How to multistream: the complete guide to several networks

How to multistream to several platforms at once: your own keys from your computer, or one upload sent on by a server. Upload needs, network rules and pair guides.

Updated November 5, 2026 · 8 min read

Multistreaming means sending one live broadcast to several networks at the same time, for example YouTube, a Facebook Page and Twitch. There are two ways to do it: your computer sends a separate copy to each network with your own stream keys, or you send one copy to a service whose servers pass it on to every network. StreamLive Pro offers both: StreamLive Pro Studio, free desktop software still in testing, works the first way, and the StreamLive Pro platform works the second way, from the browser today.

Which way suits you depends mostly on your upload speed and on how much you want managed for you. This guide compares the two, shows the steps, lists the rules each network sets, and links to a guide for every pair of networks.

The two ways, side by side

OBS Studio is free and open source, and it reaches several networks only through a plugin or a relay (obsproject.com, checked 5 November 2026). Both setups are explained in How to multistream with OBS: a plugin or a relay.

How much upload you need

A live broadcast needs a steady upload, not a fast download. With your own keys, every extra network adds a full copy on top, so three networks need about three times the upload of one. With one upload through a server, adding a network costs nothing on your side. The numbers and a simple way to measure your line: Upload speed and bitrate for multistreaming.

If your upload is close to the limit, choose the server way or fewer networks. A broadcast that drops frames on every network is worse than a clean one on two: My live stream drops frames or keeps buffering.

Way 1: your own keys from your computer

This way suits people with a strong upload who want to stay in desktop software.

• StreamLive Pro Studio. Free, professional streaming software for Windows and Mac. It goes live to several networks with your own stream keys, through custom RTMP and SRT outputs, and those outputs are free. Each output is its own upload from your connection. Version 0.5.0 is in testing and not downloadable yet; when it is released, the download will be on streamlivepro.io after a free sign-up. See /desktop?lang=en and What is StreamLive Pro Studio? The free desktop studio, defined.
• OBS or other encoder software. A multistream plugin or a relay sends the extra copies: OBS settings for multistreaming to several networks.

What you need for each network is its server address and stream key. How keys work, and which ones change every session: RTMP and stream keys: where to find them, what breaks and Persistent and one-time stream keys, network by network.

Way 2: one upload through StreamLive Pro

You send one stream, from the browser studio, from the phone, or from OBS and similar software, and our servers send it on to every network you tick. You can give each network its own title, and the broadcast ends everywhere when you press stop.

The number of networks one live can reach at once is set by your plan, and the trial allows two: How many networks can I stream to at once. In the trial you go live from the browser studio; OBS and other encoders are on paid plans: What the StreamLive Pro 7-day trial includes.

Steps

The server way, with StreamLive Pro:

1. Connect your networks. Open Connections. Sign in to YouTube, a Facebook Page, Twitch or Kick, and add a stream key for networks such as Instagram, TikTok, X or LinkedIn: Connecting your channels — YouTube, Facebook and the rest.
2. Open the live page. Go to Live stream and choose the source: Browser Studio, or Stream from software like OBS (RTMP / SRT) for OBS and other software.
3. Tick the networks. In the Channels list switch on every network for this live. Two Facebook Pages count as two.
4. Give each network its title, if you want. Open a channel to change its title and description: Give each network its own title in one live broadcast.
5. Paste fresh keys where needed. Instagram and TikTok give a new key for every session: Live on Instagram and TikTok with a stream key.
6. Start once. Press Start stream in the browser studio, or start streaming in your encoder. Each network shows the picture within a few seconds.
7. Check every network. Open each network once to see the picture. If one network fails, the others carry on: My live reached only some of the networks.

Common mistakes

• Reusing an old Instagram or TikTok key. It worked yesterday and is refused today. Paste the key of the new session.
• Picking a personal Facebook profile. Live goes to a Page you manage: My Facebook Page is not in the list.
• Too many own-key outputs for the line. Every network stutters at once. Remove outputs, or move to one upload through a server.
• Wide picture on a vertical network. Instagram and TikTok viewers watch upright. Plan the frame: Safe-zone guides for vertical and square viewers.
• Testing on the real audience. Rehearse with no network ticked first; the broadcast then goes only to your own watch page.
• A key that is refused. Check the server address and the key side by side: Stream key or server URL not accepted when saving.

Where StreamLive Pro fits

Use StreamLive Pro Studio, when it is released, if you want free desktop software and your upload carries every copy. Use the StreamLive Pro platform if you want one upload, sign-in connections, a title per network, and the rest of the work around the live: AI Shorts, scheduling, comments and analytics. Plans and the 7-day free trial are on the pricing page. Before you start, the basics of a first live are in How to live stream: the complete guide for 2026, and planning a regular show is in Schedule live streams and posts: the complete guide.
