A WebRTC-based peer-to-peer screen sharing feature that supports one-to-one screen sharing (multiple viewers are not supported yet). Within a local area network (LAN), screen sharing is generally stable, while cross-network sharing may or may not succeed. Click the “Start Sharing” button. After the program finishes initialization, share the generated viewer link with others to start screen sharing. This feature is built entirely on standard browser capabilities (if it does not work, please upgrade to the latest version of browsers such as Google Chrome or Edge). No additional software installation is required. The shared content is transmitted directly through a peer-to-peer connection without passing through a server, making it more secure and privacy-friendly. WebRTC support is generally better on desktop browsers and usually works normally on personal computers. On mobile devices, if you encounter errors related to “getDisplayMedia”, it means the browser does not support this feature.
