Install Jellyseerr on TrueNAS Scale

Jellyseerr is the media request manager for Jellyfin, Emby, and Plex — it lets users request movies and TV shows through a clean web UI, and the *arr stack handles the rest automatically.

What it is

Jellyseerr is the open-source fork of Overseerr, built for Jellyfin but also supporting Plex and Emby. Users browse or search for movies and TV shows, click "Request," and Jellyseerr communicates with Radarr/Sonarr to download and organize the content. The user gets a notification when the media is available.

It solves the "WhatsApp message" problem: instead of someone texting you "can you add this movie to Plex," they request it themselves through Jellyseerr, you approve it (or auto-approve), and the *arr stack handles the rest.

The hard part: connecting to Radarr/Sonarr and Jellyfin

The install is five minutes. The hard part is configuring the connections to Jellyfin, Radarr, and Sonarr so that requests flow through the entire pipeline without manual intervention.

The mistake everyone makes: using localhost as the hostname for Jellyfin, Radarr, or Sonarr. On TrueNAS Scale with Docker networking, localhost inside the Jellyseerr container points to Jellyseerr itself. Use the NAS IP.

How to install it

Docker Compose (TrueNAS Scale custom app)

services:
  jellyseerr:
    image: fallenbagel/jellyseerr:latest
    container_name: jellyseerr
    restart: unless-stopped
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    ports:
      - 5055:5055
    volumes:
      - /mnt/apps/jellyseerr/config:/config

After deploy:

# Open the web UI at http://<nas-ip>:5055
# First-time setup wizard guides you through connections

Initial configuration

1. Open Jellyseerr at http://<nas-ip>:5055
2. Sign in with your Jellyfin/Plex account (or create a local account)
3. Setup wizard runs:
4. Jellyfin URL: http://<nas-ip>:8096
5. Jellyfin API key: from Jellyfin → Settings → API Keys
6. Radarr URL: http://<nas-ip>:7878 + API key from Radarr → Settings → General
7. Sonarr URL: http://<nas-ip>:8989 + API key from Sonarr → Settings → General
8. Test connections → all three should return "Successfully connected"
9. Import libraries → Jellyseerr scans Jellyfin libraries to know what is already available

What I'd tell anyone building this

• Jellyseerr is the open-source alternative to Overseerr. Overseerr stopped active development; Jellyseerr is the maintained fork with Jellyfin support. If you run Jellyfin, use Jellyseerr. If you run Plex only, Overseerr still works but Jellyseerr is the better long-term choice.

• The API keys are mandatory. Jellyseerr cannot communicate with Radarr, Sonarr, or Jellyfin without valid API keys. If any connection fails, check that the API key matches what is in the target app's Settings → General.

• Auto-approve is useful but risky. For a personal server with one user, auto-approve saves time. For a shared server with multiple users, manual approval prevents someone from requesting 200 movies and filling your disk.

• Jellyseerr imports Jellyfin libraries to know what you already have. If a user requests a movie that is already in Jellyfin, Jellyseerr shows "Available" instead of "Request." This prevents duplicate downloads.

• The request queue is the bottleneck. If Radarr or Sonarr is not running, requests queue in Jellyseerr but do not download. Check that all three apps are running before enabling requests.

Quick install (Docker Compose):

services:
  jellyseerr:
    image: fallenbagel/jellyseerr:latest
    container_name: jellyseerr
    restart: unless-stopped
    environment:
      - PUID=1000
