NzbDAV

NzbDav is a WebDAV server that allows you to mount and browse NZB documents as a virtual file system without downloading the underlying payload upfront.

It's designed to integrate with other media management tools, like Sonarr and Radarr, by providing a SABnzbd-compatible API that those applications already understand.

NzbDav does not provide media. It simply exposes the catalog exposed by your Usenet provider so that legitimate backups or time-shifted recordings can stream into Plex, Emby, Jellyfin, or similar players. You must ensure that every source you connect is authorized in your jurisdiction and complies with our Acceptable Use Policy.

How do I access NzbDAV?

NzbDAV is available:

• From your dashboard: https://your-username.elfhosted.com
• Directly: https://your-username-nzbdav.elfhosted.com

How do I use it?

Signing in

NzbDAV's web interface sits behind your ElfHosted login, and the app's own login screen is switched off. There's no separate NzbDAV password to set, change or recover: if you can reach your ElfHosted dashboard, you can open NzbDAV.

Stremio

Using NzbDAV with Stremio is a simple process, and the ElfHosted defaults are designed to work once you configure it with sources you have the rights to access. Here's a video guide:

Arrs

Building a large streaming library with Arrs requires a few extra toggles compared to AIOStreams + Stremio. Here's a demo for Plex, followed by a summary of what you need to set (these are defined on fresh NzbDAV installs)

In Radarr/Sonarr..

Configure a "SABNZBD" downloader in Radarr/Sonarr, pointing to nzbdav port 3000 (no SSL), using categories which match their names (Radarr=radarr, Radarr4k=radarr4k, etc).

Paste in the SABNZBD API key from NzbDAV, and test.

In NzbDAV..

Usenet

Configure your own Usenet provider that authorizes your usage, Connections Per Stream can be adjusted, start with 8 and increase to suit your requirements.

Using more than one provider (primary and backup): NzbDAV can hold several Usenet providers and use them in priority order. In Settings -> Usenet, click Add for each one, fill in its Host, Port, Security (SSL), Username, Password and Max Connections, then choose its Behavior:

• Pool Connections (the default) is a primary provider. NzbDAV loads from all your "Pool Connections" providers together, and their Max Connections add up.
• Backup Only is a fallback provider. NzbDAV only reaches for it when your pooled providers can't supply part of a download, so a cheap block account on a different backbone fills the gaps without eating into your main plan.
• Disabled keeps a provider on file without using it.

There's no separate "primary" switch: every Pool Connections provider is a primary, and every Backup Only provider is a fallback. To change a provider's role later, Edit it and pick a different Behavior. NzbDAV tests each provider's connection before it will let you save.

SABnzbd

• Categories: radarr,radarr4k,sonarr,sonarr4k,sonarranime
• Rclone Mount Directory: /storage/nzbdav CRITICAL

WebDAV

It doesn't matter what you set here, because WebDAV auth is disabled in our environment (since it's never exposed externally). Apps that ask for a WebDAV username and password, like UsenetStreamer, are given placeholder values for the same reason.

Radarr/Sonarr

Add all your Arrs, using the API keys found in each Arr under Settings -> General. Refer to this guide to confirm the hostnames and ports per-arr.

Automatic queue management - tune these to your preferences, depending on whether you want lots of manual intervention / twiddling, or set-and-forget.

Repairs

• Enable Background Repairs: Optional (but you need Library Directory below to enable it)
• Library Directory: /storage/symlinks

External access (exposing)

To make NzbDav's SabNZBD API work with 3^rd-party apps, you'll need to "expose" its API, so that it can be accessed without ElfHosted SSO.

1. Refresh your SabNZBD API token in NzbDAV
2. Get this product from the store, to bypass SSO for the API endpoints

Note that exposing NzbDAV doesn't make the content or the admin UI publicly available - it's simply about exposing the SabNZBD API endpoints so that they're accessible from external tools.

Opting out of the shared release-health index (optional)

Your NzbDAV checks candidate releases against a shared release-health index before offering them, which is how dead and incomplete posts get filtered out before you try to play them. The index is built from the NZBs that participating instances contribute, so every instance both reads it and adds to it.

Contributing sends the NZB document itself: the article IDs, group and file names that make up a post. It does not send anything about you, your account or what you watch.

If you would rather not contribute, use ElfBot to set:

ZYCLOPS_INGEST=false

Reading the index and contributing to it are one setting, not two, so opting out also stops your instance using it: your indexers are no longer health-filtered, and search results will include dead posts that would otherwise have been dropped. Set it back to true (or remove it) to rejoin.

Calling an indexer directly (optional)

NzbDAV's requests to your Usenet indexers go through a shared forwarding service rather than straight out of your instance. Some indexers would rather see the request arrive from your instance itself, and will tell you if it matters to them.

