What is Blockbusterr?

Blockbusterr is an automated media discovery and decision layer for self-hosted media stacks. It connects to discovery providers like TMDB, Simkl, Trakt, MDBList, and Letterboxd to fetch trending, popular, anticipated, or watchlist content. Each candidate is evaluated against reusable rule sets that can filter by genre, language, country, year, rating, votes, keywords, networks, and runtime. The tool supports preview-first jobs to inspect decisions before enabling delivery, ranked selection cycles to share delivery slots across jobs, and delivery safeguards including budgets, repeat handling, and title exceptions. It delivers either to Radarr and Sonarr or via Jellyseerr/Seerr requests. All configuration, credentials, and SQLite history are stored in a single persistent data directory. The project is distributed as a single Docker image from ghcr.io/mahcks/blockbusterr with no required external database. It has no built-in authentication by default but supports an optional token for owner access.
