NzbDav

NzbDav is a WebDAV server that exposes NZB documents as a browsable virtual filesystem and streams their contents directly from Usenet without requiring full local downloads. It presents a SABnzbd-compatible API so automation tools like Sonarr and Radarr can use it as a drop-in download client.

Key Features

• WebDAV server that exposes a virtual, streamable filesystem over HTTP(S).
• Mount and browse NZB documents without downloading payloads.
• Full streaming and seek support for video; can stream files inside RAR/7z archives and password-protected archives.
• SABnzbd-compatible API for integration with Sonarr, Radarr and similar automation tools.
• Healthchecks and automatic repair/replace for missing Usenet content.
• Official Docker image for containerized deployment.

Feature details and examples are documented in the project README.

Use Cases

• Provide an "infinite" Plex/Jellyfin/Emby library by streaming media directly from Usenet without local storage.
• Use NzbDav as a drop-in SABnzbd-compatible download client for Radarr/Sonarr automation workflows.
• Mount Usenet-sourced content via rclone (WebDAV) so media servers and players access streams via a filesystem mount.

These workflows are commonly described in the project documentation and community posts.

Limitations and Considerations

• Requires accompanying tooling to mount and expose streams (examples and recommended settings use rclone with a FUSE driver); some rclone flags (e.g., --links) are required for expected behavior — check the README for exact guidance.
• Playback and client compatibility can vary: community reports describe occasional player errors (client-specific), mount/configuration sensitivity, and the need for correct reverse-proxy/HTTPS setups for some clients.
• Performance and reliability depend heavily on the Usenet provider and indexer behavior; large-scale automated searches can trigger high API/indexer usage.

These constraints are noted in the documentation and in community discussions.

NzbDav is a developer-focused tool for integrating Usenet streaming into media-server ecosystems, optimized for containerized deployment and automation via SABnzbd-compatible APIs. It is primarily distributed via its source repository and official Docker images; deployers should review rclone/FUSE and client compatibility notes before production use.
