Prowlarr is a powerful indexer manager designed to enhance your experience in managing media downloads, whether you’re using Usenet or torrents. In the world of media automation, indexers play a crucial role as they serve as the source of content, cataloging and organizing torrents or Usenet files that are ready for download. Without these indexers, tools like Sonarr, Radarr, and Lidarr would be unable to search and retrieve media efficiently. Prowlarr simplifies this by allowing you to manage multiple indexers from a single interface, streamlining the process of content retrieval.
What makes Prowlarr particularly appealing is its versatility, as it supports both Usenet and torrent indexers, including both public and private sources. Whether you’re looking for mainstream content or niche releases, Prowlarr provides the flexibility to connect to various indexers and automatically fetch content. The ability to filter and prioritize specific indexers ensures that users can tailor their setup for the most efficient, secure, and high-quality downloads possible.
How Do Usenet Indexers Work?
Usenet operates through newsgroups, which are essentially forums where users post text and binary files. These files can be anything from movies to software, and indexers collect metadata about these files (such as file names, sizes, and other relevant information).
- Indexing Process: Indexers periodically scan Usenet newsgroups for files that are shared, and they organize this content into a searchable database.
- Search and Metadata: When you use an indexer, you search through this metadata (not the files themselves). The indexer will then provide you with a list of results, including relevant details like release date, size, and quality of the file.
- NZB Files: Once you find the content you want, Usenet indexers will generate an NZB file, which is a kind of “download recipe.” This file contains instructions for your Usenet client (like SABnzbd or NZBGet) on how to download and reassemble the content from the newsgroups.
Public vs. Private Usenet Indexers
Public Indexers:
- These are freely accessible to anyone on the internet. They don’t require any special registration or membership.
- Examples include NZBGeek and NZBMatrix.
- While they are easy to access, public indexers may have lower-quality content and slower speeds due to a larger number of users and less strict quality control.
Private Indexers:
- These are more exclusive, often requiring an invitation or a registration process.
- Private indexers tend to have higher-quality content, a more active user base, and faster download speeds.
- Examples of private Usenet indexers include NZBPlanet and DrunkenSlug.
- To gain access to private indexers, you often need to maintain a good ratio by uploading content or staying active in the community.
Popular Usenet Indexers Supported in Prowlarr
Prowlarr supports a variety of Usenet indexers, both public and private, allowing users to configure multiple sources for content discovery. Some popular Usenet indexers supported by Prowlarr include:
- NZBGeek (Private)
- NZBPlanet (Private)
- DogNZB (Private)
- Usenet-Crawler (Public)

- Choose Usenet Indexer Type: Select Usenet as the type of indexer you want to add.
- Enter API Key or Login Credentials: Depending on whether the indexer is public or private, you’ll need to enter an API key (for private indexers) or just a URL (for public ones).
- Configure Settings: You can set filters, define categories, and prioritize certain indexers over others, depending on your preferences.
- Save and Test: After configuring, save the settings and test the connection to ensure everything is working properly.
Benefits of Usenet Indexers
- High Quality: Usenet indexers generally provide access to high-quality content with little to no compression or quality degradation.
- Speed: Because Usenet operates through a direct peer-to-peer-like protocol, it often provides faster download speeds compared to torrents, especially when using high-retention indexers.
- No Leeching: Unlike torrents, you don’t have to worry about seeding files after downloading; Usenet works on a direct downloading model.
- Better Security: Usenet is less likely to have malware or fake files compared to public torrents, especially when using reliable indexers.
What are Torrent Indexers?
Torrent indexers are websites or services that catalog and organize torrent files, allowing users to search for and download content (e.g., movies, TV shows, games, software) via the BitTorrent protocol. They act as a central hub, gathering and indexing torrent metadata like file names, sizes, and seeders/leechers, which helps users easily find and download torrents.
Unlike traditional file-sharing methods, where users download files from a central server, torrents allow files to be shared directly between peers. Torrent indexers provide the necessary information to connect peers to each other, making it easier to find and share content.
How Do Torrent Indexers Work?
- Cataloging Torrents: Torrent indexers continuously crawl the web and collect metadata about available torrent files. They do not host the actual content, but rather store the metadata (e.g., filenames, categories, torrent hash values) for torrents hosted by others.
- User Searches: Users can search for specific torrents by name, category, or other criteria. The indexer returns a list of results showing available torrents and their associated metadata (size, number of seeders/leechers, health, etc.).
- Providing Magnet Links or Torrent Files: Once a user selects a torrent, the indexer typically provides a magnet link (a URL that includes the information necessary to start downloading) or a torrent file. This link/file is then used by a torrent client (e.g., qBittorrent, Deluge) to begin downloading content from other peers.
Types of Torrent Indexers
Public Torrent Indexers: Public torrent indexers are open to anyone and usually don’t require any registration or special access. They allow users to freely search and download torrents. Examples include:
- 1337x
- RARBG
- The Pirate Bay
- YTS
Public indexers are often free to use, but they can be filled with spam or lower-quality torrents. Some may contain ads, and the content available can sometimes be less reliable or secure.
