Quasarr connects JDownloader with Radarr, Sonarr and LazyLibrarian. It also decrypts links protected by CAPTCHAs.
Quasarr pretends to be both Newznab Indexer and SABnzbd client. Therefore, do not try to use it with real usenet
indexers. It simply does not know what NZB files are.
Quasarr includes a solution to quickly and easily decrypt protected links. Active monthly Sponsors get access to SponsorsHelper to do so automatically. Alternatively, follow the link from the console output (or discord notification) to solve CAPTCHAs manually. Quasarr will confidently handle the rest. Some CAPTCHA types require Tampermonkey to be installed in your browser.
- Set up and run FlareSolverr 3.
- Set up and run JDownloader 2.
- Follow the next steps.
- Ensure your running FlareSolverr is reachable by Quasarr.
- Provide your FlareSolverr URL to Quasarr during the setup process.
- The full URL must include the version path, e.g.,
http://192.168.1.1:8191/v1.
Tell Quasarr which sites to search for releases. It requires at least one valid source to start up.
- By default, Quasarr does not know which sites to scrape for download links.
- The setup will guide you through the process of providing valid hostnames for Quasarr to scrape.
- Do not ask for help here if you do not know which hostnames to use. Picking them is solely your responsibility.
- You may check sites like Pastebin for user‑submitted suggestions.
- Ensure your running JDownloader is connected to the My JDownloader service.
- Provide your My‑JDownloader‑Credentials to Quasarr during the setup process.
- Consider setting up a fresh JDownloader before you begin.
- JDownloader must be running and available to Quasarr.
- Quasarr will modify JDownloader’s settings so downloads can be handled by Radarr/Sonarr/LazyLibrarian.
- If using Docker, ensure that JDownloader’s download path is available to Radarr/Sonarr/LazyLibrarian with exactly the same internal and external path mapping (matching only the external path is not enough).
Set up Quasarr as a Newznab Indexer and SABnzbd Download Client:
- URL: Use the
URLfrom the API Information section of the console output (or copy it from the Quasarr web UI). - API Key: Use the
API Keyfrom the API Information section of the console output (or copy it from the Quasarr web UI). - Leave all other settings at their defaults.
Important notice for Sonarr
- Ensure all shows (including anime) are set to the Standard series type.
- Quasarr will never find releases for shows set to Anime / Absolute.
Important notice
- This feature is experimental and may not work as expected.
- Quasarr cannot help you with metadata issues, missing covers, or other LazyLibrarian problems.
- Please report issues when one of your hostnames yields results through their website, but not in LazyLibrarian.
Set up Quasarr as a SABnzbd+ Downloader
- SABnzbd URL/Port: Use port and host parts from
URLfound in the API Information section of the console output (or copy it from the Quasarr web UI). - SABnzbd API Key: Use the
API Keyfrom the API Information section of the console output (or copy it from the Quasarr web UI). - SABnzbd Category: Use
docsto ensure LazyLibrarian does not interfere with Radarr/Sonarr. - Press
Test SABnzbdto verify the connection, thenSave changes.
Set up Quasarr as a Newznab Provider:
- Newznab URL: Use the
URLfrom the API Information section of the console output (or copy it from the Quasarr web UI). - Newznab API Use the
API Keyfrom the API Information section of the console output (or copy it from the Quasarr web UI). - Press
Testto verify the connection, thenSave changes.
Fix the Importing settings:
- Check
Enable OpenLibrary api for book/author information - Select
OpenLibrarybelowPrimary Information Source - Under
Import languagesadd, Unknown(and for German users:, de, ger, de-DE).
Fix the Processing settings:
- Under
Foldersadd the full Quasarr download path, typically/downloads/Quasarr/ - If you do not do this, processing after the download will fail.
To restrict results to a specific mirror, add the mirror name to the Newznab/indexer URL.
Example: Appending
/api/dropbox/will only return releases wheredropboxis explicitly mentioned in a link.
Caution: If a mirror is not available at a hostname, the release will be ignored or the download will fail. Use this option carefully.

INTERNAL_ADDRESSis required so Radarr/Sonarr/LazyLibrarian can reach Quasarr. Must include port!EXTERNAL_ADDRESSis optional and helpful if using a reverse proxy. Always protect external access with basic auth!DISCORDis optional and must be a valid Discord webhook URL.HOSTNAMESis optional and allows skipping the manual hostname step during setup.- Must be a publicly available
HTTPorHTTPslink - Must be a raw
.ini/ text file (not HTML or JSON) - Must contain at least one valid Hostname per line
ab = xyz
- Must be a publicly available
SILENTis optional and silences all discord notifications except for error messages from SponsorsHelper ifTrue.DEBUGis optional and enables debug logging ifTrue.TZis optional, wrong timezone can cause HTTPS/SSL issues
Use this only in case you can't run the docker image.
pip install quasarr

Complexity is the killer of small projects like this one. It must be fought at all cost!
We will not waste precious time on features that will slow future development cycles down. Most feature requests can be satisfied by:
- Existing settings in Radarr/Sonarr/LazyLibrarian
- Existing settings in JDownloader
- Existing tools from the *arr ecosystem that integrate directly with Radarr/Sonarr/LazyLibrarian
- Assume there are zero known issues unless you find one or more open issues in this repository.
- Still having an issue? Provide a detailed report here!
- There are no hostname integrations in active development unless you see an open pull request here.
- Pull requests are welcome. Especially for popular hostnames.
- Always reach out on Discord before starting work on a new feature to prevent waste of time.
- Please follow the existing code style and project structure.
- Anti-bot measures must be circumvented fully by Quasarr. Thus you will need to provide a working solution for new CAPTCHA types by integrating it in the Quasarr Web UI.
- Please provide proof of functionality (screenshots/examples) when submitting your pull request.
SponsorsHelper is a Docker image that solves CAPTCHAs and decrypts links for Quasarr.
Image access is limited to active monthly GitHub sponsors.
- Start your sponsorship first.
- Open GitHub Classic Token Settings
