// In the room
Everything to watch as one.
A shared grid the whole room stays glued to, so the good part lands for everyone at the same second.
Synced playback
Play, pause or seek once and every friend’s video jumps to the same moment. Drift is corrected automatically, so you all stay together the whole way through.
Live reactions
Tap a heart or a laugh and it floats up on everyone’s screen at once. React to the big moment together, even when you are miles apart.
Vote what’s next
Cannot agree on the next video? The host opens a one-tap vote built from your grid, the room picks, and the winner starts playing for everyone.
Synced countdown
Hit Start together for a shared 3-2-1. Every screen presses play on the exact same beat, so the moment lands at once instead of scattered.
Host or shared control
Keep the remote to yourself, or switch to Everyone so any friend can play, pause and skip. Change your mind mid-party any time.
Free, no accounts
No sign-up, no install, nothing to download. Paste links, share the invite and watch. Nothing about what you play is tracked or saved.

// Matrix Browser
Want every stream on one screen?
The Matrix Browser is a split-view desktop browser where every tile is a real signed-in pane. Line up Netflix, Disney+, Max and your live streams side by side on one wall, with your own logins - one download, every screen at once, then throw the whole wall onto the TV.
Get the Matrix Browser ▸// From your couch
Pair your phone. Throw it on the TV.
Phone as the remote
Scan the QR on the wall and your phone pairs as a live remote - no app to install, it runs right in the browser. Mute all, paste in new streams, mix each stream's volume and shuffle the layout, all from the couch.
Cast to the big screen
Put the whole wall on the TV: one-tap Google Cast from Chrome or Android lands it on a Chromecast, and the Matrix Browser adds one-click “Open on my LG TV” for webOS sets. See every way to cast ▸

Frequently asked questions
- How do I host a watch party?
- Paste one or more YouTube or Twitch links on this page, choose who can control playback, and press Start watch party. You get a single invite link - send it to your friends, and everyone who opens it joins the same grid, playing in sync.
- Is it free?
- Yes. WatchMatrix watch parties are completely free, with no paid tier, no trial and no card required. There is nothing to install and no account to create. Paste your links, share the invite, and start watching together in a few seconds.
- Do my friends need an account?
- No. Nobody needs an account or an app. Your friends open the invite link in any modern browser and confirm a quick consent prompt to sync playback. The party runs entirely in the browser, and nothing about what you watch is saved.
- What can we watch together?
- Watch parties sync YouTube and Twitch videos and live streams, and you can mix several in one room. Other links such as Kick, Rumble or X are skipped, since only YouTube and Twitch can be kept in sync. Each person plays through the platform’s own official player.
- How do reactions and voting work?
- Tap an emoji and it floats up on every screen in the room at once. The host can also open a quick vote built from the current videos; the room picks, and the winner plays for everyone. A synced countdown starts every player on the same beat.
- Can everyone control playback?
- You choose. Host only keeps the remote with you; Everyone lets any guest play, pause and skip. You can switch modes at any point during the party, and the host always stays the source of truth so playback never loops or fights.
Grab your friends. Paste a link.
Two links and one invite is the whole setup. The room stays in sync from there.
