Atrium

Atrium is an open-source Android application for managing self-hosted media servers, download clients, and monitoring services through a unified interface. It integrates with Sonarr, Radarr, Lidarr, Prowlarr, Jellyfin, Plex, qBittorrent, and numerous other platforms. Users can manage multiple instances of each service and access them through automatically selected local or remote connections.

The application provides media browsing, torrent management, download controls, and server monitoring tools. Additional capabilities include Wake-on-LAN, biometric authentication, and secure API key storage. Built with Flutter, Atrium features a Material 3 interface with dynamic colors, customizable profiles, and configuration import and export.
