Room for the video.

Choose a track. Find your scene. Let the controls step back.

Same frame. Same desktop. View full size

01.2 / TWO ENTRANCES

Two ways in.
One player.

A video on your Mac or a film on your server. Start where it lives. Both open in the same player, with the same familiar controls.

Open your file.

Press ⌘O, choose a video and watch. Your own clips, a saved film, an MKV in Downloads. No account or Jellyfin server needed.

Choose from your library.

Connect your Jellyfin server, browse your titles and press play. Your server’s library and watch progress, in an app that also opens local files.

Jellyfin needs an existing server and access to it. Local playback keeps its own history on your Mac; it does not sync a local file with a server copy.

01.3 / EVERYDAY CONTROLS

Settle in.

The everyday things, close at hand.

Your audio. Your subtitles.
Choose an available audio or subtitle track, or add an external subtitle file. Timing adjustments live in the track menus.
Your place, remembered.
Return to a recent local video where you left it, with your track choices. History stays on your Mac; clear it or turn it off in Settings.
A few familiar keys.
Space to pause. Arrow keys to seek. Keep your attention on the video, with the next action at your fingertips.

Built on Swiftfin.
With gratitude.

Swiftfin and its contributors built the native Apple Jellyfin client foundation that makes kurtz possible. kurtz is a fork of that work, adding local-file playback on Mac alongside the library experience.

kurtz is independent. It is not an official or endorsed Jellyfin or Swiftfin application.

Mobile and TV still need physical-device qualification and Apple review. Windows and Linux are not supported. Apple release plan

Beta limits, playback & building from source

Mac runtime checks were on Apple silicon. Intel, the oldest supported operating systems and long-session reliability still need qualification. Simulator builds do not establish device playback or Store approval.

VLC is the default local engine; mpv is the alternative. Format, HDR and audio behavior depend on the engine and file. The floating mini player is a kurtz window, separate from system Picture-in-Picture.

Your digital life. Actually yours. kurtz brings your films, photos and documents into one calm app that runs on your own hardware. It is in development. The video player stays free and complete on its own, with or without it.
