Native macOS app for Jellyfin metadata

File your media like you mean it.

The missing step between a messy downloads folder and a beautiful Jellyfin library. Drop in release-named files and Showrunner identifies each title, renames it to Jellyfin's exact conventions, and stages the artwork. Nothing touches your disk until you press Start.

Drop messy release-named video files on the app. Showrunner parses the names, finds the right titles, and files everything into your Jellyfin library; tidy title folders, season folders, episode names, even your subtitles.

How it works

Three steps from chaos to catalogued

No setup. Drop, glance, done.

1

Drop

Drag your release-named video files onto Showrunner. It parses the messy filenames and finds the right titles on TheMovieDatabase.

2

Review

See the whole queue at a glance; each matched title, the exact Jellyfin path it will become, and the staged poster, backdrop and logo. Fix any metadata match or swap art in a click.

3

Process All

Hit the button. Showrunner renames, stages the artwork, and files everything into your library - folders, seasons and all. Nothing before then.

Features

Everything in its right place

Built around one job: getting your library exactly the way Jellyfin deserves it.

Movies & TV, sorted

Films and shows both. Episodes get proper season folders and episode titles pulled from TMDB — multi-episode files and specials handled too.

Jellyfin-perfect naming

Tidy “Title (Year)” folders, season folders and episode names, all matching Jellyfin's conventions exactly, with optional tags for unambiguous matching.

Artwork, staged for you

Every title gets its poster, backdrop and logo; plus series and season posters for TV. Pick an alternative, or drag your own art straight from Finder.

Subtitles ride along

Your .srt, .ass and other sidecar files move with their video automatically, language suffixes preserved.

Safe by default

Nothing touches your disk until you press Start. Existing series folders are used correctly and new seasons slot in. Nothing is ever overwritten.

Native & private

Built for Mac. Sandboxed, and it sends only search queries to find your titles. Showrunner collects nothing about you.

FAQ

Good to know

Will it mess up my files?
No. Showrunner shows you the full plan first and changes nothing until you press Process All. It merges into existing folders and never overwrites anything.
Does it handle both movies and TV shows?
Both. Episodes get proper season folders and titles, and it handles multi-episode files, specials, and subtitle sidecars along the way.
Where do the names and artwork come from?
From TheMovieDatabase (TMDB). Each title defaults to its main poster, backdrop and logo, and you can swap in any alternative — or drag your own image from Finder onto any artwork card.
Does Showrunner collect my data?
No. It sends search queries derived from your filenames to TMDB so it can find matches, and collects nothing about you. See the Privacy page for details.
