YouTube Multi-Stream by Submitune

A small, free web page that shows one YouTube video in many embedded players at the same time, arranged in a grid. Everything runs inside this one page using YouTube’s official embedded player — no downloads, no pop-ups, no new tabs, and no account needed.

1. Copy a video link from YouTube (from the address bar or the Share button).
2. Paste it in the YouTube video URL box.
3. Type how many players you want, from 1 to 1000.
4. Click Start Streaming. Players are added in batches of 10 so your browser stays responsive.
5. Use Back to return here (players keep running), or Stop All to remove every player.

Players start muted (browsers only allow muted autoplay). Click the speaker icon on any player to unmute it. Your session is saved, so refreshing the page brings the players back until you press Stop All.

• Build a video wall for a screen, event, shop window or classroom.
• Check how a video looks at different tile sizes and on different devices.
• Test how much embedded video your computer or phone can handle.

Note: this page does not increase a video’s view count. YouTube filters repeated, muted or automated plays, and the players here are ordinary embeds.

YouTube Multi-Stream is made by Submitune Stream, the team behind Submitune. It’s built as a lightweight single-page tool in plain HTML, CSS and JavaScript, so it loads fast and works on any modern browser. Videos remain the property of their creators and are shown through YouTube’s official embed player.

It depends on your CPU, memory and internet speed. Most laptops handle 10–30 players comfortably; beyond that, video may stutter and the page can slow down. You’ll see a warning before starting if your number is above the suggested limit for this device.
