WebTransport is a next-gen protocol riding on HTTP/2 and HTTP/3 that brings secure, multiplexed bidirectional streams—both reliable and unreliable—to the web. Forget WebSockets’ NAT headaches or gRPC’s rigid request/response model: WebTransport delivers low-latency, TLS-encrypted communication with the flexibility to mix real-time updates and guaranteed delivery over a single connection.
By piggybacking on familiar HTTP layers and extending the CONNECT method, it slots right into your existing infrastructure (no funky proxies needed). Whether you’re building live gaming, VoIP, telemetry dashboards or any app craving instant back-and-forth, WebTransport finally gives you the power and performance to make it happen.
