NZBHydra 2 is a meta search for newznab indexers and torznab trackers. It provides easy access to newznab indexers and many torznab trackers via Jackett. You can search all your indexers and trackers from one place and use it as an indexer source for tools like Sonarr, Radarr, Lidarr or CouchPotato.

Major Features

• Searches Anizb, BinSearch, NZBIndex and any newznab compatible indexers. Merges all results, filters them by a number of configurable restrictions, recognizes duplicates and returns them all in one place
• Add results to NZBGet or SABnzbd
• Support for all relevant media IDs (IMDB, TMDB, TVDB, TVRage, TVMaze) and conversion between them
• Query generation, meaning a query will be generated if only a media ID is provided in the search and the indexer doesn't support the ID or if no results were found
• Compatible with Sonarr, Radarr, NZBGet, SABnzbd, nzb360, CouchPotato, Mylar, LL, Sick Beard, Jackett/Cardigann, Watcher, etc.
• Search and download history and extensive stats. E.g. indexer response times, download shares, NZB age, etc.
• Authentication and multi-user support
• Automatic update of NZB download status by querying configured downloaders
• RSS support with configurable cache times
• Torrent support:
  • For GUI searches, allowing you to download torrents to a blackhole folder
  • A separate Torznab compatible endpoint for API requests, allowing you to merge multiple trackers
• Extensive configurability
• Save torrents in a black hole folder; Torznab API endpoint
• Migration of database and settings from v1

Honest recommendation: If you don't understand what any or most of that means this might not be for you. The program is designed to be very configurable and can be a bit intimidating at first. If you're just starting with usenet and its automation tools you might want to wait a bit until you use this. That being said, although there are a lot of options you'll likely never need most of them. I (the developer) use only half of the stuff that NZBHydra can do.

How to Run

Download the latest release of NZBHydra 2 for your platform. Extract it anywhere (the zip does not include a base directory) and start using the appropriate way:

• On Windows (x64) you can either start NZBHydra2.exe which will add a tray icon (give it some time) or NZBHydra2 Console.exe which will open a console window.
  • Note: Do not use the folders C:\Program Files or C:\Program Files (x86).
• On Linux:
  • On amd64 start nzbhydra2.
  • On arm64 you'll need to run the included python wrapper file.
  • If you get an error about missing libraries, install libfreetype6.
• On any other OS or architecture or as a fallback:
  • You need to install Java 17 (not lower, not higher).
  • Download the generic release. This contains python scripts and java libraries. Run either wrapper file (Python 2.7 / 3.x respectively). This should work basically everwhere.
  • The Java executable is expected to be in the PATH. If it's not and you can't/won't put it there then you need to provide the full path using the --java paramater.
• Docker: You can choose between images by hotio and binhex's or the one by LinuxServer.io.

After a while your browser should open to http://127.0.0.1:5076.

Stuff you should know

• Without a "proper" indexer that supports media ID based searches (anything unlike Binsearch, NZBINdex, Anizb, etc) automation tools like Sonarr or Radarr will not work properly
• Hydra queries indexers for the latest 100 results for a given search query and aggregates them on the GUI. That means that even if you sort the results by, say, the name then older results not yet loaded may be missing. You will never know if a certain result is available unless you click the "Load more / Load all" buttons. This may require many API hits and take some time. I recommend using queries that are specific enough to return less than 100 results.

Disclaimer

Bugs may/do exist. Don't run it on the machine where the nuclear launch codes are stored.

Development and how you can help

Generally testing and any bug reports are very welcome.

The backend is written in Java and uses Spring Boot with an H2 file database. Maven is used for dependency management and build.

Project structure:

• core: The main code for the project
• other: contains artifacts not needed during runtime and a proxy-patched version of SocksLib
• releases: is self explanatory
• shared: is shared code between modules
• tests: contains integration tests

The frontend uses AngularJS 1.x, Bower for dependency management and gulp for build.

If you plan on doing any frontend work (JS, CSS, HTML): Please contact me first and don't just create a PR for changes on the merged CSS / JS files.

Please send merge requests to the develop branch!
