## Description

Quasarr connects JDownloader 2 with the *arr ecosystem (Radarr, Sonarr, Lidarr, Magazarr) and Prowlarr by pretending to be both a Newznab indexer and a SABnzbd download client. It handles CAPTCHA-protected links through a browser-based Tampermonkey userscript flow, with an optional SponsorsHelper Docker image for automated solving (requires active GitHub sponsorship). The web UI provides category management, download mirror whitelists, search hostname whitelists, and notification integrations for Discord and Telegram. It runs as a Docker container (ghcr.io/rix1337/quasarr) or via Python 3.12+ with uv, requiring an INTERNAL_ADDRESS for *arr connectivity and optional authentication via form login or HTTP Basic Auth. The project is actively maintained with regular releases.
