SABnzbd is an open-source, free, cross-platform newsreader and Usenet client. It enables users to download binary files from newsgroups, as well as search and manage their newsgroups, articles, and downloads. It supports several languages, including English, Dutch, German, French, and Spanish. SABnzbd can detect, repair, and extract files from a variety of archives, is fully automated, and integrates with popular Usenet search services. It also supports NZB files, which help to cut down on download time, as well as a web-based interface for remote access. It also offers a variety of options for optimizing download speeds and managing bandwidth. Furthermore, SABnzbd is compatible with various third-party applications, such as Sick Beard and Couch Potato, allowing for easy integration with other media centers.
The last discontinued version, 1.8, was released in April 2010, but can still be downloaded from SourceForge.