- Private Torrent Indexers: Private torrent indexers are invite-only or registration-based. These require users to sign up, maintain a good sharing ratio (seed more than you download), or be invited by existing members. Private indexers typically offer:
- Higher-quality torrents (verified releases)
- Faster speeds and better security
- Less exposure to spam or fake torrents
Examples of private torrent indexers:
- IPTorrents
- TorrentLeech
- What.CD (now defunct)
To use private indexers with Prowlarr or other tools, users need to provide credentials (usually in the form of an API key or username/password) and may need to adhere to certain rules, such as maintaining a specific upload/download ratio.
Key Features of Torrent Indexers
- Searchability: The primary feature of any torrent indexer is its search functionality, allowing users to find specific files by keywords, categories, or release types (e.g., 1080p movies, TV shows, etc.).
Health of Torrents: Indexers provide information about the health of a torrent, which includes:
- Seeders: The number of users who have the complete file and are sharing it.
- Leechers: The number of users who are downloading the file but not yet fully sharing it.
A higher number of seeders typically means faster download speeds and more reliable torrents.
- Categories and Filtering: Many torrent indexers allow users to filter results by category (e.g., movies, TV, music) and other factors like release year, resolution, or torrent quality.
- Verified Torrents: Some indexers provide a system for verifying the quality and authenticity of torrents, ensuring they’re not fake or malicious.
Using Torrent Indexers with Prowlarr
Prowlarr integrates with both public and private torrent indexers to help automate your media downloading. When setting up Prowlarr, you can add these indexers and configure them based on your preferences:
- For public indexers, you can simply add their URLs and API keys.
- For private indexers, you’ll need to provide login credentials (usernames, passwords, or API keys).
Prowlarr will then search the indexers for media content based on your needs and automatically send the torrent links to your torrent client, where the downloads will begin.
Advantages of Using Torrent Indexers
- Variety of Content: Torrent indexers provide access to a wide range of content, including the latest movies, TV shows, software, and music.
- Peer-to-Peer Efficiency: The BitTorrent protocol ensures faster downloads by utilizing multiple peers simultaneously, increasing the efficiency of content sharing.
- Customization: Many indexers offer advanced filtering options, allowing users to search for specific file types, qualities, and categories.
- Access to Rare Content: Private indexers, in particular, often have access to rare or hard-to-find content that’s not available on public trackers.
Private vs. Public Indexers
When using Prowlarr or similar tools for automating media downloads, understanding the difference between private and public indexers is crucial to optimizing your setup. Here’s an explanation of both types:
Public Indexers
Public indexers are open and accessible to everyone. They do not require a membership or registration to use. Anyone with an internet connection can search and download content from these indexers without restrictions.
Characteristics:
- Open Access: No need for invites, memberships, or special permissions. Just visit the site or use the API to get content.
- Free to Use: Generally, these indexers are free, though some might have premium features available for better access or faster speeds.
- Wide Availability: Examples of popular public indexers include RARBG, 1337x, YTS, and The Pirate Bay.
- Larger User Base: Because anyone can access these indexers, they often have a larger pool of content available. However, they may also be crowded with more general or lower-quality content.
- Quality Control: Content on public indexers may not be as thoroughly curated as private ones. You may encounter more spammy or less-verified torrents.
- Less Security: Public indexers are more vulnerable to spam, fake files, and potentially malicious content.
Pros:
- Easy access with no restrictions.
- No need for an invite or special permissions.
- Wide variety of content from multiple sources.
Cons:
- Lower content quality, with more chances of encountering spammy or fake files.
- Slower speeds due to the large number of users.
- More limited control over what content is available.
Private Indexers
Private indexers are restricted to a select group of users, typically requiring an invite or a membership to access. They are often part of more exclusive communities that emphasize quality and speed.
Characteristics:
- Restricted Access: To use a private indexer, you often need to receive an invite from an existing member or register and maintain a certain ratio of uploaded and downloaded content (commonly referred to as a “seed ratio”).
- Higher Quality Content: Private indexers typically offer better quality files, as they are more closely monitored by the community. They may also have stricter standards for content uploads, ensuring higher-quality releases.
- Faster Speeds: Since private indexers typically have fewer users, the speeds tend to be faster. The sites often prioritize bandwidth for active users who contribute to the community.
- Security: Private trackers are more secure than public ones, with better protections against fake files and malware. They also provide a more organized and well-maintained catalog of media.
- Invite-Only Nature: Most private indexers work on an invitation basis, and getting access can be difficult. Some require maintaining a good ratio (seeding more than downloading) to avoid being banned.
Examples of Private Indexers:
- IPTorrents
- What.CD (formerly, now shut down)
- TorrentLeech
- PassThePopcorn
Pros:
- Higher-quality content, often with more verified and trusted uploads.
- Faster download speeds due to fewer users.
- Better security and protections against fake torrents and malware.
- Stronger community involvement and support.
Cons:
- Restricted access; you may need an invite or to maintain a good ratio.
- Can be harder to get started if you don’t already have access.
- Requires maintaining a ratio (uploading as much or more than you download), which can be difficult for newcomers.
