If you are building a UI that needs to show progress, logs, or live updates, you do not need to jump straight to WebSockets. In many cases, SSE is the simpler and more appropriate choice.It is a browser-friendly way for the server to push events to the client over HTTP.

SSE is a great option when you need server → client streaming and want to keep the implementation simple.
