How to Multi-Stream IRL to Twitch and YouTube at the Same Time (2026 Guide)

Since Twitch removed its simulcast restriction, multi-streaming — going live on Twitch and YouTube (or Kick, or TikTok) at the exact same moment — has moved from "nice to have" to a standard ask for serious IRL streamers. The problem is that the usual desktop solutions (OBS with plugins, Restream, Castr) all assume you have a stable PC connection. If you are streaming IRL with a phone encoder or a Belabox-style SRTLA rig, you are operating on a mobile uplink that drops, degrades, and switches towers constantly — and those tools were not designed for that.

IRLHost is built for this specific use case. Here is how the cloud multi-stream workflow works, what you can and cannot do on each platform, and how to set it up.

Why desktop multi-streaming tools don't work well for IRL

The fundamental issue is the ingest path. A home OBS setup ingests from a local capture card over a wired connection and then pushes a finished RTMP stream to each platform. IRL streaming flips this: your encoder pushes an SRT or SRTLA stream from a mobile connection to a relay first, and that relay is responsible for delivering a clean feed downstream.

When you add multi-streaming on top of that, you need a relay that can also act as a cloud OBS — accepting your one mobile uplink and fanning it out to multiple destinations simultaneously, without requiring you to open a laptop in a backpack. That is exactly what IRLHost Studio does.

What IRLHost Studio does

IRLHost Studio is available on the Pro plan (€29.99/mo). It sits in the cloud between your encoder and your destination platforms and does two things at once:

• SRT/SRTLA relay: Bonds your mobile connections (multiple SIMs, Wi-Fi) into a single stable feed so that signal drops on one path do not interrupt your stream. Works with any SRT/SRTLA-capable encoder or app, including Belabox and IRL Pro.
• Cloud multi-streaming: Takes that single stable relay feed and pushes it simultaneously to Twitch, Kick, YouTube Live, and any Custom RTMP destination. You do not need a second device or a home PC running in the background.

Studio runs in the browser — OBS in the cloud. You configure your destinations once, and from that point your encoder only ever needs to connect to your IRLHost relay endpoint; the cloud handles the fan-out.

Platform support and limits

IRLHost Studio supports four destination types. The relay and multi-streaming features work the same way on all of them, but the bonus integrations (chat bot, Scene Control) differ by platform:

• Twitch: Full support. Relay, multi-streaming, automated chat bot integration, and Scene Control (automatic scene switching on connection events, plus chat commands for mods).
• Kick: Full support. Relay, multi-streaming, chat bot, and Scene Control — same feature set as Twitch.
• YouTube Live: Relay and multi-streaming supported. No chat bot integration and no Scene Control on YouTube.
• TikTok LIVE: Relay and multi-streaming via Custom RTMP, available on the Pro plan. No vertical cloud OBS, no Stream Keys, no chat bot, no Scene Control — IRLHost does not provide TikTok stream keys, so you need your own RTMP access from TikTok.
• Any Custom RTMP destination: Supported on the Pro plan. Send your feed to a self-hosted ingest, a CDN, or any platform that accepts a standard RTMP stream.

How to set up IRL multi-streaming with IRLHost

The setup involves three stages: configuring your encoder, connecting your destination platforms in Studio, and going live.

1. Configure your encoder

In your encoder app (Belabox, IRL Pro, or any SRT-capable encoder), set the output mode to SRT or SRTLA and point it at the relay endpoint shown in your IRLHost dashboard. Enable all available network interfaces (SIM cards, Wi-Fi) in your encoder for bonding — the more paths, the more resilient the relay connection.

2. Add your streaming destinations in IRLHost Studio

Open IRLHost Studio from your dashboard and add each platform you want to stream to as a destination, with its stream key. For a Custom RTMP target, enter the ingest URL and stream key manually.

3. Go live

Start your encoder. Once IRLHost Studio receives your feed on the relay endpoint, it pushes to all configured destinations at once. Your Twitch and Kick channels (if configured) also get the chat bot and Scene Control; YouTube Live receives the video feed without bot or scene switching.

Pricing

Cloud multi-streaming with IRLHost Studio requires the Pro plan at €29.99/mo. The entry Plus plan (€11.99/mo) covers your own private SRT/SRTLA relay connection, automatic scene switching, and chat commands for a single destination, but does not include Studio or multi-streaming. If you are on Plus and want multi-streaming, upgrade from your dashboard — your relay endpoint stays the same.

Is IRLHost Studio right for your setup?

If you stream IRL from a mobile rig and want to reach Twitch and YouTube simultaneously without a home PC running in the background, IRLHost Studio is designed for exactly that. The relay handles the unstable mobile uplink; Studio handles the fan-out. Full platform details and current plan pricing are at irlhost.gg/#pricing.
