Learn Real-Time Communication

Concept guides written for developers. Understand WebRTC, WebSockets, signaling, and the architecture choices behind real-time apps — then build with openbnet.

  • What Is a Signaling Server?. A signaling server is the coordination layer that lets two WebRTC peers find each other, exchange connection offers, and negotiate a direct media stream. Here is how it works. Read →
  • WebRTC vs WebSockets: What Is the Difference?. WebRTC and WebSockets are both real-time technologies, but they solve different problems. WebRTC is for peer-to-peer media; WebSockets are for client-server messaging. Here is the difference. Read →
  • What Is Real-Time Communication (RTC)?. Real-time communication (RTC) is technology that lets people exchange information with minimal delay — voice, video, chat, and streaming. Here is what RTC means and how it works. Read →
  • WebRTC Explained: A Developer's Guide. WebRTC is a free, open-source project that gives browsers real-time peer-to-peer audio, video, and data. Here is how WebRTC works, explained for developers. Read →
  • WebRTC Topologies: Mesh vs SFU vs MCU. Mesh, SFU, and MCU are the three WebRTC topologies for group calls. Each has trade-offs in latency, scaling, and cost. Here is how to choose. Read →
  • What Is a Chat API?. A Chat API is a set of protocols and SDKs that let you add real-time messaging to an app without building the infrastructure yourself. Here is how chat APIs work. Read →
  • What Is a Live Streaming API?. A live streaming API lets you add real-time video broadcasting to your app. Here is how live streaming APIs work and what to look for. Read →
  • Scaling WebSocket Connections: A Practical Guide. How to scale WebSocket connections from hundreds to hundreds of thousands. Covers Redis pub/sub, horizontal scaling, connection management, and performance. Read →
