NzbDAV¶

Mount NZBs as a virtual filesystem and stream directly from Usenet — without downloading full media files first.

NzbDAV is a WebDAV server that mounts NZB documents as a browsable virtual filesystem. Content streams on demand from your Usenet provider. A SABnzbd-compatible API lets Sonarr, Radarr, and similar tools use it as a drop-in download client — so you can build an effectively infinite media library without storing full files on disk.

Why NzbDAV¶

Virtual filesystem

Browse NZB contents instantly over WebDAV. No full download before you open a file.

WebDAV filesystem
Stream and seek

Jump anywhere in a video. Optional NNTP pipelining for higher throughput and faster seeks.

Streaming
*Arr compatible

SABnzbd API surface for Sonarr and Radarr, with symlink or STRM import strategies.

Infinite library
Multi-provider

Cascade routing, circuit breakers, data caps, and automatic failover across providers.

How NzbDAV compares¶

Choosing between streaming WebDAV tools and classic download clients depends on your media server, disk budget, and how much ops surface you want.

Quick start¶

Docker runDocker ComposeDUMB stack

docker run --rm -it -p 3000:3000 ghcr.io/nzbdav/nzbdav:latest

Ephemeral trial — settings are discarded when the container exits.

services:
  nzbdav:
    image: ghcr.io/nzbdav/nzbdav:latest
    container_name: nzbdav
    restart: unless-stopped
    ports:
      - "3000:3000"
    environment:
      PUID: "1000"
      PGID: "1000"
      TZ: Etc/UTC
    volumes:
      - ./config:/config

NzbDAV is a fully supported core module in Debrid Unlimited Media Bridge (DUMB). Enable NzbDAV during DUMB onboarding (or set Arr core_service to include nzbdav) for guided Usenet WebDAV + download-client wiring.

NzbDAV on dumbarr.com Hosting options

Then open http://localhost:3000 (self-hosted) or your DUMB service URL, create your admin account if needed, and configure a Usenet provider under Settings.

Expose carefully

Port 3000 is plain HTTP. Put NzbDAV behind HTTPS for remote access. WebDAV uses Basic auth, so TLS matters. Prefer binding 127.0.0.1:3000:3000 when a reverse proxy runs on the host.

Ecosystem¶

NzbDAV owns the streaming stack end to end. UsenetSharp, RapidYencSharp, and SharpCompress are developed in-tree under libs/; the native rapidyenc library remains a standalone submodule so connection, decode, and archive fixes land with the product.
