YouTube, TikTok, Facebook, Twitch, Instagram Live — simultaneously. Whether you want to go live on every platform at once using free software, a hardware encoder, or a cloud multistreaming service, this guide covers every method, every platform, and every budget. No technical background required.
Everything covered in this article — click any section to jump straight to it.
Multistreaming (also called simulcasting) means broadcasting your live video to more than one platform at exactly the same time. While you are live on YouTube, the same stream is also going out on TikTok, Facebook Live, Twitch and Instagram Live — reaching every audience you have built, simultaneously, with no extra effort.
For creators, this is transformational. You do one broadcast and reach four or five times the audience. For businesses, it means a product launch, town hall or event is visible everywhere at once. For churches, a service goes out to YouTube, Facebook and the church website at the same time.
The technology to do this is now accessible to everyone — from free software solutions to dedicated hardware that does it automatically with no computer at all.
There are three fundamentally different approaches to multistreaming. Each has different costs, complexity and quality trade-offs.
| Method | Cost | Needs a PC? | Stream Quality | Best For |
|---|---|---|---|---|
| OBS + free multistream service | Free | ✓ Yes | Good (depends on PC) | Creators, gamers, beginners |
| Hardware encoder | Hardware cost, then free | ✗ No PC needed | Excellent (dedicated hardware) | Churches, events, fixed installs |
| Cloud multistreaming service | Monthly subscription | ✓ Yes (or hardware) | Good (extra encode hop) | Professionals, large audiences |
This is the most popular method for creators because it costs nothing. OBS Studio is free streaming software. A multistream service (like Restream.io or Castr) takes your single OBS stream and forwards it to every platform simultaneously. You stream once — they split it everywhere.
Go to obsproject.com and download OBS Studio. It is free, runs on Windows, Mac and Linux, and has no watermark or time limits.
Restream.io free plan lets you stream to two platforms simultaneously. Their paid plan (around £14/month) adds unlimited platforms including TikTok, YouTube, Facebook, Twitch, LinkedIn and more.
In your Restream dashboard, connect each platform — YouTube, Facebook, TikTok, Twitch etc. Restream guides you through each one. It handles the stream keys automatically.
In OBS: Settings → Stream → Service: Restream.io → connect your Restream account. Now OBS sends one stream to Restream, and Restream forwards it to all your platforms.
Click Start Streaming in OBS. Within seconds you are live on every platform you connected. Check each platform to confirm — it usually takes 20-30 seconds for streams to appear.
A standalone hardware encoder is a small box that connects directly to your camera's HDMI output and your internet router, then streams to multiple platforms simultaneously — with no computer needed at all. You configure it once via a web browser, then unplug the laptop. Every time you power it on, it goes live automatically.
This is the professional standard for fixed locations — churches, conference rooms, schools, sports venues and broadcast facilities. No software crashes. No Windows updates interrupting a live service. No IT knowledge needed on the day.
Cloud multistreaming services sit between your encoder (software or hardware) and the platforms. You send one stream to the service, they forward it everywhere. The main ones are Restream.io, Castr, Streamyard and Switchboard Live.
| Service | Free Plan | Platforms | Best For | Works With Hardware Encoder? |
|---|---|---|---|---|
| Restream.io | ✓ 2 platforms | 30+ | Creators, OBS users | ✓ Yes |
| Castr | ✗ Paid only | 40+ | Professional streams | ✓ Yes |
| Streamyard | ✓ Limited | 8+ | Interviews, talk shows | ⚡ Browser based |
| Switchboard Live | ✗ Paid only | 30+ | Enterprise, events | ✓ Yes |
| Hardware encoder direct | ✓ Free after hardware | 4-6 simultaneous | Fixed installs, no PC | ✓ Built in |
YouTube is the most creator-friendly platform for live streaming. It supports RTMP from any source. You get your stream key from YouTube Studio → Go Live → Stream. Set the server URL to rtmp://a.rtmp.youtube.com/live2 and paste your stream key into OBS or your hardware encoder. YouTube Live supports up to 4K streaming. There is no follower requirement to go live on desktop.
Twitch is the dominant gaming platform. Your RTMP server URL is the nearest Twitch ingest server — find yours at stream.twitch.tv/ingests. Stream keys are in your Twitch Creator Dashboard → Settings → Stream. Twitch recommends 1080p60 at 6,000 Kbps maximum. Note that Twitch has strict rules about simultaneously streaming the same content on other platforms — check their Terms of Service before simulcasting.
TikTok Live supports RTMP streaming for accounts with 1,000+ followers. The stream key and RTMP URL are available via TikTok Live Studio or the TikTok LIVE Centre. Alternatively, use a service like Restream.io which handles the TikTok integration automatically without needing direct RTMP access. TikTok Live works best at vertical (9:16) format — in OBS, set your canvas to 1080×1920 for TikTok, or use a separate output scene.
Facebook Live stream keys are found in Creator Studio → Live Dashboard → Create Live Video → Use Stream Key. The RTMP URL is rtmps://live-api-s.facebook.com:443/rtmp/. Facebook Live supports up to 1080p. Live videos on Facebook Pages perform significantly better in the algorithm than recorded uploads — streaming live gives you organic reach that pre-recorded video does not get.
Instagram Live via RTMP is available through third-party tools — Instagram does not give you direct RTMP access from its settings. Services like Yellow Duck, Restream.io and Streamyard connect to Instagram Live on your behalf. You stream to their service via RTMP, they forward it to Instagram. This requires a phone with Instagram installed and logged in during the stream.
