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 or download clients. It simply does not know what NZB or torrent 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.

Instructions

1. Set up and run FlareSolverr 3.4.4 or later.
2. Set up and run JDownloader 2.
3. Follow the next steps.

---

FlareSolverr

1. Ensure your running FlareSolverr is reachable by Quasarr.
2. Provide your FlareSolverr URL to Quasarr during the setup process.
3. The full URL must include the version path, e.g., http://192.168.1.1:8191/v1.

---

Quasarr

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.

---

JDownloader

1. Ensure your running JDownloader is connected to the My JDownloader service.
2. 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).

Radarr / Sonarr

Set up Quasarr as a Newznab Indexer and SABnzbd Download Client:

1. URL: Use the URL from the API Information section of the console output (or copy it from the Quasarr web UI).
2. API Key: Use the API Key from the API Information section of the console output (or copy it from the Quasarr web UI).
3. 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.

---

LazyLibrarian

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

1. SABnzbd URL/Port: Use port and host parts from URL found in the API Information section of the console output (or copy it from the Quasarr web UI).
2. SABnzbd API Key: Use the API Key from the API Information section of the console output (or copy it from the Quasarr web UI).
3. SABnzbd Category: Use docs to ensure LazyLibrarian does not interfere with Radarr/Sonarr.
4. Press Test SABnzbd to verify the connection, then Save changes.

Set up Quasarr as a Newznab Provider:

1. Newznab URL: Use the URL from the API Information section of the console output (or copy it from the Quasarr web UI).
2. Newznab API Use the API Key from the API Information section of the console output (or copy it from the Quasarr web UI).
3. Press Test to verify the connection, then Save changes.

Fix the Importing settings:

1. Check Enable OpenLibrary api for book/author information
2. Select OpenLibrary below Primary Information Source
3. Under Import languages add , Unknown (and for German users: , de, ger, de-DE).

Fix the Processing settings:

1. Under Folders add the full Quasarr download path, typically /downloads/Quasarr/
2. If you do not do this, processing after the download will fail.

---

Advanced Settings

To restrict results to a specific mirror, add the mirror name to the Newznab/indexer URL.

Example: Appending /api/dropbox/ will only return releases where dropbox is 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.

To see download status information in Radarr/Sonarr

1. Open Activity → Queue → Options
2. Enable Release Title

Docker

It is highly recommended to run the latest docker image with all optional variables set.

docker run -d \
  --name="Quasarr" \
  -p port:8080 \
  -v /path/to/config/:/config:rw \
  -e 'INTERNAL_ADDRESS'='http://192.168.0.1:8080' \
  -e 'EXTERNAL_ADDRESS'='https://foo.bar/' \
  -e 'DISCORD'='https://discord.com/api/webhooks/1234567890/ABCDEFGHIJKLMN' \
  -e 'HOSTNAMES'='https://pastebin.com/raw/eX4Mpl3'
  -e 'SILENT'='True' \
  -e 'DEBUG'='' \
  ghcr.io/rix1337/quasarr:latest

• INTERNAL_ADDRESS is required so Radarr/Sonarr/LazyLibrarian can reach Quasarr. Must include port!
• EXTERNAL_ADDRESS is optional and helpful if using a reverse proxy. Always protect external access with basic auth!
• DISCORD is optional and must be a valid Discord webhook URL.
• HOSTNAMES is optional and allows skipping the manual hostname step during setup.
  • Must be a publicly available HTTP or HTTPs link
  • Must be a raw .ini / text file (not HTML or JSON)
  • Must contain at least one valid Hostname per line ab = xyz
• SILENT is optional and silences all discord notifications except for error messages from SponsorsHelper if True.
• DEBUG is optional and enables debug logging if True.

Manual setup

Use this only in case you can't run the docker image.

pip install quasarr

• Requires Python 3.12 or later
• Requires FlareSolverr
• Requires JDownloader 2 with My JDownloader

  --port=8080
  --discord=https://discord.com/api/webhooks/1234567890/ABCDEFGHIJKLMN
  --external_address=https://foo.bar/
  --hostnames=https://pastebin.com/raw/eX4Mpl3

• --discord see DISCORDdocker variable
• --external_address see EXTERNAL_ADDRESSdocker variable
• --hostnames see HOSTNAMESdocker variable

Philosophy

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

Roadmap

• 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.

Development Setup for Pull Requests

To test your changes before submitting a pull request:

Run Quasarr with the --internal_address parameter:

python Quasarr.py --internal_address=http://<host-ip>:<port>

Replace <host-ip> and <port> with the scheme, IP, and port of your host machine. The --internal_address parameter is mandatory.

Start the required services using the dev-services-compose.yml file:

CONFIG_VOLUMES=/path/to/config docker-compose -f docker/dev-services-compose.yml up

Replace /path/to/config with your desired configuration location. The CONFIG_VOLUMES environment variable is mandatory.
