How it works
From browser tab to TV in three steps
CastBrowser works inside the active Chrome tab. It looks for compatible video sources exposed by that page, updates the toolbar count, and shows the actions available for each detected video.
- 1
Open a normal website in Chrome and start the video you want to detect.
- 2
Select the CastBrowser icon to see compatible web videos found inside the active tab.
- 3
Choose Cast, Play, or Download when that action is available for the detected video.
Chrome extension limitations
A browser extension cannot access every video. Protected or DRM-encrypted streams, browser-restricted pages, subscription services, and videos hidden by a site's player may not be detected or available to play, download, or cast. The actions shown depend on what the current tab exposes. Only download media you own or have permission to save.
For the full CastBrowser experience—including the built-in browser and broader TV support—use the mobile app.
