How to stream to TikTok and Twitch at the same time

Stream to TikTok and Twitch at the same time from one computer: Twitch connects once with a sign-in, TikTok takes a fresh key per session, and one upload feeds both.

Updated November 5, 2026 · 4 min read

To stream to TikTok and Twitch at the same time, connect Twitch to StreamLive Pro once with a sign-in, and before each broadcast paste a fresh TikTok server URL and stream key. Tick both channels and press start. StreamLive Pro fetches the current Twitch key by itself at the start of every broadcast; the TikTok key is the only thing you bring each time. Your computer uploads one stream, and two destinations fit in the 7-day trial.

Before you start

• TikTok must have given your account a stream key. TikTok decides who can stream from a computer, says its access requirements may vary by country or region, and may withdraw trial access if you do not go live enough in the first week (TikTok LIVE Studio: FAQ). Without a key, TikTok live is possible only from the TikTok app.
• A Twitch account. Twitch keeps your stream key in the Creator Dashboard under Settings, then Stream (Twitch Help: Stream key FAQ). With the sign-in connection you do not need to copy it.
• Each site's rules. Twitch and TikTok each have their own community rules and any agreements you signed with them. Check them before you send the same content to both.
• A StreamLive Pro account. The browser studio covers this pair on every plan and in the trial. OBS or vMix as the source needs a paid plan (see the /pricing?lang=en page).

Steps

1. Connect Twitch. On Connections click Connect on the Twitch card and approve on Twitch's own screen.
2. Set the Twitch title and category. Set them in your Twitch dashboard. They are kept on Twitch, not in StreamLive Pro.
3. Get the TikTok key. In TikTok, start a LIVE with streaming software and copy the Server URL and the Stream key.
4. Paste the TikTok key. The first time, add TikTok Live on Connections. Later broadcasts ask for the new key in one step when you go live, and the channel shows "Key ready" once it is saved.
5. Open the studio. Click New stream and pick Browser Studio, or Stream from software like OBS (RTMP / SRT) on a paid plan. Add your camera, microphone, and the game or app window through screen share.
6. Tick Twitch and TikTok and start. In the Channels list tick both and press Start stream. Twitch goes live by itself.
7. Press Go LIVE in TikTok if it asks. Some TikTok setups go public only after you press Go LIVE there once the picture arrives.
8. End. Press Stop stream, and end the TikTok LIVE if it is still open.

Wide for Twitch, upright for TikTok

Twitch viewers mostly watch a wide 16:9 picture; TikTok is watched on upright phones. Both receive the same picture: StreamLive Pro does not make a separate vertical version. For a game, a wide picture usually serves Twitch best; keep your face cam and any text you want TikTok viewers to see near the centre, inside the 9:16 safe-frame guide (Safe-zone guides for vertical and square viewers). If TikTok is your main audience, send a vertical picture from an encoder instead.

Limits to know

• Twitch chat is read inside StreamLive Pro but you cannot reply to it there, and TikTok comments are not read; live chat covers YouTube and Facebook (with replies), Twitch and Kick (read only). Keep both chats open on their own sites to answer.
• The TikTok part cannot start unattended at a set time, because it needs a fresh key from you.
• Shorts cut after the live can go to TikTok only when you post them yourself from the Publish screen, one at a time and not on a schedule: Post a video to TikTok from your computer.

Frequently asked questions

Can I stream to TikTok and Twitch at the same time without OBS?

Yes. The browser studio sends your camera, microphone and screen, and StreamLive Pro sends the broadcast to both, as long as TikTok has given your account a stream key.

Do I need to copy my Twitch key?

No, if you connect Twitch with a sign-in. StreamLive Pro fetches the current Twitch key at the start of every broadcast. Only TikTok needs a fresh key each time.

Does streaming to both need double the upload?

No. You upload one stream to StreamLive Pro and the copies to Twitch and TikTok are made on our servers.

Can I read Twitch chat and TikTok comments in StreamLive Pro?

Twitch chat yes, read only; TikTok comments no. Live chat in StreamLive Pro reads YouTube and Facebook (with replies), Twitch and Kick (read only). Keep the Twitch chat and the TikTok app open on their own to answer.

Am I allowed to stream the same content to Twitch and TikTok?

That depends on each network's rules and any agreement you have with them. Check both before you stream.
