Cloudflare Workers has broken its long-standing HTTP-only limitation by adding native inbound TCP support, with gRPC becoming the first protocol built upon this capability. Leveraging Spectrum for traffic proxying and Durable Objects for processing, the feature enables bidirectional persistent connections that significantly reduce latency in voice AI scenarios. Currently in private testing, future updates are planned to extend support to UDP protocols.

    • Workers evolved from HTTP-only servers to accepting raw inbound sockets via a connect handler, allowing direct read/write or forwarding to Durable Objects.
    • gRPC is the first beneficiary protocol, leveraging underlying TCP persistent connections to optimize latency-sensitive scenarios like voice AI.
    • Spectrum acts as a unified ingress proxy for non-HTTP traffic, routing TCP flows into the Worker runtime environment.
