jellyplex-sync
Bidirectional CLI sync tool that mirrors a movie library between Plex and Jellyfin using hardlinks.
jellyplex-sync is a command-line tool that keeps a movie library synchronized between Jellyfin's and Plex's differing directory formats, in either direction, using hardlinks instead of file copies to avoid extra storage use. It auto-detects the source layout, mirrors asset folders and loose files like posters and subtitles, and includes dry-run, diff, and plan modes to preview exactly what a sync would do before running it. It's aimed at self-hosters who run both Jellyfin and Plex, or are migrating from one to the other, and want a single source library to serve both.
Something wrong with this listing — dead link, not a real product, wrong info?
