Cloudflare Workers and Containers Add Inbound TCP and gRPC Support
irvinebroque · x · 2026-08-03
Cloudflare announced that Workers and Containers now support inbound TCP connections and gRPC, addressing the need for low-latency communication in real-time AI assistants and voice interfaces.
Key updates include:
- connect(socket) handler: Allows Workers to directly accept inbound TCP sockets provided by Spectrum (Cloudflare's ingress proxy for non-HTTP traffic).
- Bi-directional gRPC: Supports forwarding sockets from Cloudflare Containers to a gRPC server running inside the container.
- Native gRPC on Workers: Developers can write code using gRPC-web, and Cloudflare automatically converts incoming and outgoing requests to gRPC.
These features are currently in private beta.
