How to stream on Twitch and Rumble at the same time

Rumble's audience is different from Twitch's, and Rumble openly allows restreaming to other platforms, so going live on both from one OBS is an easy way to reach more people with the same stream.

Here are two ways to do it with Multistream: Multistream Cloud, where OBS uploads once and the cloud sends the stream to Twitch and Rumble, and the free Multistream app, where your PC sends both copies.

Method 1: Multistream Cloud (one upload for every platform)

Multistream Cloud takes one stream from OBS and sends a copy to Twitch and Rumble, and to up to 12 platforms in all. Your internet only uploads that one stream, so adding a platform doesn't need a faster connection. It comes with Pro, $10/mo.

  1. Create your Multistream account, then get Pro on your Account page.
  2. In the Studio, step 1 (Pick platforms), click Add a platform and add each one:
    • Twitch: click Sign in with Twitch, then Authorize in the Twitch window. Multistream reads your stream key for you.
    • Rumble: paste the Stream URL and stream key from Rumble's streamer configuration. Create a Static Stream Key in your Rumble account so it stays the same.
  3. Install Multistream for OBS (Windows 10 or 11, OBS 31 or newer) and open OBS. The Multistream dock opens on the right.
  4. In the dock, click Sign in with your browser and approve it.
  5. The dock's pre-flight check looks at your OBS settings, Multistream Cloud, your platforms and where OBS sends. If OBS isn't sending to Multistream yet, click Point OBS at Multistream.
  6. Click Go live on 2. After a 3, 2, 1 countdown, OBS starts streaming and Twitch and Rumble go live.

If OBS or your internet drops, Pro keeps your platforms live on your BRB clip for up to 30 minutes, and when OBS is back you carry on in the same broadcast, with the same chat. Turn it on under Disconnect protection.

Method 2: the free Multistream app (from your own PC)

The free Multistream app for Windows can send the copies from your own PC instead. Your upload then carries one copy for each platform, and if your PC's internet drops, your platforms drop with it. Run the app's Speed test first to see what your connection can carry, or work it out with the free upload calculator.

  1. Download the Multistream app for Windows 10 or 11 and open it.
  2. Go to Multistream → Go live and set Where the relay runs to This PC.
  3. Open Setup guide and click Add a platform for Twitch and Rumble. Twitch, YouTube and Kick accounts you've connected in the app add in a click; the others take their stream key.
  4. Install Multistream for OBS and open OBS. Without Pro, the Multistream dock sends your stream through the app on this PC, so keep the app open.
  5. Click Go live on 2 in the dock. Your PC uploads one copy for each platform.

Good to know for Twitch and Rumble

Make Rumble's stream key stay the same. Rumble gives each stream its own key (under Get the streamer configuration after you fill in the Go live form) unless you create a Static Stream Key in your Rumble account. A static key doesn't change, so you paste it into Multistream once. You can delete it any time to revoke it.

Rumble allows restreaming. Rumble says creators can stream to Rumble while restreaming to other platforms.

Twitch's simulcasting rules. Don't point Twitch viewers to your Rumble stream (in the title, links or chat commands), keep Twitch's stream at least as good as Rumble's, and don't show Rumble chat on your Twitch stream. Multistream's pre-stream check reminds you when Twitch is on your list.

One picture for both. Twitch and Rumble both show a 16:9 picture, so the stream OBS already sends works for both.

Questions, answered

Can you stream on Twitch and Rumble at the same time?

Yes. Rumble allows restreaming to other platforms, and Twitch allows simulcasting under its simulcast rules.

Where do I find my Rumble stream key?

Fill in Rumble's Go live form and click Get the streamer configuration: it shows the Stream URL and key. A Static Stream Key from your account settings stays the same between streams.

Does my Rumble stream key change?

Each stream gets its own key unless you create a Static Stream Key, which stays the same until you delete it.

Can I do Twitch and Rumble for free?

Yes, with the free Multistream app, which sends both copies from your PC, so your upload carries both. With Pro ($10/mo), Multistream Cloud takes one upload and sends both copies for you.
