Multistream

Multistreaming (also written as multi-streaming or multistream) is the practice of broadcasting a single live stream simultaneously to two or more platforms at the same time. Instead of choosing between Twitch, YouTube, TikTok, Kick, Facebook, or any other platform, a multistream setup sends the same video and audio feed to all of them at once.

A single OBS session, one stream key, and your audience grows across every platform simultaneously.

How Multistreaming Works

At the technical level, multistreaming works by duplicating your outgoing stream and routing copies to multiple RTMP endpoints simultaneously. RTMP (Real-Time Messaging Protocol) is the standard used by virtually every streaming platform to receive broadcast feeds.

There are two main approaches:

1. Local multistreaming (OBS plugin method) You encode the stream once on your PC and send multiple RTMP outputs directly from your machine. This puts the bandwidth and encoding workload on your hardware. The advantage is no third-party dependency. The disadvantage is that your upload bandwidth needs to support multiple simultaneous streams (typically 6–12 Mbps per stream, multiplied by however many platforms you are streaming to).
2. Service-based multistreaming (Restream, Streamlabs, etc.) You send a single stream to a multistreaming service, which re-broadcasts it to your chosen platforms from their servers. Your encoder only uploads once. The service handles the distribution. This is more bandwidth-efficient and more reliable for most setups, though it introduces a small amount of latency and a dependency on the service’s uptime.

Most streamers use a combination: OBS or Streamlabs as the encoder, and either a plugin or a service to handle multi-destination routing.

Is Multistreaming Against Twitch TOS?

This is the most searched question in multistreaming and the answer changed significantly in 2023 and has remained stable since.

For Twitch Partners: Multistreaming is restricted by Twitch’s exclusivity clause in the Partner agreement. Twitch Partners agree not to simultaneously stream on competing platforms (specifically named: YouTube, Facebook Gaming, Kick, TikTok Live). Streaming to non-gaming platforms or personal/portfolio sites may be permitted but this is a grey area.

For Twitch Affiliates: There is no exclusivity requirement. Affiliates can multistream to any platform without violating Twitch TOS.

For non-Affiliate, non-Partner streamers: No restrictions at all. Stream wherever you want.

The practical reality for Partners: Some Partners have multistreamed to platforms like YouTube or Kick and faced warnings or termination of their Partner status. Others have done so openly without consequence. Twitch’s enforcement has been inconsistent, but the TOS restriction is real. If your Twitch partnership income matters to you, multistreaming to competing platforms is a genuine risk.

Twitch multistream rules summary:

• Partners: restricted from simultaneous streaming on competing platforms
• Affiliates: no restriction
• Everyone else: no restriction
• Delayed streaming (VOD uploads after a live stream) is allowed for everyone

How to Multistream on OBS

OBS Studio does not natively support multiple simultaneous RTMP outputs in its standard settings, but it can be enabled through two methods: the built-in multiple output feature (available since OBS 30.x) or third-party plugins.

Method 1: OBS Native Multiple Outputs (OBS 30+)

OBS Studio added a Multiple Output feature starting in version 30. Here is how to use it:

1. Open OBS Studio (make sure you are on version 30 or later)
2. Go to Tools > Multiple Output Plugin (or find it in the Tools menu depending on your version)
3. Click Add to add a new output
4. Enter the RTMP server URL and stream key for the second platform
5. Configure the output settings (bitrate, resolution, encoder)
6. Repeat for each additional platform
7. Start your main stream as normal, then start each additional output

The outputs can use different settings from your main stream. You can, for example, send a higher-quality stream to YouTube and a lower-bitrate stream to a secondary platform.

Method 2: OBS Multistream Plugin (Prism Live Studio or Aitum)

For more control and a better interface, dedicated plugins handle multistreaming more elegantly. See the plugin sections below.

Can You Multistream on OBS for Free?

Yes. OBS Studio is free and open source. The native multiple output feature is free. Several OBS multistream plugins are also free. The only cost involved is if you choose to use a paid multistreaming service like Restream.