REPLAY_BYPASS_HOSTS lists the indexer hosts to call directly. Anything not listed keeps going through the forwarding service, so this is a per-indexer choice rather than an on/off switch. Use ElfBot to set it:

REPLAY_BYPASS_HOSTS=your-indexer.example,*.your-indexer.example

Each entry can be written three ways:

Separate entries with commas, semicolons, spaces or newlines, in whatever mix you end up with. There is no catch-all: a bare * is ignored on purpose, because bypassing every indexer at once is not a choice anyone makes deliberately.

This is a different setting from the shared release-health index above. This one only changes how a request reaches an indexer; it does not change whether your instance takes part in the shared index.

NzbDAV also works with

• Lidarr

• Mylar

• AIOStreams

• Prowlarr

• Radarr

• Readarr

• Sonarr

What users say..

We're rocking some excellent TrustPilot Reviews, and here's what some of our usersfriends say..

I am new here, but today I learned realized that Elfhosted is one of the best free and open source software communities I've seen, and FOSS communities have been at the center of my life since the 90s (Perl, PHP, Symfony, Drupal, Ethereum, etc.). Great open software built by great people who care = great community, and that is something special.

You've done an amazing job @Funky Penguelf with the platform you provide and this place has an awesome mix of active community caretakers and software creators that I've seen here so far like BSM, Spoked, LayeZee and other elf vengers. Keep up the energy, productivity and community and take time to enjoy it and appreciate each other!

As a happy Elfhosted customer—who also self hosts MANY things across about 10 severs (dedicated, VPSes, and VMs running on Synology), I wouldn’t switch to self hosting the services I get from Elfhosted. They just work with very little effort configuring things, and the support the owner and his team provides is second to none. Plus I love being part of a fledgling—but quickly growing—enterprise.

I’ve been using this service for a while now, and honestly, it’s a game-changer compared to anything else I’ve tried for managing my media library. The support is fantastic—super quick, and if the staff aren’t around (which rarely happens), the community steps up right away. I can’t imagine going back to any other platform.

Before this, I had my own setup with a NUC, NAS, and tools like Sonarr and Radarr. It worked pretty well for a while, and my internet speed was high enough to stream without any buffering. But in the end, it wasn’t worth the time or headache of managing all the storage and keeping everything running smoothly.

Now, with this service, everything runs smoothly in 1080p+ with no buffering issues. The interface is really easy to use, which makes managing everything a breeze. Plus, having a whole community of smart people available for guidance is a huge bonus.

I was sold from the start, which is why I quickly upgraded from a 1-month to a 3-month subscription, and I’m planning to switch to a 1-year plan soon. This service totally pays for itself, and I’m sure you won’t be disappointed. It’s been really impressive.

Best possible options for anyone looking for the do-it-all option along with the best customer service ive experienced in this space so far. Id rate it a 6 if I could but its limited to 5/5...

(responding to a discussion re the cost of ElfHosted vs mainstream streaming / self-hosting):

I didn't know that the goal of this project was to compete with large companies running/renting entire DCs. I was under the impression that the goal of this project was to manage the updating of almost selfhosted applications on a shared platform with other users. Basically, be my sysadmin for me.

That being said, paying for services is the 'easy button'. There is a real world cost incurred for the time saved. Time is money. Time is the most valuable currency that exists. Once time is spent, it's forever lost, one cannot retrieve it again (yet). In my mind, there are 3 options for use of time with respect to: mainstream, selfhosting, elfhosted.

• mainstream - my time is valuable and I don't want curated content and I don't care what content that I have the ability to consume. I only like what's popular.

• elfhosted - my time is valuable, I want my own curated content without being forced to browse past the same damn entry 500 times just to find out that I can't watch the movie I want because it's not available in my current location or was removed last week from mainstream providers.

• selfhost - I care about costs and I have nothing but time to waste or I want to learn about the backend of the systems involved. I'll pay for my own VPS/homelab, electricity, manage the OS, manage app updates, figure out how to make the apps talk nice to each other, create my own beautiful frontend.

I know how much my time is worth, does that reddit poster know how much their time is worth? Without knowing what you are worth, you can't make effective capital expenditures with respect to the time it will take to recoup the capital.

I know I don't need elfhosted at all for my use case. I choose to stay with elfhosted because it's my 'easy button'. It's an efficient capital expense for the amount of time it saves me managing my own hardware, apps and saves me electricity costs. I'm also in a situation where I don't have upload bandwidth from my home to serve HD content to myself remotely. If I lived back in a city, I would still be here. My time is worth $$/hr.
