Deploy Quasarr in one click installation.
JDownloader bridge that exposes a Newznab indexer and SABnzbd download client for the entire Arr media stack.
What you can build with Quasarr
Quasarr is a lightweight Python service that pretends to be both a Newznab indexer and a SABnzbd download client, then dispatches every grab to JDownloader 2 through its My JDownloader cloud API. The result is a seamless bridge that lets Radarr, Sonarr, Lidarr, Prowlarr, and Magazarr search and download from one-click hosters without ever touching real Usenet or BitTorrent.
Self-hosting Quasarr on a VPS keeps the bridge online around the clock, alongside JDownloader, and includes a built-in CAPTCHA decryption flow for protected links. Active GitHub sponsors can plug in SponsorsHelper to solve CAPTCHAs automatically.
Key features of Quasarr
JDownloader bridge
Forwards every grab from Radarr, Sonarr, Lidarr, and Magazarr straight into JDownloader 2 via the My JDownloader cloud API.
Newznab indexer
Quasarr exposes a Newznab-compatible search endpoint so the Arr stack can find releases on supported one-click hosters using IMDb IDs or text queries.
SABnzbd client emulation
Acts as a SABnzbd download client so Radarr, Sonarr, and Lidarr can queue, monitor, and import completed downloads with zero changes to their workflow.
CAPTCHA decryption
Built-in link decryption handles CAPTCHA-protected releases, with optional Tampermonkey scripts and SponsorsHelper integration for automatic solving.
Category and mirror control
Per-category whitelists for hostnames and download mirrors keep your library on the sources you trust without changing Arr configuration.
Notifications and auth
Optional Discord and Telegram notifications plus form-based or HTTP Basic authentication protect the web UI and keep you in the loop.

I'm incredibly happy with Hostinger's VPS hosting! Their uptime is consistently top-notch, keeping my site running smoothly. Whenever I've needed help, their technical support team has been quick, knowledgeable, and genuinely helpful.
Everything is smooth and great with Hostinger, the AI chat bot + human chat, if AI can't resolve your question. Oh and them VPS is just fire, no ups and downs. Thank you dev team and everyone else involved. Keep it up 🚀
Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Hostinger Agent and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
