Plembfin is a local-first watch-state hub for Plex, Emby, Jellyfin and Trakt. Keep watched history, resume progress and rewatches canonical in SQLite, then sync each destination with an explainable activity ledger, targeted retries, backups and a private dashboard. Self-host it with Docker Compose and see every delivery reason instead of trusting a single sync status. Website: https://plembfin.com
