Make the crowd loud.
Set up a live reaction wall, show a QR code or join code, and let the audience fire hearts, laughs, applause and fire from their phones. One phone hosts; a laptop, tablet, or big screen makes a great stage.
How Reaction Wall works
- Create a session and show the QR code or short join code.
- Participants open a reaction page with big emoji buttons.
- Every tap flies onto your screen in real time with the whole room's reactions.
- Reactions reach the host through a live browser-to-browser WebRTC connection.
Perfect for live moments
Use it at presentations, parties, classrooms, conferences, weddings, streams and live shows whenever the room needs a way to clap back.
Host anywhere
Run it from one phone, a laptop or a tablet, and throw the reaction wall up on a projector or TV for the whole room to see.
Privacy and connection limits
Reaction Wall does not require accounts and it does not build a central results database. The host browser holds the live session in memory. PeerJS Cloud is used for a short connection setup; after that, reactions use WebRTC data channels. Some restrictive networks may need relay infrastructure, and the wall ends when the host page closes. Do not use it for voting or any regulated decision.
Frequently asked questions
Do participants need an app or account?
No. They scan the QR code or open the join link in a current browser.
What happens when someone taps a reaction?
It flies onto the host screen instantly, joined by everyone else's taps.
Can people keep reacting?
Yes. Taps are unlimited, so the crowd can cheer and clap as long as you like.
