Jackett

Jackett is an open-source project that acts as a proxy server, translating queries from media-management applications into tracker-specific HTTP requests and normalizing the results into a common JSON format. By consolidating hundreds of private and public torrent sites behind a single REST API, it enables Sonarr, Radarr, Lidarr, Readarr, Bazarr and similar *arr tools to search for releases automatically without each developer having to maintain separate indexer code. The software runs as a lightweight Windows service or console binary, exposes a web dashboard for adding credentials, testing connectivity and monitoring query logs, and supports advanced features such as category filtering, ratio emulation, query caching and automatic fallback mirrors. Typical use cases include building an unattended media stack that grabs new TV episodes within minutes of broadcast, synchronizing wanted lists for films in specific quality tiers, or simply unifying manual searches across niche trackers through browser bookmarks or RSS readers. Jackett is available for free on get.nero.com, where the package is pulled directly from the official GitHub releases channel via winget, ensuring the latest stable build is installed and allowing multiple indexer tools to be deployed in a single batch command.
