Bazarr, the open source subtitle companion to Sonarr and Radarr, automatically finding, downloading and filing the subtitle languages you want next to your media.
Bazarr is a free, open source application that manages subtitles for the TV series and movies in your library, working alongside Sonarr and Radarr. It watches for the subtitle languages you ask for, works out which are missing or could be upgraded, searches your configured subtitle providers, downloads the best matches and files them next to the media automatically. A clean web interface shows your series and movies, a history of what has been fetched, provider and language profile configuration, and a full activity view, while a documented REST API lets you automate any of it. It suits anyone running a self hosted media library who wants subtitles handled for them rather than sourced by hand.
The cloudimg image runs Bazarr inside a dedicated virtual environment under a hardened systemd service, so it answers the moment the instance boots. Security is enforced from the first request: authentication is switched on with no default password, and a unique administrator password and API key are generated on each instance's first boot and written to a root only file, so no shared credential is ever baked into the image, and the service will not start until that secured configuration is in place. Every deployment carries a paired deployment guide and 24/7 support.
