Prowlarr, an open source indexer manager and proxy that centralises your Usenet and BitTorrent indexers in one place, searches across all of them at once, and pushes them out to your movie, TV and music apps.
Prowlarr is an open source indexer manager and proxy for Usenet and BitTorrent users. It centralises the definitions of your indexers and trackers in one place, tests and manages them, runs searches across all of them at once from a single screen, and pushes those indexers out to the apps that consume them, so you configure an indexer once in Prowlarr rather than repeating the work in Radarr, Sonarr, Lidarr and Readarr. A clean web interface gives you a history and search view, per indexer statistics and health checks, while a documented version 1 REST API exposes the same capability for automation.
It suits anyone self hosting a media automation stack: a single point of indexer management feeding the *arr apps, a searchable proxy across many trackers, and an auditable, API driven indexer layer running inside their own cloud account.
Prowlarr normally starts with authentication switched off, which means anyone who can reach it gets full control of the application and of its API key. cloudimg closes that gap. Authentication is enforced, and a unique administrator password plus a unique API key are generated on the first boot of every instance and written to a root only file. The password is handed to Prowlarr's own account creation path, so it is stored only as a salted, heavily iterated one way hash and is never left in plain text on disk. Nothing usable is baked into the image, so no two instances ever share a credential. Prowlarr runs as a dedicated unprivileged system user inside a hardened systemd sandbox, the official release is verified against the checksum the project publishes before it is unpacked, and automatic updates are turned off so a running instance never silently drifts from the published image. An unauthenticated health endpoint is provided so load balancer probes need no credential. The base is fully patched with unattended security upgrades enabled, and every deployment is paired with a step by step deploy guide and backed by 24/7 cloudimg support.