Best OBS Multistream Plugins

Several plugins extend OBS’s multistreaming capabilities beyond the native implementation.

Aitum Multistream OBS Plugin

The most widely recommended OBS multistream plugin in 2026. Aitum Multistream is specifically designed to add multiple RTMP output support to OBS Studio with a clean interface and straightforward configuration.

What Aitum Multistream does:

• Adds a dedicated multistream panel to OBS
• Lets you configure unlimited stream destinations
• Each destination can have independent settings (different bitrates, resolutions, encoder settings)
• Supports custom RTMP URLs and all major platform presets
• Free to use

Aitum Multistream setup:

1. Download the Aitum Multistream plugin from aitum.tv
2. Install it into your OBS plugins folder
3. Restart OBS
4. Go to Tools > Aitum Multistream in OBS
5. Click the + button to add destinations
6. Enter each platform’s RTMP URL and stream key
7. Toggle destinations on or off before starting your stream

The “no docked” version of Aitum Multistream refers to running the plugin panel as a floating window rather than docked to the OBS interface. Some users prefer this for multi-monitor setups.

Restream Multistreaming Plugin for OBS

Restream offers its own OBS plugin that connects your OBS directly to your Restream account, which then distributes your stream to all your configured destinations. This combines the local encoding of OBS with the server-side distribution reliability of Restream.

Adom Multistream Plugin

Adom is a less widely known but functional option for OBS multistreaming. It works similarly to Aitum, adding multiple output destinations to OBS. Available on GitHub for manual installation.

Meld Multistream

Meld is a newer multistream tool that integrates with OBS and focuses on simplicity. It handles the multi-platform routing through a lightweight service layer while keeping the configuration straightforward for streamers who do not want to manage RTMP details manually.

Aitum Multistream

Aitum Multistream deserves its own section because it has become the default recommendation for OBS multistreaming in 2026.

Key features:

• Free OBS plugin with no usage limits
• Add as many stream destinations as you want
• Each destination is independently togglable (turn individual platforms on or off without reconfiguring)
• Supports all RTMP-compatible platforms: Twitch, YouTube, TikTok, Kick, Facebook, LinkedIn Live, custom RTMP
• Different encoder settings per destination
• Works with OBS 28 and later

Aitum Multistream vs. Restream: Aitum is a local plugin, meaning it runs on your PC and uses your upload bandwidth. Restream is a cloud service, meaning it uses Restream’s servers to re-distribute. For PCs with strong upload speeds (50+ Mbps), Aitum is simpler and has no service dependency. For setups with limited upload bandwidth, Restream is more practical.

Where to get it: aitum.tv/multistream or search “Aitum Multistream” on GitHub.

Restream Multistreaming

Restream.io is the best-known multistreaming service and handles the largest share of multistream traffic in 2026. It works by accepting a single stream from your encoder and re-broadcasting it to up to 30+ platforms simultaneously from Restream’s own servers.

How Restream multistreaming works:

1. Create a Restream account at restream.io
2. Add your destination channels (YouTube, Twitch, Kick, Facebook, TikTok, etc.)
3. Restream provides you with a single RTMP URL and stream key
4. Point your encoder (OBS, Streamlabs, etc.) at the Restream RTMP endpoint
5. Start streaming. Restream handles all distribution.

Restream free plan: The free plan allows streaming to two destinations simultaneously with Restream branding. The paid plans remove the branding, add more destinations, and include features like multistream chat and analytics.

Multistreaming services reliability uptime comparison: Restream has the strongest uptime track record among commercial multistreaming services. Alternatives like Castr, Dacast, and Mux also offer reliable multistreaming services. For high-stakes streams where downtime is unacceptable, redundant setups (local backup + service-based primary) are the professional standard.

Streamlabs Multistream

Streamlabs (formerly Streamlabs OBS) offers multistreaming through its Streamlabs Ultra subscription. The multistreaming feature is built directly into the Streamlabs interface and does not require a separate plugin.

