WebTransport is the shiny new protocol that lets you open up multiplexed, bidirectional streams (both reliable and “fire-and-forget” unreliable ones) over HTTP/2 and HTTP/3. Say goodbye to WebSocket headaches and gRPC constraints—WebTransport gives you low-latency, TLS-secured pipes perfect for anything from real-time gaming to video conferencing, all over a single connection.
It hooks right into existing HTTP/2 and HTTP/3 deployments via an extended CONNECT method (no love for HTTP/1.1) and even plays nicely with proxies. In short, it’s the next evolution of web transport, packed with flexibility and performance for modern backend engineers.
