WebTransport leverages HTTP/3 and QUIC over UDP to address key WebSocket limitations: head-of-line blocking, slow connection setup (multiple RTTs), and broken connections during network switches. It supports both reliable streams and unreliable datagrams, enables transparent connection migration (e.g., Wi-Fi to cellular), and can establish connections in 1 RTT or even 0-RTT for returning users. Community reaction is mixed — many see WebTransport as a specialized tool rather than a drop-in WebSocket replacement, and its HTTPS-only requirement limits local use cases. ## Full article daily.dev links to this article rather than hosting it.
