quasarr 2.7.2

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

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:

🔗 https://quasarr-host.name — community guide for finding hostnames

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

Authentication is optional but strongly recommended.

• 🔐 Set USER and PASS to enable form-based login (30-day session)
• 🔑 Set AUTH=basic to use HTTP Basic Authentication instead

---

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

1. In the Newznab Settings for Quasarr, enable advanced settings.
2. Append the desired mirror name to the API Path field.

/api/dropbox/

Using the URL field will not work!

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://quasarr-host.name/ini?token=123...' \
  -e 'USER'='admin' \
  -e 'PASS'='change-me' \
  -e 'AUTH'='form' \
  -e 'SILENT'='True' \
  -e 'DEBUG'='' \
  -e 'TZ'='Europe/Berlin' \
  ghcr.io/rix1337/quasarr:latest

Parameter	Description
INTERNAL_ADDRESS	Required. Internal URL so Radarr/Sonarr/LazyLibrarian can reach Quasarr. Must include port.
EXTERNAL_ADDRESS	Optional. External URL (e.g. reverse proxy). Always protect external access with authentication.
DISCORD	Optional. Discord webhook URL for notifications.
HOSTNAMES	Optional. URL to a hostname list to skip manual setup. Must be a publicly accessible HTTP/HTTPS link, point to a raw .ini or plain text file (not HTML or JSON), and contain at least one hostname per line in the format ab = xyz.
USER / PASS	Optional, but recommended! Username / Password to protect the web UI.
AUTH	Authentication mode. Supported values: form or basic.
SILENT	Optional. If True, silences all Discord notifications except SponsorHelper error messages.
DEBUG	Optional. If True, enables debug logging.
TZ	Optional. Timezone. Incorrect values may cause HTTPS/SSL issues.

Manual setup

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

⚠️ Requires Python 3.12 (or later) and uv!

uv tool install quasarr

quasarr
  --port=8080
  --discord=https://discord.com/api/webhooks/1234567890/ABCDEFGHIJKLMN
  --external_address=https://foo.bar/
  --hostnames=https://quasarr-host.name/ini?token=123...

• --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 here.
  • 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. The simplest CAPTCHA bypass involves creating a Tampermonkey user script.
  • Please provide proof of functionality (screenshots/examples) when submitting your pull request.

SponsorsHelper

SponsorsHelper is a Docker image that solves CAPTCHAs and decrypts links for Quasarr.
Image access is limited to active monthly GitHub sponsors.

🔑 GitHub Token Setup

1. Start your sponsorship first.
2. Open GitHub Classic Token Settings
3. Name it (e.g., SponsorsHelper) and choose unlimited expiration
4. Enable these scopes:
   • read:packages
   • read:user
   • read:org
5. Click Generate token and copy it for the next steps

🔐 Quasarr API Key Setup

1. Open your Quasarr web UI in a browser
2. On the main page, expand "Show API Settings"
3. Copy the API Key value
4. Use this value for the QUASARR_API_KEY environment variable

Note: The API Key is required for SponsorsHelper to communicate securely with Quasarr. Without it, all requests will be rejected with a 401/403 error.

🐋 Docker Login

⚠️ If not logged in, the image will not download.
