Streaming LAN Cast door Fabrizio Santi

Streaming LAN Cast sends the video playing in your current Firefox tab to a smart TV, AV receiver, or media player on your own network, over DLNA/UPnP or Google Cast (Chromecast, Android TV, Google TV). It works with live streams and with on-demand video, and on-demand video stays seekable on the TV so you can skip around with the remote.

Private by design: everything runs on your own machine and local network. No data about what you watch is sent to any server, no tracking, no analytics, no account.

How it works: a small companion helper (open-source, you run it yourself) does the actual casting. The extension finds the devices on your network, lets you pick one, and tells the helper what to cast. It only ever talks to the helper on your loopback address (127.0.0.1).

You install the helper once (Windows, macOS, Linux): https://fabriziosantidev.github.io/streaming-lan-cast/

Features:
- Cast the current tab to DLNA/UPnP or Google Cast devices
- Live streams and on-demand video, seekable on the TV
- Choose the quality, and change it while casting
- Optional source detection for sites that need it (off by default)
- Available in 10 languages
