TL;DR

WebTransport is the next-gen, multipurpose protocol riding on HTTP/2 and HTTP/3 to bring truly bidirectional, low-latency streams to the web. Say goodbye to WebSocket and gRPC headaches—this unified solution handles reliable and fire-and-forget (unreliable) data flows over a single TLS-secured connection, plus it uses the Extended CONNECT method to smooth over upgrades and proxy traversal.

In the video, Hussein Nasser walks through why classic WebSockets, HTTP/2 Push, and gRPC fall short, then dives into how WebTransport fixes those gaps (including why it can’t run “unreliable” over plain HTTP/1.1), how you actually upgrade your requests, and what proxying looks like in real-world backend architectures.
