How to stream to Twitch from your browser

Stream to Twitch from a browser with no OBS: connect Twitch once and StreamLive Pro fetches the stream key for every broadcast, or paste the key yourself.

Updated November 5, 2026 · 3 min read

To stream to Twitch from your browser, connect your Twitch account to StreamLive Pro once. From then on StreamLive Pro fetches your Twitch stream key at the start of every broadcast, so you only tick Twitch and press start. You can also paste the key yourself on the Twitch (stream key) card, which is handy if you do not want to sign in. Either way, the same broadcast can go to YouTube, Facebook and other networks at the same time.

Before you start

• A Twitch account. Any Twitch channel can stream. Twitch keeps the stream key in the Creator Dashboard, under Settings, then Stream (Twitch Help: Stream key FAQ).
• Title and category set on Twitch. Set them in your Twitch dashboard before you start; StreamLive Pro sends the picture and sound.
• A StreamLive Pro account. The browser studio works on the 7-day trial. OBS or vMix as the source needs a paid plan (see the /pricing?lang=en page).
• A stable upload. Twitch's own guidelines say a stable stream is better than pushing for quality your connection cannot hold (Twitch Help: Broadcasting guidelines). With StreamLive Pro you upload one stream, whatever the number of networks: Upload speed and bitrate for multistreaming.

Steps

1. Connect Twitch. Open Connections, find Twitch and click Connect. Sign in on Twitch's own screen and approve. The card then shows your channel.
2. Open the studio. Go to Live stream and choose Browser Studio, or Stream from software like OBS (RTMP / SRT) if you produce in OBS or vMix.
3. Add your sources. Camera, microphone, screen share or a game window, guests by link, logo and lower thirds. See Your first live broadcast, step by step for a first setup.
4. Tick Twitch. In the Channels list tick Twitch, plus any other networks for this broadcast.
5. Go live. Press Start stream. StreamLive Pro asks Twitch for your current stream key and starts sending. Your channel goes live on Twitch a few seconds later.
6. End. Press Stop stream. Press Record during the broadcast if you want StreamLive Pro to keep the full recording; otherwise our temporary copy is removed about two hours after.

With the stream key instead of a sign-in

Add Twitch (stream key) on Connections:

1. On Twitch open Creator Dashboard, then Settings, then Stream.
2. Under Primary Stream key click Copy and paste it into the card. A Twitch key starts with live_; the card refuses one that does not.
3. In the server field paste rtmp://live.twitch.tv/app/ (it is shown as the example in the field).

The Twitch key stays the same until you reset it. If you reset it on Twitch, paste the new one, because the old key stops working. With the sign-in connection that step is not needed: the key is fetched fresh each time.

Frequently asked questions

Can I stream to Twitch without OBS?

Yes. The browser studio sends your camera, microphone and screen straight from the browser, and StreamLive Pro forwards the broadcast to Twitch.

Do I have to paste my Twitch stream key?

No. If you connect Twitch with a sign-in, StreamLive Pro fetches the key for every broadcast. Pasting the key is an alternative.

Can I stream to Twitch and YouTube at the same time?

Yes. Tick both in the same broadcast. You upload one stream and StreamLive Pro sends it to both, within the number of destinations your plan allows.

I reset my Twitch stream key. What now?

With the sign-in connection nothing, the new key is fetched next time. With a pasted key, copy the new one from Creator Dashboard and paste it.

Can I read Twitch chat in StreamLive Pro?

Yes, read only. Twitch messages appear in the live chat next to the other networks. To reply, keep Twitch chat open in its own window.

Does StreamLive Pro post my videos to Twitch?
