Multi-Stream: Watch Twitch, YouTube, and Kick at Once
Want to watch your favorite streamer alongside the tournament feed, the speedrun world record attempt, and a podcast - all at once? Previews has a built-in Multi-Stream and Multi-Chat that works across Twitch, YouTube, Kick, and Facebook. Pick a built-in layout or save your own, send your whole view to a friend as one link, and read every chat in one window.
When one stream is not enough
Multi-Stream puts several live streams on one screen with chat for each, without opening a window per stream. It works across Twitch, YouTube and Kick, including mixing platforms in the same layout, which the platforms themselves cannot do.
There are evenings where one stream just is not enough. A tournament has multiple POV cameras and a main caster feed. Your favorite streamer is co-streaming with someone on a different platform. A speedrunner is going for a world record while a marathon runs in another tab. Tabbing back and forth, you miss the clutch moment in the one you were not looking at.
Sites like MultiTwitch and multistre.am exist for this, but they only handle Twitch, they kick you out of Twitch's own UI, and they forget your layout the moment you close the tab. Multi-Stream and Multi-Chat is the same idea built directly into Previews - cross-platform, cross-tab, and with saveable layouts.
How Multi-Stream works
A Multi-Stream button appears near the stream uptime on Twitch and Kick, and in the player area on YouTube. Click it to open the multi-view, then add channels by name. Each box is a real player with its own volume, quality and chat.
Once Multi-Stream is enabled, a small Multi-Stream button appears next to the stream uptime, under (or above) the video player on Twitch and Kick. On YouTube, the same button sits next to the like and dislike buttons under the stream. Click it and a fresh Multi-Stream tab opens with the current stream already loaded.
From there, add more streams the same way you would normally browse: click any channel in the sidebar, or use the top search bar and click the Multi-Stream button on a result. Each stream lands as its own box with its own chat - drag it by its top bar, resize it from any edge or corner (chat boxes too, to any shape), snap it to its neighbours, and minimize it when you want it out of the way.
Each box has its own controls: change the background color and transparency, change the chat font color, weight, and size, go fullscreen, or temporarily minimize a box without losing it. The page scrolls if you want more streams than fit on screen at once.
How do you watch multiple Twitch chats at once?
Every stream in a Multi-Stream layout keeps its own live chat next to its video, so you read all of them on one screen without a tab each. The chats are fully interactive, not read-only, so you can reply in any of them without leaving the layout.
This is the part the multi-stream websites tend to drop. They will tile the video well enough, but chat is usually either missing, read-only, or a single merged column where you cannot tell who is talking to whom. Keeping each chat attached to its own stream is what makes a tournament or a co-stream actually followable.
Can you see Twitch, YouTube and Kick chat in one place?
Yes. A single Multi-Stream layout can mix platforms, so a Twitch chat and a YouTube chat sit side by side in the same view, each attached to its own stream. That is not something the platforms allow on their own, and the multi-stream sites are almost all Twitch-only.
It matters most for simulcasters. A streamer going out on Twitch and YouTube at the same time has two separate audiences talking in two separate chats, and following both normally means two windows and a lot of alt-tabbing.
Each chat has its own appearance controls - font color, weight and size, plus background color and transparency - so you can shrink the ones you are only half-watching and keep the one you are actually talking in readable.
Where it works
On Twitch
The Multi-Stream button shows next to the stream uptime under the Twitch player, in the sidebar, and on search results. Clicking from any of those launches a new Multi-Stream Twitch tab with that stream preloaded - so you keep the full Twitch sidebar and search bar for adding more streams.
On YouTube
On YouTube live streams, the Multi-Stream button sits next to the like and dislike buttons under the player. Click it to open a Multi-Stream tab. From there you can add more YouTube streams from the sidebar - or mix in Twitch, Kick, and Facebook streams in the same layout.
On Kick
Kick gets the same uptime button under the player, with launch support from the sidebar and top search bar. Especially useful for viewers following streamers who simulcast across Kick + YouTube or Kick + Twitch - put the two side by side and never miss the version that has the more active chat.
And Facebook Gaming as a source
Multi-Stream itself runs on Twitch, YouTube, and Kick pages, but the stream boxes inside it support a fourth source: Facebook Gaming. Drop a Facebook stream into your layout the same way as any other - useful for esports broadcasts that have an official Facebook simulcast.
Layouts: pick one, save yours, share them
The Layouts menu is a visual gallery. Nine built-in arrangements - from Stream + Chat to a 3x2 grid - fill your screen with one click, and hovering any card previews it on the page before you apply it. Layouts are stored as proportions, so they scale with your window instead of being tied to one screen size.
Most people end up with two or three Multi-Stream layouts they reuse: a big tournament layout (lots of small boxes), a co-stream layout (two boxes), a chill background layout (one big stream + a small chat). Build the layout you want once, save it as a card - its thumbnail is a live miniature of the arrangement - and one click brings it back. Rename or delete a saved layout right from its card.
Every saved layout has a Share button, and so does the whole set. It gives you a link. Whoever opens it sees a preview of each layout inside, ticks the ones they want, and those land straight in their own Layouts menu - and your full settings (layouts included) can still be exported from the Previews settings panel.
How do you share a multi-stream layout with someone?
