Differences Between Server Sent Events and WebSocket Connections Differences Between Server Sent Events (SSE) and WebSockets Understanding the differences between Server Sent Events (SSE) and WebSockets is crucial for developers when deciding how to implement real-time web functionalities. Below is a simple guide that outlines the main differences between these two technologies.
