Stream to YouTube and TikTok Live at once

Publish to YouTube, which keeps the video on your channel afterwards, and to TikTok Live at the same time — with a single stream from your machine.

How to set it up

Point your encoder at Muxlyve
Set Muxlyve as the RTMP output server in the software you already use.
Connect YouTube via OAuth
Authorize your channel and Muxlyve fetches your live stream's RTMP URL and key, without digging through YouTube Studio.
Paste TikTok's RTMP key
Copy the URL and key from TikTok Live Studio and paste them into the TikTok destination.
Enable both and go live
Turn both destinations on and start. One signal, two platforms, no re-encoding.

Muxlyve only reads what it needs from your YouTube account (channel, RTMP key, chat and viewers): it never posts, modifies or deletes anything.
TikTok's key regenerates roughly every 2 hours; on long streams you'll need to paste it again.
YouTube keeps the stream on your channel when you finish, handy for reusing the content.
Unified chat covers Twitch and Kick; YouTube and TikTok aren't integrated in that window.