Press Share in the Multi-Stream bar and Previews gives you one short link. Whoever opens it sees a picture of the arrangement and which channels are in it, and one button rebuilds the whole thing on their screen - the same streams, the same chats, the same places.
This is the part that is genuinely awkward everywhere else. On a multi-stream site you send a URL with the channel names in it and your friend gets four boxes in a row, not the arrangement you spent the evening building. A Previews link carries the arrangement itself: which stream is the big one, where each chat sits, what you had minimized, and which platform every box came from.
Your friend does not need the extension to click it. Without Previews the link opens a page showing what is inside - the layout, the channels - and where to get it. With Previews installed, the page turns into an Open button instead. Links work for 30 days, and both the sender and the receiver are told so.
Layouts travel the same way, on their own: share one, or the whole set at once, and the person opening the link picks which ones to add to their own Layouts menu.
Multi-Stream + every other Previews feature
There is a companion setting called Advanced Video Embeds that pulls all of your other Previews features into every embedded stream inside Multi-Stream. With it on, each box in your layout gets:
- FlashBang Defender - dim a single box at 2 AM without dimming the others.
- Auto-Refresh on player errors - one box crashing on a #2000 will not take down your tournament layout.
- Picture-in-Picture - pop one box into a floating window while you keep the rest in the layout.
- Fast-Forward to live, plus arrow-key seeking switched to 1.5 second steps so you can sync streams precisely.
- Stream screenshot, fullscreen-with-custom-chat, and the rest of your enabled Previews features.
If Sidebar Favorites is on, your favorites are right there in the sidebar of the Multi-Stream tab for fast adding. And if Auto Channel Points is enabled, every stream in your layout keeps collecting points in its own chat box.
How to enable it
- Install Previews from the Chrome Web Store, Firefox Add-ons, or Edge Add-ons.
- Click the Previews icon in your browser's toolbar.
- In the settings panel, find Multi-Stream & Multi-Chat. It is enabled by default.
- While you are there, also enable Advanced Video Embeds right below it - that is what brings the rest of your features into each stream box.
- Refresh any open Twitch, YouTube, or Kick tab.
- Look for the new Multi-Stream button next to the stream uptime (Twitch/Kick) or next to the like/dislike buttons (YouTube). Click it to launch your first layout.
What else Previews can do for you
Multi-Stream pairs well with the rest of the Previews toolkit. If you watch streams seriously, you will probably also want:
- Picture-in-Picture - pop a stream out into a floating window so you can keep watching while you work.
- Fast-Forward - jump back to the live edge with one click when a stream is delayed.
- Sidebar Favorites - pin your top streamers to the top of the sidebar for fast layout building.
- Auto Channel Points Clicker - collects bonus channel points on every Twitch stream in your layout in parallel, even while the tabs sit in the background.
- Auto-Refresh on Twitch Errors - automatic recovery from #1000, #2000, #3000, #4000, and #5000.
- FlashBang Defender - dim the player when streamers blast a white screen at 2 AM.
- Plus live hover previews, voice typing in chat, predictions sniper, clip downloader, and more.
Frequently asked questions
Can I watch multiple Twitch streams at the same time?
Yes. Previews has a built-in Multi-Stream and Multi-Chat. Click the Multi-Stream button next to the stream uptime, and a new tab opens with that stream loaded. Add more streams from the sidebar or the top search bar - each one lands in its own draggable, resizable box with its own chat alongside.
Can I watch a Twitch stream and a YouTube stream at the same time?
Yes. Multi-Stream supports cross-platform layouts: Twitch, YouTube, Kick, and Facebook streams in any combination. Mix a Twitch tournament with a YouTube co-streamer reacting and an official Kick simulcast - all in one window with every chat.
How do I save a Multi-Stream layout?
Once you have arranged your stream boxes the way you want, save it as a layout preset from the Multi-Stream toolbar. Build different presets for different use cases - a big tournament layout, a two-stream chill layout - and switch between them with one click. Presets are also importable and exportable from the Previews settings panel.
Is this a MultiTwitch or multistre.am alternative?
It does the same job and more. MultiTwitch and multistre.am only handle Twitch, kick you out of the Twitch UI, and forget your layout when you close the tab. Previews keeps everything inside your normal Twitch, YouTube, or Kick workflow, supports cross-platform mixing including Facebook, and saves your layouts as reusable presets.
How does Multi-Chat work? Can I reply in every chat from one box?
Multi-Chat shows a chat box for each stream in your layout, side by side. You read all chats in one window and reply directly in whichever box you want. Each box is individually customizable - background color, transparency, font color, weight, size, and fullscreen - so you can lay them out however reads best.
Does Multi-Stream work on Kick?
Yes. The Multi-Stream button shows up under the Kick player the same way it does on Twitch and YouTube. You can launch a Multi-Stream layout from a Kick page, a YouTube page, or a Twitch page - and from there add streams from any platform Previews supports, including Facebook.
Will my saved Multi-Stream layout look right on a different monitor?
Layout presets are tied to your browser window size at the time you saved them. Loading a preset on a different-sized window or monitor still works, but the boxes may end up sized differently than you remember. The simplest fix is to save a separate preset for each setup you regularly use - laptop, ultrawide, second monitor.
