Three steps. No app install required on mobile.
Sign in on your laptop and click 'New Session'. A QR code appears instantly with a secure room ID.
Open your camera and scan the QR. No app download — it opens in your mobile browser automatically.
Drop files (up to 50 MB), send text or links. Both devices can send. Files transfer in real-time binary chunks.
Files travel as raw binary chunks, not base64 — 33% smaller, faster transfers.
UUID v4 room IDs with a 4-digit PIN. Max 2 devices per room. Third join attempts are rejected.
Rooms self-destruct after 5 minutes of inactivity. All data is in-memory — nothing persists.
Files never leave your local network. Transfers happen peer-to-peer via your local WebSocket server.
Real progress bars driven by actual chunk acknowledgment — not fake timers.
The join page is optimized for phone screens. No pinch-to-zoom, no tiny buttons.
