WebTransport is basically the Swiss Army knife of real-time web comms, running natively over HTTP/2 and HTTP/3. It kills the old WebSocket and gRPC headaches by letting you open multiplexed, bidirectional streams—both reliable and “best-effort” unreliable—on a single TLS-secured connection. That means super low latency, simultaneous data flows, and smoother client↔server chatter without wrangling separate channels or hacks.
Because it piggybacks on proven HTTP2/3 foundations, WebTransport slides right into your existing infra and finally gives you a unified, future-proof way to build chat apps, live games, streaming, IoT feeds—and pretty much anything that needs fast, secure, two-way pipes.