How to multistream on Streamlabs:

1. Subscribe to Streamlabs Ultra
2. Open Streamlabs and go to Settings > Stream
3. Find the Multistream section
4. Add your destination platforms
5. Enter stream keys for each platform
6. Start streaming normally. Streamlabs sends to all configured destinations.

Streamlabs multistream chat: Streamlabs Ultra also includes a unified multistream chat that combines chat messages from all platforms into a single feed. This means you can read and respond to Twitch chat, YouTube chat, and Kick chat in one window without switching between tabs.

Streamlabs vs. Restream for multistreaming: Streamlabs multistreaming is more convenient if you already use Streamlabs as your encoder since everything is in one place. Restream is more platform-agnostic and works with any encoder. For complex setups with many destinations, Restream’s dedicated service tends to be more reliable.

StreamElements Multistream

StreamElements (SE.Live) offers multistreaming as part of its streaming toolkit. Like Streamlabs, it integrates multistream functionality directly into the streaming workflow rather than requiring a separate service.

SE Live multistreaming works through the StreamElements overlay and alert system, combining multistream with StreamElements’ strong overlay customization tools. The multistream chat overlay from StreamElements is particularly well-regarded for its customization options and visual flexibility.

StreamElements multistream OBS plugin connects OBS to StreamElements’ overlay and alert systems and can also handle multi-destination output in conjunction with SE Live.

StreamYard Multistreaming

StreamYard is a browser-based streaming platform that handles multistreaming without requiring any local software installation. You open a browser, create a StreamYard studio, add your destinations, and go live. StreamYard handles encoding and distribution from its own servers.

Best for: Streamers who want multistreaming without installing software, interview-format streams, and creators prioritizing ease of use over maximum technical control.

StreamYard multistreaming supports: YouTube, Facebook, LinkedIn, Twitch, Twitter/X, and custom RTMP.

StreamYard vs. OBS for multistreaming: StreamYard is significantly easier to set up but gives less control over encoding settings and overlay customization. OBS with Aitum gives more power but requires more configuration.

Best Multistreaming Platforms Compared

Best multistreaming platform overall in 2026: Aitum Multistream for OBS users who can support the bandwidth. Restream for everyone else.

Best multistreaming service for reliability: Restream and Castr have the strongest uptime records.

Best multistreaming tools for low-end PCs: Restream or StreamYard. Since the encoding happens on Restream’s servers, your PC only needs to handle a single stream output rather than multiple simultaneous encodes. This significantly reduces the load on lower-end hardware.

Multistream Chat and Chat Overlays

One of the biggest operational challenges with multistreaming is managing chat from multiple platforms simultaneously. Viewers on Twitch see different chat from viewers on YouTube and Kick, and responding to all of them from separate tabs is impractical.

Multistream chat solutions:

• Restream Chat: Included with Restream accounts. Aggregates messages from all connected platforms into a single dashboard. Messages are color-coded by platform source.
  
  
• Streamlabs Multistream Chat: Available with Streamlabs Ultra. Integrated directly into the Streamlabs interface.
  
  
• Multistre.am chat overlay: A lightweight browser-based tool for combining chat feeds into a single OBS browser source overlay.
  
  
• StreamElements multistream chat overlay: More customizable than most alternatives. Supports custom CSS for visual styling.
  
  

Best multistream chat for OBS overlays: Restream Chat’s browser source overlay is the most commonly used. You get a URL from Restream that you add as a browser source in OBS, and the unified chat appears on stream.

How to Multistream to Specific Platform Combinations

How to Multistream to Twitch and YouTube

1. Set up Aitum Multistream or a Restream account
2. Add Twitch as destination 1: use your Twitch RTMP ingest URL and stream key
3. Add YouTube as destination 2: use your YouTube RTMP URL and stream key
4. Start streaming from OBS or your encoder

Note: If you are a Twitch Partner, review the TOS considerations above before multistreaming to YouTube.

How to Multistream to TikTok and Twitch

TikTok Live RTMP access is not universally available. You typically need to apply for RTMP access through TikTok’s creator tools or use a third-party service that has TikTok integration (Restream and StreamYard both support TikTok multistreaming where RTMP is available).

