Dive into your media
An all-in-one desktop client for Jellyfin. Your media, your server, Seerr requests, and YouTube, without leaving the app.
Fathom brings your whole Jellyfin setup into one window: movies, shows, music, and Live TV, plus most of Jellyfin's server-side management, so you rarely need the web dashboard. Two optional integrations, Seerr requests and a full YouTube client, live right inside the app. Everything plays through mpv (via media_kit / libmpv), so you get direct play, hardware decoding, and real subtitle and audio track control.
- One player for everything. Jellyfin and YouTube share the same control bar, seek bar, speed control, track pickers, and keyboard shortcuts, plus a Playback Info overlay that shows codecs, resolution, and the live hardware-decode path.
- Run your server from the app: users, libraries, scheduled tasks, transcoding, Live TV and DVR, and more, without the web dashboard.
- YouTube, built in (optional): search, subscriptions, local playlists, SponsorBlock, DeArrow, downloads, theater mode. No account, no ads.
- Requests and ratings: Seerr browse-and-request with manage-in-place, plus Rotten Tomatoes, IMDb, and more.
- Internet radio with live time-shift, casting, watch together over SyncPlay, picture-in-picture, and light / dark / AMOLED themes.

Fathom is free and open source, and always will be. It's built and maintained by one person; donations help cover real costs like Mac hardware for macOS and iOS builds. Starring the repo helps too, and costs nothing.
