The tracker and indexer fabric for the autobrr ecosystem.
Harbrr is a modern tracker and indexer management platform built for autobrr, qui, cross-seed, and private tracker power users.
Manage your trackers once. Connect everything. Search less. Cache more.
Harbrr provides a centralized intelligence layer between your trackers and automation applications, reducing duplicate requests, aggregating RSS feeds, optimizing search traffic, and exposing a unified Torznab interface to your entire automation stack.
While Harbrr is built with the autobrr ecosystem in mind, it remains fully compatible with Sonarr, Radarr, Lidarr, Readarr, Mylar, Whisparr, and any Torznab-compatible application.
Most indexer managers were designed around the *arr ecosystem and later integrated with autobrr.
Harbrr takes the opposite approach.
Harbrr is being built for modern private tracker workflows from day one, with native consideration for autobrr, qui, cross-seed, and tracker-friendly automation practices while maintaining seamless compatibility with existing *arr applications.
The goal isn't simply to proxy searches.
The goal is to become the intelligent layer between automation applications and trackers.

Configure your trackers once.
Harbrr provides a single source of truth for tracker configuration, authentication, capabilities, categories, and search behavior across your automation stack.
No more duplicating tracker setup across multiple applications.
Private trackers are a shared resource.
Today, multiple applications often poll the same tracker for nearly identical information.

One request. Multiple consumers.
Benefits include:
- Reduced tracker load
- Fewer duplicate requests
- Lower API utilization
- Faster downstream processing
- Better private tracker citizenship
- Improved scalability for larger automation stacks
A single release can trigger multiple searches from multiple applications.
Instead of repeatedly sending identical searches to the same tracker, Harbrr is designed to intelligently reuse cached results whenever possible.
This reduces:
- Duplicate tracker queries
- Search latency
- Tracker load
- API consumption
- Unnecessary traffic
Harbrr is designed to complement autobrr workflows rather than simply coexist with them.
Planned optimizations include:
- Shared tracker intelligence
- Smarter RSS processing
- Release reuse across applications
- Reduced tracker load
- Improved automation efficiency
- Tracker-friendly polling strategies
Harbrr is designed to work alongside qui as part of a modern automation ecosystem.
By centralizing tracker access and search intelligence, Harbrr can provide a common foundation that multiple services can leverage without independently hammering the same trackers.
Cross-seeding has unique requirements that traditional indexer managers often overlook.
Harbrr is being designed with cross-seed workflows in mind, including:
- Smarter release matching
- Search reuse and aggregation
- Reduced duplicate tracker activity
- Freeleech-aware matching
- Optional freeleech bypass logic
- Better reuse of existing tracker results
Harbrr is built around Cardigann-compatible indexer definitions.
The project aims to leverage the extensive tracker definition ecosystem established by Cardigann, Jackett, and Prowlarr while modernizing the execution engine and overall architecture.
This allows users to benefit from a mature tracker ecosystem without requiring an entirely new definition format.
Harbrr works with:
- autobrr
- qui
- cross-seed
- Sonarr
- Radarr
- Lidarr
- Readarr
- Mylar
- Whisparr
- Any Torznab-compatible application
Existing workflows continue to work while benefiting from Harbrr's centralized intelligence and optimization layer.
Harbrr is written entirely in Go.
Benefits include:
- Lightweight deployment
- Fast startup times
- Low memory footprint
- Single binary distribution
- Docker-first deployments
- Cross-platform support
- Built-in interactive API docs (Swagger UI at
/api/docs)
Private trackers should be treated as a shared resource.
Many automation stacks unintentionally generate excessive duplicate traffic through repeated RSS polling, repeated searches, and disconnected application behavior.
Harbrr exists to solve that problem.
Rather than every application independently talking to every tracker, Harbrr provides a centralized intelligence layer that can aggregate, cache, optimize, and distribute tracker data throughout your automation ecosystem.
The result is a cleaner architecture, lower tracker load, and a better experience for both users and tracker operators.
