How to Multistream to Twitch and YouTube in 2026

Multistreaming, going live to Twitch and YouTube at the same time, is allowed and easy in 2026. Twitch dropped its old simulcast restriction in October 2023, so Affiliates and Partners can broadcast to both platforms at once, and there are three common ways to set it up: a cloud restreaming service like Restream, a local OBS plugin, or a browser studio like StreamYard. The setup is the easy part. The harder question, and the one most tutorials skip, is whether you should: for a small channel, splitting a thin live audience across two rooms can make both feel emptier, and a lower-friction version of "both" (stream on one platform, post clips to the other) often grows you faster. This guide covers the methods and the honest trade-off.

This is the practical companion to the strategic question of which platform to build on; read that one for the choice, this one for the how.

Is multistreaming to Twitch and YouTube allowed?

Yes, and this is the part many older guides get wrong. Twitch used to restrict simulcasting through its exclusivity terms, which made streaming live to Twitch and YouTube at the same time a gray area. That changed in October 2023, when Twitch updated its simulcasting guidelines to allow broadcasting to other platforms at the same time.

So in 2026 you can simulcast to Twitch and YouTube without breaking Twitch's rules. A couple of finer points: the permission applies to Affiliates and Partners under the simulcasting guidelines, and Twitch has also stopped penalizing combined chat (showing both platforms' chats together), though its formal guidelines documentation has lagged behind the actual enforcement on that detail. The headline is simple: simulcasting is permitted now, where it once wasn't.

The three ways to multistream

There are three common setups, and they trade off between load on your machine and convenience.

Cloud restreaming (Restream and similar)

A cloud restreaming service takes your single stream and rebroadcasts it to multiple platforms from their servers, not your computer. You send one stream to Restream, and Restream sends it to Twitch and YouTube. Restream offers a free tier that covers dual-streaming to Twitch and YouTube. The big advantage is that it doesn't add load to your setup: your PC sends one stream, and the cloud handles the fan-out, so your CPU and upload bandwidth only carry a single broadcast.

OBS with the multi-RTMP plugin

The obs-multi-rtmp plugin adds extra RTMP outputs to OBS, so your local machine sends a separate stream to each platform directly. It's the cleanest fully-local option and keeps everything on your own software with independent settings per platform. The cost is on your hardware: each additional platform is another full stream your CPU encodes and your connection uploads, so multi-RTMP needs more processing power and more upload bandwidth than the cloud approach.

Browser studio tools (StreamYard and similar)

A browser-based studio like StreamYard lets you run a show in your browser and add both Twitch and YouTube as destinations in one place, usually on a paid plan. It's the simplest for talk-show or webcam-forward content and people who don't want to manage OBS, at the cost of less control than a full local setup.

The rough rule: cloud restreaming if you want to spare your machine and keep setup simple, OBS multi-RTMP if you want full local control and have the bandwidth and CPU headroom, browser studio if you want the least technical setup.

What multistreaming costs your setup

Before you pick a method, know what simulcasting actually demands, because the requirements scale with each platform you add.

Every live destination is a full video stream your system has to produce. With a local setup like the OBS plugin, your computer encodes and uploads a separate broadcast for each platform at once, so two destinations roughly double the upload bandwidth and add real CPU load. A 1080p60 stream commonly wants somewhere around 6 Mbps of upload on its own, so sending two locally wants close to double that, and a connection near its ceiling will start dropping frames. Cloud restreaming sidesteps this: your machine sends one stream to the service and the service makes the copies, so your local cost stays flat no matter how many platforms you add. If your upload or CPU is anywhere near its limit on a single stream, that difference picks your method for you.

The catch for small streamers

Here's the part the tool tutorials leave out. Multistreaming widens your live reach, but it splits your community, and for a small channel that split can cost more than the reach gains.

A stream's energy comes from chat. When 8 viewers are all in one Twitch chat, the room feels alive and people interact. Split those same 8 across a Twitch chat and a YouTube chat and each room feels half-dead, which hurts the retention that, as covered in how to grow on Twitch, actually grows a channel. Combined-chat tools help, but they don't fully solve the feeling of a fragmented audience. For a streamer whose main constraint is making the room feel active enough to keep new arrivals, simulcasting can work against the goal. This is why the reach-versus-community trade-off matters more the smaller you are: the reach is marginal at small numbers, and the community cost is real. A thin community split in two is thinner still.

The lower-friction version of "both"

There's a way to be on both platforms that doesn't split your live audience: stream live on one, and post clips and VODs to the other.

Instead of broadcasting live to Twitch and YouTube simultaneously, you go live where your community is (usually Twitch), keep your whole live audience in one room, and put the highlights on YouTube as clips and uploads. You still get a YouTube presence working for discovery and longevity, but your live energy stays concentrated. For most small and mid-size streamers this captures most of the upside of "both platforms" without the community-splitting downside of true simulcasting, and it's less to set up and maintain. The clip pipeline is what makes this practical, because it turns the stream you already did into the YouTube content without a second live broadcast. Simulcasting and clip-distribution both put you on two platforms; they just split the cost differently, one splits your live room, the other splits nothing.

If you do simulcast, do it right

If the reach is worth it for your channel, a few things make simulcasting work better. Use combined chat so you can actually engage both audiences from one place, now that Twitch permits it. Pick the setup that fits your hardware honestly: if your upload or CPU is tight, use cloud restreaming rather than a local plugin that will degrade your stream quality trying to push two broadcasts. And still treat one platform as home, the place you point people to interact, rather than splitting your attention evenly, so the community has a center of gravity even while the broadcast goes to both.

FAQ

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

Yes. Since Twitch updated its simulcasting guidelines in October 2023, Affiliates and Partners can broadcast live to Twitch and YouTube simultaneously. You do it with a cloud restreaming service (like Restream), an OBS plugin (obs-multi-rtmp), or a browser studio (like StreamYard). It's permitted and the tools are straightforward.

Is multistreaming against Twitch's rules?

No, not anymore. Twitch used to restrict simulcasting under its exclusivity terms, but it updated the simulcasting guidelines in October 2023 to allow streaming to other platforms at the same time. Twitch has also stopped penalizing combined chat. Many older guides still describe it as restricted, but in 2026 simulcasting to YouTube is allowed.

What is the best multistreaming software?

It depends on your hardware. Cloud restreaming (Restream) is best if you want to spare your CPU and upload bandwidth, because the fan-out happens on their servers, and it has a free Twitch-plus-YouTube tier. The OBS multi-RTMP plugin is best for full local control if you have the processing power and bandwidth. Browser studios like StreamYard are best for the simplest, least technical setup.

Does multistreaming hurt your growth?

It can, for a small channel. Multistreaming splits your live audience and chat across two platforms, and a fragmented chat makes each room feel emptier, which hurts the retention that grows a channel. The reach gain is marginal at small viewer counts while the community cost is real, so many small streamers grow faster by streaming live on one platform and posting clips to the other instead of simulcasting.

Do you need Restream to multistream?

No. Restream is one option (cloud restreaming), but you can also multistream locally with the OBS multi-RTMP plugin or through a browser studio like StreamYard. Restream's advantage is that it offloads the work to the cloud so your own machine only sends one stream, which matters if your CPU or upload bandwidth is limited.
