How do I stream to YouTube and Twitch at the same time?
YouTube and Twitch are the two biggest live destinations, and plenty of creators want both — YouTube for discovery and VODs, Twitch for community. You do not have to choose. Here is how to go live on both at once from a single encoder without doubling your upload.
Why two direct outputs are a poor fit
OBS can push to one service at a time out of the box. Plugins can add a second output, but each output re-uploads the full stream from your PC, which doubles your upload and CPU load and increases the chance of drops on a normal home connection.
Set it up with a relay
Publish a single feed to a restreaming service and add YouTube and Twitch as destinations. The service relays a copy to each platform server-side, so your upload stays the same whether you are live on one platform or five.
- In OBS, point your stream server and key at the relay.
- Add Twitch with its stream key, and YouTube with its RTMPS key.
- Start streaming once — both platforms go live together and are monitored separately.
Set bitrate for the stream you actually have
Pick a bitrate your connection can comfortably sustain. A stable stream at 6 Mbps is better than a shaky one at 9 Mbps. A copy-first relay delivers that single encode to both platforms without re-encoding in the middle.
Frequently asked questions
Does Twitch allow simulcasting to YouTube?
Twitch updated its simulcasting rules in 2024 to permit streaming to other platforms at the same time. Always check the current terms of each platform you relay to.
Will streaming to both lower my quality?
No. A copy-first relay delivers your single encode to each platform without re-encoding, so quality matches your source.
Can I record while streaming to both?
Yes — turn on recording for the stream and Stream Repeater captures it to a VOD library you can download from.
