## What it is
SABnzbd is an open-source binary newsreader written in Python that automates Usenet downloads from NZB files, handling downloading, verification, repair, and extraction with no human interaction. It runs on Windows, macOS, Unix, and NAS devices, and is managed through a responsive web interface with API integration for tools like Sonarr and Radarr.

## Use cases
- download nzb files from usenet automatically
- self-hosted usenet downloader with web interface
- automatically verify repair and extract usenet downloads
- integrate usenet downloading with sonarr and radarr
- process rss feeds of nzb releases
- run a usenet downloader on a nas or docker

## When to choose
- you want fully automated, hands-off NZB downloading with repair and extraction
- you need a cross-platform downloader manageable from any browser or mobile app
- you want API integration with *arr media automation tools

## When to avoid
- you need a torrent or direct-download client rather than Usenet
- you don't have a paid Usenet provider account
- you want a lightweight GUI-only desktop newsreader without a web server
