Resource usage is famously light - mStream is tested on multi-terabyte libraries and runs happily on a Raspberry Pi, so a small RepoCloud instance serves a lifetime's collection. GPL-licensed, with zero listening-habit telemetry.
