Forget WebSockets’ hacky workarounds—WebTransport brings multiplexed, TLS-secured, bidirectional streams (both reliable and “fire-and-forget”) under one roof over HTTP/2 and HTTP/3. It smooths out gRPC’s browser quirks, slashes latency for real-time apps, and even lets servers push data without waiting for a client request.
Sure, you won’t get unreliable streams on HTTP/2 or any HTTP/1.1 fallback, but with Extended-Connect upgrades and smart proxying, you’re covered. In short, WebTransport lays the plumbing for truly interactive, lightning-fast web experiences.
