WebSockets vs Server-Sent Events vs WebRTC in 2025
Choose the right real-time communication protocol. Compare WebSockets, SSE, and WebRTC for live data streaming and chat applications.
Real-Time Communication
WebSockets power 67% of real-time apps with 50-100ms latency. SSE offers simpler setup with automatic reconnection. WebRTC provides ultra-low latency (<50ms) for peer-to-peer.
Technology Comparison
| Tech | Direction | Latency | Use Case |
|---|---|---|---|
| WebSockets | Bidirectional | 50-100ms | Chat, gaming |
| SSE | Server→Client | 100-200ms | Feeds, notifications |
| WebRTC | Peer-to-Peer | <50ms | Video calls |
