WebTransport is a modern web transport layer that sits on top of HTTP/2 and HTTP/3, letting you multiplex reliable and unreliable data streams over a single, TLS-encrypted connection. It solves key WebSockets and gRPC shortcomings—like the lack of true bidirectional push and datagram support—by offering low-latency, real-time communications straight out of the box.
Because it builds on existing HTTP/2/3 infrastructure, WebTransport is easy to adopt and upgrade, supports server-initiated streams, and plays nicely with proxies. Whether you’re building live gaming, media streaming, or any ultra-responsive web app, it’s poised to become the go-to protocol for next-gen backend communication.
