  Start screen sharing with a single 9-digit code.
  
  - Share up to 3 windows + audio together
  - Viewers just open a URL — no install, no login

  No meeting tool to open. No link to issue. Just share the code.

  WinCast is a screen and audio sharing extension for Chrome, built for fast collaboration and meetings.
  
  Start screen sharing with a single 9-digit code. Unlike a basic screen share, WinCast lets you combine up to 3 separate windows into one clean view — show a document, a chart, and a browser side by side, with audio included. No meeting tool to open, no link to issue, no software for viewers to install.
  
  How it works
  1. Open WinCast and start a session
  2. Pick up to 3 windows to share, plus audio
  3. Share the 9-digit code or link
  4. Viewers open it in any browser and watch instantly
  
  Why WinCast
  - Multi-window sharing: show up to 3 windows in one view
  - Audio sharing included
  - No install, no login, no signup for viewers
  - Direct WebRTC peer-to-peer: low latency, never proxied
  - Pincodes expire in 3 minutes, sessions cap at 1 hour for privacy
  
  Ideal for collaboration, team meetings, presentations, remote work, pair programming and quick demos.
  
  Free to use.