For TikTok specifically, content requirements differ from Twitch. TikTok expects more mobile-native vertical framing in many cases. Some streamers maintain separate stream configurations for TikTok (vertical 9:16) versus Twitch and YouTube (horizontal 16:9).

How to Multistream to YouTube Shorts and Twitch

YouTube Shorts live streaming operates differently from standard YouTube Live. As of 2026, you cannot directly multistream to YouTube Shorts live and Twitch simultaneously from a standard RTMP setup. YouTube Shorts live requires a vertical 9:16 feed, which is technically incompatible with a standard horizontal stream going to Twitch. Separate streams for each format is the current practical approach.

How to Multistream to Kick

Kick uses standard RTMP, so any multistream setup that supports custom RTMP endpoints supports Kick. Add Kick’s RTMP ingest URL and your stream key as a destination in Aitum, Restream, or any other multistream tool.

Best Multistreaming Tools for Low-End PCs

Multistreaming from a low-end PC is entirely possible if you use the right approach. The mistake low-end PC streamers make is trying to run local multi-encoding, which multiplies the CPU and GPU workload with each additional stream destination.

The solution is cloud-based multistreaming, where your PC only encodes and uploads one stream and the cloud service handles distribution:

Best options for low-end PCs:

• Restream: Send one 4–6 Mbps stream to Restream. They distribute to all your platforms. Your PC only encodes once.
• StreamYard: Browser-based, minimal local processing. Very light on system resources.
• Castr: Similar to Restream, cloud-side distribution from a single input stream.

For encoding, using NVENC (NVIDIA GPU encoding) or AMF (AMD GPU encoding) in OBS instead of x264 (CPU encoding) dramatically reduces the CPU load on low-end systems. Pair this with a cloud multistreaming service and a mid-range PC can stream to 5+ platforms without performance issues.

Managing Multiple Streaming Accounts Across Platforms

Multistreaming is about one stream going to many platforms. But a growing number of creators take a different approach: running separate, distinct streams on different platforms simultaneously, each tailored to its platform’s audience and format.

This is a fundamentally different operation. A vertical TikTok Live, a horizontal Twitch stream, and a YouTube Live can all run at the same time for different audiences, with different content, different overlays, and different personas. It is not multistreaming in the technical sense, but it is multi-account streaming at scale.

Running multiple simultaneous streaming accounts is where the infrastructure question gets serious.

Each platform, Twitch, YouTube, TikTok, Kick, and others, actively monitors for account linking signals. If two of your accounts share the same device, the same IP address, or the same session environment, the platforms connect them. Linked accounts face restrictions ranging from reduced reach to outright bans.

This is exactly the problem that Multilogin Cloud Phones are built for.

Why Cloud Phones Are the Right Infrastructure for Multi-Account Streaming

Each Multilogin Cloud Phone is a real Android device running in the cloud, with its own IMEI, Android ID, MAC address, and dedicated mobile IP. When you run a streaming account from a cloud phone, the platform sees a genuine, separate Android device with its own identity and history. There is no shared signal connecting it to your other accounts.

For a creator running three TikTok accounts for different niches, or an agency managing streaming accounts for multiple clients, this means each account operates in complete isolation. TikTok, Twitch, and YouTube cannot connect the accounts through device fingerprinting or IP matching because nothing is shared at the hardware level.

Persistent sessions maintain genuine account history. Each cloud phone’s app data, login state, and cache persist between sessions, exactly like a real phone someone uses daily. Your streaming accounts build real activity history over time, which improves algorithm treatment and platform trust.

One dashboard for all accounts. All cloud phones are managed from Multilogin’s single dashboard. Launch a session, run your stream from that cloud phone, close it. The session stays intact on that phone’s isolated environment, completely separate from everything else you manage.

For content creators building separate brand identities across platforms, or for agencies managing streaming accounts for multiple clients, cloud phones provide the infrastructure that makes multi-account streaming sustainable rather than a constant fight against platform enforcement.
