SSE supports one-way communication from the server to the client, while WebSockets support bidirectional communication. SSE uses HTTP, while WebSockets use their own custom protocol. SSE is simpler to set up and manage, but WebSockets allow for more flexibility with message structure and support binary data. Both have their own security considerations. The performance of both technologies depends on the underlying client implementation. Overall, SSE and WebSockets have their own strengths and use cases. ## Full article daily.dev links to this article rather than hosting it.
