Atrium is a controller for the servers you already run. Point it at your own
machines and manage the whole stack from your phone, without a middleman
account and without anything phoning home.

It is a controller, not a media player. Atrium browses and manages your media
servers; it does not stream video.

Supported services:

* Sonarr and Radarr - library, queue, wanted, history, blocklist, system status
and the full settings tree
* Prowlarr - indexers, search and grab
* Bazarr - subtitle status, search and download
* Seerr (Overseerr and Jellyseerr) - discover, request and manage requests
* Tautulli - active streams, history, statistics and users
* qBittorrent, SABnzbd and NZBGet - transfers and queue control
* Jellyfin, Emby and Plex - library browsing, item detail, resume rows and
now-playing sessions
* Glances - CPU, memory, GPU and disk usage of the host
* Speedtest Tracker - internet speed results and history

Features:

* Multiple profiles, so a phone can carry more than one stack
* Every instance holds a local and an external URL, and Atrium picks the right
one for the network you are on
* A dashboard of at-a-glance widgets you can reorder: active downloads, now
streaming, upcoming releases, recently added, recently downloaded, requests
and server info
* Profile import and export
* Material 3 Expressive design with dynamic color, custom palettes, light and
dark themes
* An optional biometric lock

Privacy:

There is no analytics, no telemetry, no advertising and no account. Atrium
never reports anything back to its developers. Credentials are held in
encrypted storage on the device.

Artwork is loaded from your own servers, which cache it, rather than from
sites like TheTVDB or TMDB. The exception is searching for something to add
that your servers have never seen: there is nothing cached for it yet, so its
poster comes from the artwork site directly, which then sees your address.
Everything else goes only to the servers you configure.

Free software under the GPL-3.0-or-later.

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
