A summary, not legal advice.
WHY IT MATTERS
Windows and macOS cast to a TV out of the box; on Linux a working option is hard to find. The author says they built it after nothing worked for watching movies from a Linux laptop on the TV.
BUILD FROM THIS
- Casts over Miracast (WFD), DLNA or Chromecast. The tray app follows the system language, and on KDE/GNOME Wayland it captures the screen through the desktop's screen-share dialog (xdg-desktop-portal).
WHO IT'S FOR
- Linux laptop users who want to watch video or show a presentation on a TV.

# Follow the install guide in the docs at fluxcast.dev, then pick your TV from the tray.CAVEATS
- Per the README, only WFD (Miracast) is validated as release-ready; DLNA is a fallback, and Cast is experimental and did not work on the tested Samsung TV. It is tuned for wlroots-class setups such as Hyprland.
