Open source alternative to nzb360
Last verified
Manage your self-hosted media stack from Android: Jellyfin, Radarr, Sonarr, Lidarr, Prowlarr, Seerr, NZBGet, and ntfy in one GPL-3.0 app.
Manages Jellyfin, Radarr, Sonarr, Lidarr, Prowlarr, Seerr, NZBGet, and ntfy from one app. The unified dashboard means a download failure, a stuck import, a new request, and a play session are all one app away.
You run Plex or Emby instead of Jellyfin, or only one or two *arr services. Sanctumd does not speak the Plex or Emby API, and the overhead of learning one more app is not worth it for minimal stack coverage.
GPL-3.0, no cost, deep Jellyfin admin screens, and a demo mode that requires no server to try. If nzb360's Jellyfin coverage or subscription price is the issue, Sanctumd covers more of the Jellyfin surface and costs nothing.
You are happy with nzb360's feature set and value the broader platform testing it receives across many user configurations. Sanctumd is built against one homelab; nzb360 has a wider install base that surfaces edge cases faster.
The TV-flavour APK installs alongside the phone app under a separate app ID and provides a Jellyfin streaming client using libmpv, which handles codec gaps that ExoPlayer leaves on cheap Android TV sticks. It supports Quick Connect sign-in, D-pad navigation, and direct output matched to the panel's refresh rate.
Your TV hardware is well-supported by the official Jellyfin TV client and you do not run into codec gaps. The TV APK is a streaming client only, with no dashboard or service management.
Running a self-hosted media stack typically means half a dozen separate apps on your phone. Radarr has its own mobile interface, Sonarr has another, NZBGet has one more, and Jellyfin's official client is a watch client, not an admin panel. When a download stalls, a request needs approval, or a library scan fails, you cycle through tabs and apps to find the problem and fix it, one service at a time.
The deeper friction is that most of these mobile interfaces are afterthoughts rather than first-class designs. Checking why a specific NZBGet download failed, editing a quality profile in Radarr, or approving a per-season Seerr request each opens a different app with a different navigation model. The result is that homelab management from a phone is slower and more error-prone than it needs to be, and anything beyond a basic status check typically ends up being done from a browser on a computer instead.
Manages Jellyfin, Radarr, Sonarr, Lidarr, Prowlarr, Seerr, NZBGet, and ntfy from a single Compose interface. Each service is added once with its address and API key or credentials; from then on you can approve a Seerr request, check an NZBGet queue, rename Radarr files, and start watching in Jellyfin without leaving the app.
Reaches into the admin layer for Jellyfin, covering users, per-library access, plugins, transcoding settings (with only touched fields sent), metadata and artwork editing, playlists, collections, API keys, backups, storage, timed lyrics, and instant mix. The companion Android TV APK uses libmpv for codec coverage that ExoPlayer misses, and installs alongside the phone app under a separate application ID.
First launch offers a demo of a busy fictional setup: films, shows, music, six viewers, downloads, requests, and push notifications, all answered inside the app with none of your own services touched. It stays available under Settings at any time. Every screenshot in the README comes from demo mode, so what you see is exactly what you get.
API keys and passwords are stored in the app's private storage, encrypted with AES-256-GCM. The key lives in the Android Keystore and cannot be read from a backup or a rooted-but-locked device. Nothing is sent anywhere except to the addresses you configured. No analytics, no crash reporting, no sign-up. A password-protected portable config export (PBKDF2 to AES-GCM) handles device migration.
Adds ntfy as a first-class service alongside the *arr stack. Direct topic subscription delivers instant local notifications, with per-server merging and a 12-hour message history. A fallback on-device polling worker covers new media, imports, and requests when push is unavailable. Tapping a notification opens the relevant title in the app.
Any URL you want to reach from the phone, added as a named button under a service, GET or POST with a JSON body, fired with two taps to prevent accidental presses. Shortcuts appear on their own screen, as a dashboard card, as a home-screen widget, and as a quick-action button.
nzb360 is the best-known paid Android client for the *arr stack and NZBGet, sold as a one-time purchase with paid major-version upgrades. Sanctumd covers most of the same service territory and adds a deeper Jellyfin admin surface.
| Feature | Sanctum Daemon | nzb360 |
|---|---|---|
| License | GPL-3.0 | Proprietary |
| Price | Free | Paid (one-time + upgrade fees) |
| Jellyfin admin | Full admin (transcoding, users, metadata, lyrics) | Watch client, limited admin |
| *arr stack | Radarr, Sonarr, Lidarr, Prowlarr, Seerr | Radarr, Sonarr, Lidarr, Prowlarr |
| NZBGet | Yes | Yes |
| ntfy | Yes (live push, topic browsing) | No |
| Android TV APK | Yes (libmpv Jellyfin client) | No |
| Demo mode | Yes (no server needed) | No |
| Tested configurations | One homelab setup | Broad user base |
Sanctumd is the better choice for people who already run Jellyfin and want admin depth beyond what nzb360 provides. It is also the right pick for Seerr users: nzb360 does not include a Seerr interface, while Sanctumd covers requests, issues, discover, watchlist, per-season requests, and where-to-stream in its Seerr screens. The GPL-3.0 license and no purchase price make the cost question straightforward.
nzb360 remains the better choice when breadth of tested configurations matters. nzb360 has a larger install base, which means edge cases and uncommon server versions surface and get documented faster. Sanctumd is built and tested against one homelab; if your setup deviates from the version list in the README, nzb360's wider testing history is a real advantage.
Install the phone APK by sideloading a signed release from GitHub (Android 8.0+, arm64).
```bash
adb install -r sanctumd-vX.Y.Z.apk
```No. Sanctumd speaks the Jellyfin API. Emby uses a similar API, so some screens may respond, but nothing is built or tested against Emby, and Plex is not supported at all. The tool is designed for Jellyfin and the *arr stack.
Download the signed APK from the latest GitHub Release and open it on the device, allowing installs from your browser or file manager when Android prompts. Obtainium can install it and keep it updated directly from those same releases. For sideloading from a computer, adb install -r sanctumd-vX.Y.Z.apk works.
No, and the README states there is no plan for one. Sanctumd is written in Kotlin with Jetpack Compose and targets Android only.
No backend, no analytics, no crash reporting, no sign-up. Requests go only to the addresses you configured. The one exception noted in the README: when Seerr screens are open, poster and cast images are loaded from TMDB's CDN, as that is where Seerr points for those assets. Nothing else reaches outside your network, and no other screen is affected.
Android 8.0 and above on arm64 hardware. The tested service versions are Jellyfin 12.1.0, Radarr 6.4.4.10685, Sonarr 4.0.20.3014, Lidarr 3.1.6.5078, Prowlarr 2.6.5.5623, Seerr 3.3.0, and NZBGet 26.3. Older major versions may work but are untested; the README lists what sees daily use.
