Zero install
Never making the other person download anything is our first product principle. Sending and watching both live in the browser.
End-to-end encrypted
Media is encrypted end to end. It connects directly when possible and can use a secure relay that cannot decrypt it.
Low latency
Direct peer-to-peer transport — low enough to follow your cursor in real time.
Cross-platform
Share from a desktop browser; watch from a desktop, phone, tablet, or TV browser.

FAQ

No. Media is encrypted end to end and connects directly when possible. On restricted networks, a relay only forwards encrypted data it cannot decrypt; the video is not stored.
