Did YouTube add live co-streaming?
The Twitch Killer Feature
YouTube launched "live co-reactions" in 2026, allowing creators to live-react to streams from other channels directly from mobile devices.
The New Live Features
Private rehearsal mode: Test your setup in private, then go public with one click.
Dual orientation: Broadcast horizontal and vertical simultaneously to reach wider audiences.
Mobile co-streaming: React to other creators' streams in real-time from your phone.
Why This Matters
Over 30% of YouTube viewers tune into live streams daily. These features directly compete with Twitch's core functionality. Combined with YouTube's superior monetization, many Twitch creators are considering the switch in 2026.
