Overview

Prowlarr is the indexer aggregation layer for the *arr stack. It manages all Usenet and torrent indexer connections in one place and syncs them automatically to Sonarr, Radarr, Whisparr, and LazyLibrarian — eliminating the need to configure indexers individually in each application.

Access

No external route — internal management only.

Integration Points

Prowlarr pushes its configured indexers to downstream *arr apps via their APIs. Each app is added in Prowlarr Settings → Apps:

When an indexer is added or updated in Prowlarr, it is automatically propagated to all connected apps. No manual indexer configuration in individual *arr apps is needed.

Notes / Gotchas

• FlareSolverr (currently offline) is used by Prowlarr to bypass Cloudflare-protected indexers. When FlareSolverr is down, any Cloudflare-protected indexer will fail. Configure the FlareSolverr proxy URL in Prowlarr Settings → Indexers → Proxies.
• Prowlarr's API key is required when adding Prowlarr as the indexer source in each *arr application. Find it in Prowlarr Settings → General → Security.
• Indexer categories must be correctly mapped in Prowlarr for each app (e.g. TV categories for Sonarr, movie categories for Radarr) — misconfigured categories result in wrong content being returned in searches.
