WebSocket Alternatives
ELI5 — The Vibe Check
WebSockets aren't the only way to do real-time. Server-Sent Events for one-way streaming. Long Polling for simple compatibility. WebTransport for next-gen speed. Sometimes HTTP/2 streaming is enough. Pick the right tool — not every nail needs the WebSocket hammer.
Real Talk
WebSocket alternatives for real-time communication include: Server-Sent Events (SSE) for server-to-client streaming over HTTP, Long Polling for broad compatibility, WebTransport for multiplexed bidirectional over HTTP/3, HTTP/2 streaming, and gRPC streaming. Choice depends on directionality, browser support, and infrastructure constraints.
When You'll Hear This
"SSE is simpler than WebSockets when you only need server-to-client updates." / "We switched from WebSocket to SSE for our notification feed — one-way is all we needed."

Long Polling Pattern
Long Polling is polling's smarter cousin. Instead of asking 'any updates?
Server-Sent Events Pattern
Server-Sent Events (SSE) is a one-way stream from server to browser over plain HTTP. The server pushes updates, the client just listens.
WebSocket
WebSocket is like upgrading a walkie-talkie from push-to-talk to a full phone call.
WebTransport
WebTransport is the next-gen alternative to WebSockets, built on HTTP/3 and QUIC.
