Plex turns a folder of movies and shows into something that looks like a streaming service: it scans your files, fetches posters and metadata, transcodes on the fly, and streams to a TV, phone, or browser anywhere. As a way to enjoy a media collection it is polished and genuinely pleasant. The catch is that this polish increasingly routes through Plex's own account and cloud. Sign-in goes through Plex's servers, and the features that make it shine - hardware transcoding, mobile sync, multiple users - sit behind a Plex Pass subscription, which puts a paid middleman between you and your own files.
The open source alternative below offers the same media-server experience - automatic library scanning, artwork and metadata, transcoding, and apps for the usual devices - with no account in the middle. It runs entirely on hardware you own, your library never checks in with a vendor's cloud, and watching your own collection costs nothing beyond the server it lives on.
