Building a real-time web or mobile application is a bit more challenging than building a standard service. That’s because the protocol you choose to deliver data from the server to the client — and back — will have a significant impact on the overall experience. By Kieran Kilbride-Singh.
When you need data to flow from the server to the client quickly, a persistent connection is necessary. You do this by using long polling, WebSockets, Server-Sent Events (SSE) or HTTP2 Push.

Today, we’re going to take a look at MQTT and SSE, specifically, to see how they compare:
- A brief history of MQTT and SSE
- How are they different?
- An overview of MQTT in action
- MQTT: Pros and cons
- An overview of SSE in action
- SSE: Pros and cons
The most important thing to consider when comparing MQTT and SSE is their connection capabilities. SSE, for example, is mono-directional and specifically designed for services or applications that need to pull information from a server. MQTT, on the other hand, is a robust, bi-directional communication option that can facilitate data transfers back and forth between the server and client(s). Excellent information here!
