quasarr 1.28.1

Quasarr connects JDownloader with Radarr, Sonarr and LazyLibrarian. It also decrypts links protected by CAPTCHAs.

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.

Instructions

Instructions

1. Set up and run JDownloader 2
2. Configure the integrations below
3. (Optional) Set up FlareSolverr 3 for sites that require it

Finding your Quasarr URL and API Key
Both values are shown in the console output under API Information, or in the Quasarr web UI.

---

FlareSolverr (Optional)

FlareSolverr is optional but required for some sites (e.g., AL) that use Cloudflare protection. You can skip FlareSolverr during setup and configure it later via the web UI.

If using FlareSolverr, provide your URL including the version path:

http://192.168.1.1:8191/v1

Note: Sites requiring FlareSolverr will show a warning in the console when it's not configured.

Quasarr

⚠️ Quasarr requires at least one valid hostname to start. It does not provide or endorse any specific sources, but community-maintained lists are available:

🔗 quasarr-hostnames.pages.dev — third-party guide for finding hostnames

📋 Alternatively, browse community suggestions via pastebin search (login required).

---

JDownloader

⚠️ If using Docker: JDownloader's download path must be available to Radarr/Sonarr/LazyLibrarian with identical internal and external path mappings! Matching only the external path is not sufficient.

1. Start and connect JDownloader to My JDownloader
2. Provide your My JDownloader credentials during Quasarr setup

Fresh install recommended

Consider setting up a fresh JDownloader instance. Quasarr will modify JDownloader's settings to enable Radarr/Sonarr/LazyLibrarian integration.

---

Radarr / Sonarr

⚠️ Sonarr users: Set all shows (including anime) to the Standard series type. Quasarr cannot find releases for shows set to Anime/Absolute.

Add Quasarr as both a Newznab Indexer and SABnzbd Download Client using your Quasarr URL and API Key.

Show download status in Radarr/Sonarr

Activity → Queue → Options → Enable Release Title

Restrict results to a specific mirror

Append the mirror name to your Newznab URL:

/api/dropbox/

Only releases with dropbox in a link will be returned. If the mirror isn't available, the release will fail.

---

LazyLibrarian

⚠️ Experimental feature — Report issues when a hostname returns results on its website but not in LazyLibrarian.

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'='' \
  -e 'TZ'='Europe/Berlin' \
  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.
• TZ is optional, wrong timezone can cause HTTPS/SSL issues

Manual setup

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

pip install quasarr

• Requires Python 3.12 or later

  --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.
  • A short guide to set up required dev services is found in /docker/dev-setup.md
  • 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
