WebTransport is a Game Changer Protocol

WebTransport rides on HTTP/2 and HTTP/3 to bring you multiplexed streams—both reliable and unreliable—wrapped in TLS for rock-solid security. It overcomes WebSocket and gRPC limitations by letting you mix ultra-fast, fire-and-forget messages with guaranteed delivery packets, making it perfect for gaming, live streaming, and any low-latency real-time app.

You can start using WebTransport over HTTP/2 today (with reliable streams) and jump to HTTP/3 for the full feature set, including unreliable streams. The video also covers how to upgrade from HTTP, why HTTP/2 push fell flat, issues with YouTube’s notification model, and best practices for proxying WebTransport traffic.
