WebTransport TL;DR

WebTransport is the shiny new way to do real-time, bidirectional web comms on top of HTTP/2 and HTTP/3. It tackles WebSocket and gRPC pain points by offering multiplexed streams—both reliable and “best-effort” unreliable—packed into a single TLS-secured connection for ultra-low latency.

In short, it leverages everything we love about HTTP/2/3 (think headers, flow control, proven deployments) while fixing old quirks like client-only streams and dead-in-the-water server pushes. If you’re building anything from live gaming to real-time analytics, you’ll want to give WebTransport a spin.
