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.

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 Community chat: https://discord.gg/7ZmEGKcRC5 Thanks
