GridCast – Watch Multiple Tabs at Once

Watch videos from multiple tabs side by side in one grid. Perfect for following several games or streams at once.

Following more than one game, stream, or video at a time? GridCast puts them all on one screen. Click the GridCast icon on any tab that's playing video and it appears as a live tile in your grid. Add as many tabs as you like and the grid arranges itself automatically. JUST THE VIDEO, NOT THE WHOLE PAGE GridCast finds the playing video on each page, including videos inside embedded players, and crops each tile to it. Menus, sidebars, and ads stay out of the way. Prefer the whole tab? Press V to switch. ONE SOUND AT A TIME Every tile stays live, but only one plays audio. Press 1–9 to switch which one you hear, or M to mute everything. FOCUS MODE Double-click a tile (or press F) to make it big, with the others stacked alongside so you don't miss anything. PRIVATE BY DESIGN • Everything happens locally in your browser • Nothing is recorded, uploaded, or tracked • No accounts, no analytics, no ads HOW TO USE 1. Open a tab that's playing a video 2. Click the GridCast icon (pin it from the puzzle-piece menu) or press Alt+Shift+M 3. Repeat for each tab you want to watch KEYBOARD SHORTCUTS 1–9 · choose which tile you hear M · mute all F · enlarge the hovered tile (Esc to go back) C · fit or fill the tile V · video only or whole tab GOOD TO KNOW • Source tabs need to stay open, but they don't need to be visible. • Some protected (DRM) streams can show as a black tile, depending on your browser, operating system, and graphics hardware. That's a limitation of how those services protect their video, not something any extension can work around. • Tiles are sharper when the video is larger in its source tab. Theater mode helps.
