How to Multistream on OBS to 7 Platforms at Once (2026)
OBS Studio is the most powerful free streaming software available. But by itself it only streams to one destination at a time. This guide covers two methods for streaming from OBS to YouTube, Facebook, Twitch, TikTok, X, Instagram, and LinkedIn simultaneously — and which method is right for your setup.
The Limitation of Native OBS Multistreaming
OBS 30 introduced a native multitrack feature, but it is limited to simulcasting to a small number of pre-approved platforms and requires configuration per platform. For true fan-out to 7+ destinations simultaneously — including custom RTMP targets — you need either the Multiple RTMP Outputs plugin or a relay service like Stream24.
The two methods have genuinely different tradeoffs. Neither is universally better. The right choice depends on your technical comfort level, your hardware, and how many platforms you need.
OBS Multiple RTMP Output Plugin
- Completely free
- No third-party account needed
- Works offline
- Multiplies your upload bandwidth
- Manual configuration per platform
- No stream health dashboard
- Plugin maintenance is community-driven
Stream24 + OBS (Relay Service)
- One stream from your machine
- Stream24 handles all fan-out
- Stream health per platform
- OBS browser dock integration
- Manage destinations from web or phone
- Requires a Stream24 account (free trial, no card)
Option 1 — OBS Multiple RTMP Output Plugin (Free, Manual Setup)
The obs-multi-rtmp plugin adds a panel to OBS that lets you define multiple RTMP output targets. Your computer encodes once and sends separate streams to each destination.
Bandwidth warning: If you stream at 6 Mbps to 5 platforms, your upload usage is 30 Mbps. Most home internet connections cannot sustain this. Check your upload speed before this approach.
Installation Steps
Go to the obs-multi-rtmp GitHub releases page and download the correct installer for your OS (Windows, macOS, Linux).
Run the installer, then close and reopen OBS. A new panel called "Multiple RTMP outputs" will appear in your docks menu.
In the panel, click Add. Enter the RTMP URL and stream key for each platform — YouTube, Twitch, Facebook, etc. You must add each platform individually.
Click Start on each output in the panel. OBS will begin sending separate streams to each destination. Monitor your upload bandwidth in Task Manager or Activity Monitor.
Option 2 — Stream24 with OBS (Recommended)
With Stream24, your OBS encodes one stream and sends it to the Stream24 relay server. Stream24 then fans it out to all enabled platforms simultaneously. Your upload load is the same as a single stream. Platform management happens in the Stream24 dashboard or via the OBS browser dock.
Step-by-Step: Set Up Stream24 with OBS
Go to app.stream24.io/register. No credit card required. Your 7-day Pro trial starts immediately. Full access to all platforms and features.
In the Stream24 dashboard, go to Destinations. Add each platform — YouTube, Facebook, Twitch, TikTok, X, Instagram, LinkedIn. Paste the stream key for each from the platform's live settings. Enable or disable platforms per broadcast.
In the Stream24 dashboard, your ingest details are shown on the main page. Copy both the Server URL and the Stream Key.
Open OBS. Go to Settings > Stream. Set Service to Custom. Paste the Stream24 Server URL and Stream Key. Click OK.
Click Start Streaming in OBS. Stream24 receives your stream and immediately relays it to every enabled platform. All platforms go live within seconds of each other.
How to Add the Stream24 OBS Browser Dock
The OBS browser dock lets you control your Stream24 destinations, check stream health, and go live — all from inside OBS without switching windows or tabs.
In OBS, go to View > Docks > Custom Browser Docks.
Enter "Stream24" as the dock name. For the URL, enter: app.stream24.io. Click Apply.
The Stream24 panel will appear. Drag it to any position in your OBS layout. From here you can toggle destinations, see stream health indicators, and manage your broadcast without leaving OBS.
No other multistreaming service offers an OBS browser dock. This is a Stream24 exclusive. It keeps your desktop clean and your workflow fast.
Recommended OBS Settings for Multistreaming
These settings balance quality against the real-world constraints of multistreaming — primarily upload bandwidth and CPU headroom.
| Setting | Recommended Value | Notes |
|---|---|---|
| Encoder | x264 or NVENC/AMF | Use hardware encoder (NVENC/AMF) if available — reduces CPU load significantly |
| Bitrate | 4000–6000 kbps | 6000 kbps for 1080p60. Lower if upload is limited. Stream24 handles transcoding. |
| Keyframe Interval | 2 seconds | Required by most platforms. Set to 2 in OBS. |
| Resolution | 1920×1080 | Downscale in Output settings if needed. Canvas resolution can stay at 1080p. |
| FPS | 30 or 60 | 60fps requires significantly more bitrate. 30fps is fine for most content. |
| Audio Bitrate | 160 kbps | 128 kbps minimum for music content. 160 is standard for talk and mixed. |
| Profile | high | For x264. Gives better quality at the same bitrate vs baseline or main. |
| Tune | zerolatency | Reduces encoding latency. Use for live streaming. |
Summary: Which Method Should You Use?
Use the OBS plugin if you have a fast upload connection (50 Mbps+), need no subscription, stream to three or fewer platforms, and are comfortable with manual configuration.
Use Stream24 with OBS if you want one stream from your machine, need stream health monitoring, want to manage destinations from a dashboard or your phone, or plan to use the OBS browser dock to keep your desktop clean.
