Ampache is a self-hosted, web-based media application for people who want to stream and manage their own music and video collections. It is designed around existing organized libraries and relies on embedded tags and filenames to present content with useful metadata, rather than acting as a media organizer itself. The project is aimed at users and administrators running their own server. The README describes support materials for admins and users, a documented API, and installation/configuration guidance. It also lists the server stack it expects, including a web server, PHP, Node.js for newer releases, and a MySQL-compatible database, which indicates it is meant to be deployed and maintained like a typical PHP web application.

It stores information about the available music library, serves playback through the host machine's audio device, and lets clients control playback remotely. The project is aimed at users who want a flexible, network-accessible music player rather than a traditional desktop application. The README points users to the installation manual, user documentation, and developer documentation, indicating that MPD is meant to be integrated with separate client applications. It also documents the protocol specification, which suggests a clear client-server design for remote control, metadata access, and playlist operations.

The project includes a web-based configuration interface and supports multiple users, making it useful for shared household or personal server setups. It can transcode audio on the fly, cache transcodes, run in jukebox mode for server-side playback, handle podcasts, and integrate with services such as Last.fm and ListenBrainz. Configuration is driven by environment variables or command-line flags, and the README documents installation from source and with Docker.

mStream is a personal music streaming server aimed at people who want to access their music library remotely from a home computer or self-hosted server. It is presented as a cross-platform solution that runs on Windows, macOS, Linux, and FreeBSD, with additional support for ARM devices such as the Raspberry Pi.
