WebTransport ditches the limitations of WebSockets and gRPC by providing multiplexed, bidirectional streams over HTTP/2 and HTTP/3, complete with both reliable and unreliable data channels under TLS. It’s perfect for low-latency, real-time apps—think games, live video, or any interactive service that needs instantaneous, secure communication.
Built on your existing HTTP stack with an extended CONNECT upgrade, WebTransport taps into HTTP/3’s QUIC or HTTP/2’s proven foundation, fixes the woes of HTTP/2 push, and finally lets servers push back without hacks. It’s the next-gen web transport protocol you’ve been waiting for.
