The OBS multi-RTMP plugin that runs entirely on your machine

Comparing OBS multi-RTMP options

There are several ways to stream to multiple RTMP destinations from OBS. Here's how they compare:

Solution	Cost	Local (no server)	RTMP targets	Vertical canvas
MultiStream OBS Plugin	€4.99 once	Yes	Unlimited	Yes
obs-multi-rtmp (community)	Free	Yes	Unlimited	No
Restream.io	$16–$49/month	No (cloud)	2–unlimited	No
Splitstream / Castr	$10–$25/month	No (cloud)	2–unlimited	No

Why not just use the free obs-multi-rtmp plugin?

The open-source obs-multi-rtmp plugin does the core job: adding multiple RTMP outputs to OBS. But it's limited to exactly that — raw RTMP outputs with no extra features.

MultiStream OBS Plugin adds on top of that:

• Vertical canvas output (9:16) for Shorts, TikTok, Instagram
• Unified multi-platform chat dock inside OBS
• Activity feed (followers, donations) from all platforms
• Chat commands (!start/!stop) to control outputs remotely
• OBS Blade remote control support
• Active support and updates

If you only need raw RTMP outputs and nothing else, the free plugin works. If you want a complete multistreaming setup in OBS, MultiStream OBS Plugin is the better choice.

How it works

Install the plugin, reopen OBS, and you'll see the Multiple Output panel in your docks. Add each platform (Twitch, Kick, YouTube, TikTok, Facebook — any custom RTMP), enter your stream keys, and click Start All. That's it.

Each output is independent — you can start or stop individual platforms without affecting the others.
