Jackett is a self-hosted background service that functions as a BitTorrent tracker aggregator and proxy. It enables automated media management applications to query multiple torrent indexers simultaneously by translating standardized search requests into site-specific formats and consolidating the resulting data into a single, unified feed.
The service distinguishes itself through an adapter-based architecture that handles the complexities of disparate tracker interfaces and security protocols. It integrates with external proxy services to bypass anti-bot challenges and maintain persistent access to protected remote data sources. Additionally, the application includes a metadata resolution pipeline that maps unique media identifiers to human-readable titles using external databases to ensure accurate content matching.
Beyond its core aggregation capabilities, the software provides local result caching to minimize redundant network traffic and improve response times. It is designed for continuous operation, supporting installation as a persistent system service that manages its own lifecycle and restarts automatically to ensure availability.
