Picture and sound flow directly between the devices. The server relays only what is needed to open the connection.
Show this computer's screen, a window, or a single tab on another device's browser. Share a six-digit number and that is the whole setup. The picture never passes through a server — it goes straight between the devices.
Questions
Do I need an account?
No. Both sides just open this page.
Is what I show stored anywhere?
No. Picture and sound go directly between the devices; the server relays only connection details.
Can I cast a phone screen?
No — browsers are not given access to the device display. A phone works fine as the receiving side.
How many people can watch?
Everyone in the same numbered room. Each additional viewer uses more of the sender upload.
How do I stop?
Press Stop casting, or use the stop-sharing control your browser shows. Either works.
Is the number reused?
A fresh one is made each time the page opens, and it stops working once you close it.
