WebTransport is the next-gen web protocol that finally fixes long-standing real-time comms woes: it gives you multiplexed, bidirectional streams (both reliable and “fire-and-forget” unreliable) over HTTP/2 and HTTP/3, all wrapped in TLS. That means you get low-latency, client-and-server-initiated data flows without the headaches of WebSockets, gRPC workarounds, or dead-end HTTP/2 push.
In the video, Hussein walks through why legacy approaches fall short, how WebTransport handles upgrades and proxying, and why having unreliable streams is a game changer for backfill, notifications, and ultra-fast interactions. The talk wraps up with tips on extending CONNECT, proxy setups, and why YouTube’s notification struggles might’ve been avoided with this protocol.
