Bazarr

Bazarr is a companion application for Sonarr and Radarr that automates subtitle management for movies and TV series in your media library. It searches for, downloads, and maintains subtitles according to per-show and per-movie preferences.

Key Features

• Integrates with Sonarr and Radarr to track indexed series, episodes, and movies
• Automatic search and download of missing subtitles as they become available
• Manual subtitle search with selection and proper file naming for media players
• Subtitle upgrades: periodically replaces existing subtitles when better matches are found
• Scans existing libraries for internal and external subtitles and fetches missing ones
• Download history tracking (provider, time, and what was fetched)
• Supports forced/foreign subtitles (provider-dependent) and a large set of languages
• Supports many subtitle providers, including OpenSubtitles and others

Use Cases

• Keep TV shows and movies fully subtitled in preferred languages without manual downloads
• Maintain consistent subtitle naming/placement for Plex/Jellyfin/Kodi-style playback
• Periodically improve subtitle quality by upgrading previously downloaded subtitles

Limitations and Considerations

• Does not discover media on disk by itself; it only manages items already indexed in Sonarr and Radarr
• Provider availability and matching quality can vary depending on the subtitle source

Bazarr is well-suited for media automation stacks that rely on Sonarr and Radarr and want reliable, hands-off subtitle acquisition and upkeep. It combines automation with manual controls to handle edge cases when matching is difficult.
