Streaming LAN Cast door Fabrizio Santi

Streaming LAN Cast sends the live 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).

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
- Adjustable quality and buffer (latency vs. stability)
- Optional source detection for sites that need it (off by default)
- Available in 10 languages
