Bazarr

TAS Score: S3/3 — D5/5 — A3 / T2

Brief Description

Automated subtitle manager for Radarr and Sonarr. Searches multiple subtitle providers, downloads the best match for your movies and TV shows, and syncs them automatically. Supports 20+ subtitle sources and automatic subtitle synchronization.

Architectural Role

Applications/media layer: companion to the *arr stack. Monitors your Radarr and Sonarr libraries, detects missing subtitles, and downloads them automatically. Essential for non-English content or accessibility.

Technical Autonomy

  • ✅ Works without internet (existing subtitles stay)
  • ✅ Stores data locally (SQLite database, subtitle files)
  • ✅ Does not require external accounts for basic providers
  • ✅ Subtitles are standard .srt/.ass files — portable
  • ⚠️ Needs internet to search subtitle providers
