WebTransport is the shiny new protocol that finally marries HTTP/2 and HTTP/3’s battle-tested plumbing with true multiplexed, bidirectional streams. Imagine ditching WebSockets’ one-track tunnel and gRPC’s browser gymnastics—WebTransport lets you juggle reliable and unreliable data flows, all encrypted with TLS, for super-low-latency, real-time apps like games, live feeds or collaborative tools.
Behind the curtain it rides on an extended CONNECT handshake (no HTTP/1.1 support, sorry), revives what went awry with HTTP/2 Push and flaky notifications, and leans on the ubiquity of modern browsers. In short, it’s the game-changer we’ve been waiting for to bring transport-level flexibility straight to the web.
