Watch Multiple YouTube Videos at Once
Paste two or more YouTube links into the player and they run in one grid, in one tab. Nothing to install and no account to make. The free tier holds 4 videos at a time and Pro raises that to 32. Mute all but one and you can follow several channels without hunting through tabs.
How to set it up with YouTube
Open the player
Go to multivideo.io. There is nothing to download.
Paste a YouTube link
Copy the URL from the address bar or the Share button, drop it in the URL box, and press Add.
Add the rest
Repeat for each video. 4 fit on the free tier, 32 on Pro.
Pick a layout
Choose how many columns you want. Two columns suit two or four videos, three suit six.
Mute all but one
Each player carries its own audio. Silence the ones you are not listening to and leave one running.
Worth knowing
Private and age-restricted videos will not play
YouTube turns off embedding for private and unlisted uploads, and some music labels turn it off on their own videos. That setting belongs to the uploader, so no player can work around it. If a video plays on YouTube but refuses here, embedding is the reason.
Live streams and premieres behave like uploads
Paste the watch URL while the stream is running and it joins the grid the same way a finished video does.
