WebTransport is a next-gen protocol that layers on HTTP/2 and HTTP/3 to deliver multiplexed, secure, bidirectional streams—both reliable and “best-effort”—in a single connection. It tackles WebSocket, HTTP/2 Push and gRPC pain points by offering ultra-low latency, client-and-server-initiated streams wrapped in TLS, making it perfect for real-time apps like gaming, live notifications and collaborative tools.
Because it rides on HTTP’s proven foundation, you can piggyback on existing infrastructure while enjoying extended CONNECT semantics, proxy support and seamless upgrade paths. In short, WebTransport merges the best of web and transport tech into one streamlined, future-ready package.
