NzbDav
WebDAV server that mounts NZB files as a virtual filesystem for streaming; provides a SABnzbd-compatible API and integrates with Sonarr/Radarr for media-server workflows.
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. (github.com)
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. (github.com)
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. (github.com)
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. (github.com)
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. (github.com)
