Cloudflare announced inbound TCP support for Workers through a new connect(socket) handler. Spectrum, Cloudflare’s ingress proxy for non-HTTP traffic, provides the inbound socket to the Worker. Cloudflare Containers can forward a full-duplex, bidirectional gRPC socket to a gRPC server running in a container. Workers can also expose unary and server-streaming gRPC APIs and call gRPC servers. The announcement targets low-latency workloads such as real-time assistants, AI dictation, and voice interfaces.
