Prowlarr

Prowlarr is an open-source indexer manager and proxy built to centralize the management of torrent and Usenet indexers for media automation ecosystems like Sonarr, Radarr, Lidarr, and Readarr. It removes the need to individually configure indexers in each application by acting as a unified hub where you can add, test, and maintain all your indexer connections in one place, synchronizing them automatically with your connected *arr apps. Prowlarr supports hundreds of torrent trackers and Usenet sites including both public and private sources, with flexible configuration and health status reporting to keep your search infrastructure reliable. It also provides manual search tools, indexer statistics, and proxy support so that your downloads and queries can route through custom network layers if desired. The project is built on a .NET backend with a React-based user interface, giving it a modern web experience and broad platform compatibility across Windows, macOS, Linux, and containers.
