WebRTC (Web Real-Time Communication) is a free, open-source project that provides web browsers and mobile applications with real-time communication capabilities via simple APIs. In platforms like Arcane Mirage, WebRTC enables peer-to-peer data sharing, audio-video conferencing, and interactive streaming without plugins or additional software installations. WebRTC supports secure, low-latency communication between browsers, devices, and servers, making it ideal for applications suchas live streaming, online collaboration, virtual events, and remote training. By integrating WebRTC with Unreal Engine, developers can enhance multiplayer experiences, facilitate real-time interactions, and enable seamless communication features in real-time 3D applications, games, and virtual environments.
