Download SABnzbd
SABnzbd is a Usenet client that turns NZB files into finished files without manual steps. It downloads articles from multiple servers, verifies the data, repairs missing parts, extracts archives, and applies cleanup rules. A browser interface and an HTTP API give control over the queue, history, categories, and speed limits. Post-processing scripts connect the downloader to other tools in a media or data workflow.
The application targets users who retrieve large files from Usenet and want the verification and extraction stages handled automatically. It runs on Windows, macOS, and Linux, and can be controlled from another device through the web panel. Scheduling, bandwidth limits, RSS filtering, and notification services cover routine operation. Configuration is stored locally, and the API allows integration with automation software.
SABnzbd is maintained by The SABnzbd-Team and distributed as a cross-platform binary newsreader. The program supports parallel downloads, server priorities, PAR2 repair, archive extraction, and job categories. Its interface is available in a browser, and the API accepts commands from external applications. Security updates and bug fixes are published on a regular schedule, with upgrade paths documented for older installations.
