[GUIDE] Plembfin on Unraid: sync Plex, Emby, Jellyfin and Trakt

Hi everyone,

I have been building Plembfin, an AGPL-3.0 self-hosted tool for people running a media stack on Unraid who want Plex, Emby, Jellyfin, and Trakt to share watch state.

What it does

- Syncs watched and unwatched state across Plex, Emby, Jellyfin, and Trakt

- Keeps local watch history in SQLite

- Restores history when media is re-added or a server library is rebuilt

- Syncs resume positions across services

- Shows per-destination results and targeted retries in Sync Activity

- Includes Now Playing, ratings and watchlist options, and Seerr support

Install on Unraid

1. Add a Docker container using the image:

ghcr.io/lasikiewicz/plembfin:latest

2. Map /mnt/user/appdata/plembfin on the host to /data in the container.

3. Map host port 5055 to container port 5055.

4. Set ADMIN_USERNAME and a unique ADMIN_PASSWORD.

5. Start the container and open http://[UNRAID-IP]:5055.

6. Add the Plex, Emby, Jellyfin, Trakt, and optional Seerr connections in Settings, then run a first sync.

This is early testing, so please back up existing metadata before trying it. I would especially appreciate feedback from Unraid users on the container defaults, volume mapping, update behavior, and whether this should be packaged for Community Applications.

I am the author and am sharing it for testing and feedback. Issues and support: https://github.com/Lasikiewicz/plembfin/issues
