Jellyfin suits people who want to run their own media server with nothing locked away, no account with a company and every feature included. Plex suits people who want a polished app with free movies, live TV and a media server they can set up quickly. If control and privacy come first, pick Jellyfin; if ease and extras come first, pick Plex.
Both let you turn a folder of films, shows and music into your own streaming service. They come at it from opposite ends. I read Jellyfin's site and documentation, Plex's plans and downloads pages, and the Plex App Store listing.

How Jellyfin works
Jellyfin calls itself the Free Software Media System. You run the server on your own computer or storage box, and it organises movies, shows, music, live TV recordings, books, comics and photos with artwork and seasons sorted for you. Its install guide covers Windows, macOS, Linux, Docker, Synology and TrueNAS SCALE.
Jellyfin's own documentation says it's an alternative to the proprietary Emby and Plex, and that there are no premium licences or features. The project relies entirely on volunteers and is licensed under the GNU GPL. Its home page is blunt about one thing: it doesn't run servers for users, so the setup and upkeep are yours.
How Plex works
Plex is two things in one. Its App Store listing describes a free app for finding films and shows, with over 50,000 free movies and shows and 600+ free live TV channels, plus a watchlist that pulls in services like Netflix and Prime Video. Then there's Plex Media Server, which scans your own files and streams them to your devices.
Plex's plans page lists a Remote Watch Pass for streaming your own media, or friends' and family's libraries, from anywhere, and Plex Pass for remote streaming for all users, hardware transcoding and downloads. Plex's listing also notes that some features are supported by interest-based advertising.
The remote watching difference
This is the detail that decides it for a lot of households. With Jellyfin, watching your own library away from home is part of the free software, with no premium tier on top. With Plex, the plans page puts streaming your personal media from anywhere behind the Remote Watch Pass or Plex Pass.
Plex's listing also says DRM-protected content, ISO disc images and video_ts folders aren't supported for personal media. If your collection includes ripped discs in those formats, check before you build your library around it.
Who each media server suits
Jellyfin suits people comfortable installing software, privacy-minded families and anyone who wants every feature without a company account. Plex suits people who want something that just works on the TV, families who'd enjoy free films and live channels, and anyone who wants their streaming services in one watchlist. If you like free, open software in general, my roundup of free open source screen recorders is another good place to start, and this guide to digital decluttering helps before you move a messy library onto a server.

My advice on Jellyfin or Plex
If you've never run a server, start with Plex: install Plex Media Server on the computer that holds your files and see how it feels on your TV. If you're happy tinkering, or you want remote watching without another plan, set up Jellyfin instead. Both can point at the same folders, so you can run them side by side for a week and keep whichever your family opens.
