Your streams never leave your network
Built on WebRTC peer-to-peer technology. Video flows directly between devices — no cloud, no recording, no data retention.
End-to-End Encrypted
WebRTC DTLS-SRTP encryption secures every video stream between browser and Apple TV.
No Cloud Video Servers
A lightweight signaling server coordinates the initial handshake, but all video streams flow directly point-to-point.
Password-Protected Rooms
Every room requires a unique code and password. Regenerate credentials anytime with one click.
Nothing Recorded
No video data is stored, persisted, or transmitted to any server. When you disconnect, it's gone.
Built for teams that move fast
Everything you need for real-time multi-screen collaboration, nothing you don't.
Adaptive Grid Layout
Automatically adjusts from 2×2 to 4×4 based on the number of active streams. Every pixel utilized.
Click-to-Focus
Select any screen to zoom it full-display for detailed inspection. Click again to return to the grid.
Smart Quality Scaling
Video quality adapts dynamically. Focused screens get full HD while background streams optimize for bandwidth.
Peer-to-Peer Encrypted
WebRTC direct connections mean video never touches a cloud server. Streams stay on your network.
Zero Installation
Screen sharers only need a modern browser. No plugins, no desktop apps, no IT approval required.
Up to 16 Screens
Scale from a quick pair programming session to a full operations center. The grid adapts to your team size.
