All your indexers. One place. Plus a few you won't find anywhere else.

What is Prowlarr?

Prowlarr is an indexer manager and proxy for the arr stack. Configure your indexers once in Prowlarr, and it syncs them automatically to Sonarr, Radarr, Lidarr, Readarr, and Mylar — no per-app indexer setup required. It supports both Torrent Trackers and Usenet Indexers from a single dashboard.

On ElfHosted, Prowlarr is pre-configured and comes with three exclusive internal indexers built specifically for the platform.

Key Features

• 🔄 Single sync: Configure indexers once, push to all your arr apps automatically
• 📡 Torrent + Usenet: Manages both tracker types from one interface
• 🌐 FlareSolverr support: Built-in handling for Cloudflare-protected indexers — pre-configured on ElfHosted
• 🔑 API key management: Per-app API keys with full audit trail
• 🔗 TorBox integration: Works as an external indexer source for TorBox subscribers

ElfHosted-Exclusive Indexers

This is what makes Prowlarr on ElfHosted different from running it yourself or on any other host. Three internal indexers are pre-built and available only on the platform:

• 🧩 ElfZilean: Hash-based content discovery across cloud storage providers, including shared catalogs from ElfHosted users' libraries
• 🔍 ElfBitMagnet: Internal indexer that classifies content using TMDB and exposes a standard Torznab interface for querying
• ⚡ ElfStremThru: Cached content discovery from cloud storage, including results from ElfHosted's Stremio addon searches

These indexers are only accessible from within the ElfHosted platform — they're not available to self-hosters or on other managed hosting services.

Why ElfHosted?

Prowlarr is one of those apps that's easy to install and quietly annoying to maintain. Indexer configs break on upstream changes, FlareSolverr needs its own container, and keeping everything in sync across a Docker stack is a background task that adds up.

On ElfHosted, Prowlarr is pre-configured to work internally with Radarr, Sonarr, and the Stremio addon bundles. The exclusive indexers are already there. You connect your own indexer accounts and go.

Frequently Asked Questions

How do I run Prowlarr without self-hosting?
ElfHosted runs a managed Prowlarr instance for you — no Docker, no FlareSolverr container to maintain alongside it, no reverse-proxy config. You sign up, add your indexer accounts, and Prowlarr syncs them to Sonarr/Radarr/Lidarr/Readarr automatically. ElfHosted's exclusive ElfZilean, ElfBitMagnet, and ElfStremThru indexers are pre-installed on top.

What's the difference between Prowlarr and NZBHydra?
Prowlarr manages indexers across your arr apps — it's the central config hub. NZBHydra is a meta-search layer you query directly. Many users run both: Prowlarr for arr app sync, NZBHydra for manual searching and Usenet aggregation.

What are the ElfHosted-exclusive indexers?
ElfZilean, ElfBitMagnet, and ElfStremThru are internal indexers built and maintained by ElfHosted. They provide content discovery across ElfHosted's cloud storage and Stremio addon ecosystem — not available elsewhere.

Can I use Prowlarr with TorBox?
Yes. Add the prowlarr-exposed addon to your ElfHosted account to expose Prowlarr's API externally, then point TorBox at your Prowlarr instance as a custom search engine.

Do I need to run FlareSolverr myself?
No. ElfHosted provides an internal FlareSolverr instance — just enable it in your Prowlarr indexer config.
