Join a Session

Scan or paste a code from the host.

Choose Pairing Method

Generate an offer, then let your peer scan the code(s) with their camera. No typing required.

frame 1 / 1

Hold the guest's camera a few inches from the screen at max brightness. If it's a single frame, it's ready to scan right away — if multiple frames, use Next once the guest confirms each one captured.

Generate a compressed text token and share it however you like (chat app, email, etc).

Optional: if you run a lightweight signaling relay, enter its WebSocket URL to auto-exchange codes. Chat/files still travel directly peer-to-peer — the relay only helps the two browsers find each other.

Share this room code with your peer:
