What will replace WebSockets?

WebTransport is a new specification that could offer an alternative to WebSockets. For applications that need low-latency, event-driven communication between endpoints, WebSockets has been the go-to choice, but WebTransport may change that.

Once this is done, NGINX deals with this as a WebSocket connection.

What is better than WebSockets?

Server-Sent Events is a good alternative to WebSockets for simple realtime use cases that only require one-way communication (from server to client). Examples include read-only realtime apps like stock tickers, or news updates.

Are WebSockets blocked by Firewall?

WebSocket connections generally work even if a proxy or firewall is in place. This is because they use ports 80 and 443 which are also used by HTTP connections. In some situations WebSocket connections are blocked over port 80. In this case a secure SSL connection using WSS over port 443 should successfully connect.

Is WebSocket faster than rest?
