Choosing Between WebSockets SSE and g

Short summary

Most teams default to WebSockets for any real-time requirement, but SSE is dramatically simpler for server-to-client streaming and gRPC streaming is better for typed service-to-service communication. The article provides clear selection criteria: use WebSockets only when the client genuinely sends data back in real time, SSE for browser-bound unidirectional streams, and gRPC for backend contracts.

• •WebSockets are overkill for most server-to-client streaming use cases
• •SSE is simpler handles reconnection automatically and works through standard HTTP/2 infrastructure
• •gRPC streaming is best for typed service-to-service communication with strict schemas
