Consolidate Chat Sources for Use in OBS with Social Stream

5 min read
Hey! Thanks for stopping by! Just a word of warning, this post is about 2 years old, . If there's technical information in here it's more than likely out of date.

Do you ever watch a live stream and wonder how the chat is shown? If you have and you’ve searched online you’d probably have found videos detailing how to do this with services like Streamlabs, or Stream Elements. These involve configuring the panel you want in their service and copying a URL to use as a browser source in Open Broadcaster Software (OBS).

I’ve just found out about this awesome tool from Steve Seguin on GitHub called Social Stream. It’s a browser extension that allows you to consolidate chat sources from different platforms like YouTube, Twitch, Facebook and the like.

Who’s this for then?

If you use OBS and stream to more than one destination, like Twitch and YouTube using a service like Restream, then this is for you!

With services like this the chat can get fragmented sometimes between the platforms. Also if you have a chat overlay as a browser source in OBS you can typically only use one source in Streamlabs, or Stream Elements (either YouTube or Twitch). Meaning you’d have to have two chat panels.

Install the Social Stream extension

The Social Stream extension is available for download from GitHub, you can get the latest version from here. 👈 Clicking that link will download a .zip from GitHub.

Because the extension isn’t on the Chrome store, you’ll need to install it manually. The zip file will need to be extracted out into it’s own folder.

There’s a great guide on the GitHub repo explaining how to do this for Chrome.

I’m using Edge, so I’ll need to go to edge://extensions/ and toggle the ‘Developer mode’ option.


Then at the top of the page I can select the ‘Load unpacked’ option. This will open a file dialogue where I can select the folder for the extracted zip.


That’s the extension loaded now I can use it.

Using Social Stream extension

Now I’ve got the extension installed there’s a few options you get when clicking on it.


First I’ll need to ‘⚡Enable extension’ clicking that will change the background colour of the extension. Then I’ll check a couple of the options on there:

  • Hide source icon
  • Hide timestamp
  • Hide overlay after 20s
  • Auto-reply to “hi” messages
  • Filter out duplicate messages echoes


Notice that the URLs for the ‘Dockable streaming chat link’ and the ‘Single message overlay link’ have changed?

Those two link are what I’ll be using in OBS once I’ve got some live chats linked up to the extension.

Capture chat sources in Social Stream

Now to demo this I’m going to open a new tab in Edge and go find a YouTube channel that is ‘Live’ which has chat enabled.

In the top right of the chat panel I can select to pop out the chat, this is important as Social Stream wont capture the chat if it’s not popped out.

Now the chat is popped out I can click the ‘Dockable streaming chat’ link and the ‘Single message overlay’ link.

So in the ‘Dockable streaming chat’ tab I can see the live chat, if I click on one of the messages it will show in the ‘Single message overlay’ tab for 20 seconds.

Pretty neat right?

Ok, so no if I go to Twitch and find another streamer that’s on with a lot of chat I can do the same. In Twitch the option to pop out the chat is behind the cog on the bottom right of the panel.

Now on both YouTube and Twitch I can pause the videos on both as they’re not needed, it also helps save resources.

Add Social Stream to OBS

Now that I have Social Stream set up I can add it to OBS.

By the way, the chat sources should be from your own channels when doing this I’m using other peoples because I’m not streaming myself.

In OBS I’m going to create a new scene, call it ‘social-stream-chat’ then in the sources I can add a new browser source.


I’ll create a new source and call it ‘social-stream-single-message-overlay’ click ok, then the properties dialogue will show.


In here I can add in the URL for the chat source and the URL for the ‘Single message overlay link’ from the browser, I’ll add the dimensions of 1920 for the width and 200 for the height.

Now any time I select a chat message from the ‘Dockable streaming chat link’ tab it shows up in the OBS scene I created!

That’s awesome and all but you now have to manage a browser tab for your chat as well as OBS, well Steve has got you covered for that too because you can make a dock in OBS and control it there!!! 🤯

In OBS got to Docks in the menu then select ‘Custom Browser Docks’, in the dialogue I can add the new doc name, I’ll call it ‘Social Stream Chat’ and paste in the ‘Dockable streaming chat link’ tab URL. Click ‘Apply’ I now have a new dock where I can manage the chat from!

So configurable!

Say you don’t like how the overlay looks, you can change any part of it! Pop open the dev tools in the browser on either the ‘Dockable streaming chat link’ or the ‘Single message overlay link’ and you can inspect the css variables for each element you’d like to change.

You can find the CSS variables in the index.html file inside the extracted folder for Social Stream. Find the variable you want to change, change it then use that in the browser.

Example, instead of using the hosted version of the file, which is something like:

That would change to the local file location, so in the browser the above would look something like:



I’ve gone and added chat from two services together, YouTube and Twitch and added them to one panel in OBS.

That’s it! Well that’s all I’ve got to documenting right now, there’s a lot of other additional stuff you can manage in there yourself!

Steve did I great explainer video on using it as well you can check that out over on YouTube!

There's a reactions leaderboard you can check out too.
