Share your screen with anyone, anywhere, with very low lag. Nothing to install, no sign-up. The video goes straight from your browser to theirs whenever it can.
Anyone with the room link can watch, and anyone in the room can share their own screen, one person at a time. Tick “Share system audio” in the picker to include sound (Chrome and Edge).
Room link
Anyone with this link can watch, and can share their own screen instead of yours. The link keeps working, so you can use it again.

Bigger groups or no internet?
The Share Screen app runs a small media server on your computer. It handles far more viewers (each one costs your computer almost nothing extra), works with no internet at all, and adds moderation such as locking the room and priority viewers.
Download for WindowsWindows 10/11, 64-bit. Unzip and run ShareScreen.exe; your browser opens and you share from there. Viewers still need nothing.
Connect directly on your network
Devices on the same network should connect straight to each other. When a firewall blocks that, the video takes the slower relay instead. Check the computer that's sharing, and any computer that's watching.
Windows
Open Start, type Allow an app through Windows Firewall and open it.
Click Change settings, find your browser (Google Chrome, Microsoft Edge, Brave or Firefox; there may be several entries) and tick Private for each. Click OK.
Make sure the network itself is private: Settings → Network & internet → Wi-Fi (or Ethernet) → your network → Private network.

To get Windows' "Allow access" prompt back instead, remove the browser's block rules in PowerShell (as administrator), then restart the browser:
