WebTransport is the new game-changer for web comms, stitching together multiplexed, bidirectional streams over HTTP/2 and HTTP/3 with built-in TLS security. It breaks past WebSockets’ single-stream limits and gRPC’s overhead by letting you juggle reliable and unreliable data channels on one connection—perfect for real-time apps that need low latency and high throughput.
By living on top of HTTP/2 and HTTP/3, WebTransport leans on battle-tested infrastructure while resurrecting use cases that HTTP/2 Push killed. It also flips the client-initiated stream model on its head, letting servers ping clients efficiently. In short, it’s the Swiss Army knife of next-gen web transport.
