Cloudflare Workers and Containers now support inbound TCP connections and gRPC

Cloudflare Blog · August 3, 2026

For developers, founders, and operators across Zimbabwe, Cloudflare’s new support for inbound TCP connections and gRPC within Workers unlocks a significant avenue for building more robust, real-time, and efficient distributed applications. This development means that Cloudflare Workers, a serverless execution environment, can now directly handle raw network traffic and efficiently communicate with other services using gRPC, enabling advanced functionalities previously reserved for traditional server infrastructure. The article details how this integration allows for direct socket forwarding to Durable Objects and Containers, making it possible to create highly interactive and persistent applications. This advancement primarily affects how developers can design and implement backend services, shifting from simpler HTTP request-response models to more sophisticated, persistent, and streaming interactions. For instance, a small e-commerce shop in Harare looking to offer real-time inventory updates or customer service chat can now build these features directly into their Workers, maintaining persistent connections for immediate data exchange without relying on costly dedicated servers. Similarly, a logistics startup based in Bulawayo could use gRPC with Workers to establish real-time tracking of delivery vehicles, pushing updates instantaneously to a central dashboard or mobile applications. This capability allows for more responsive and scalable solutions, reducing latency and infrastructure overhead for businesses of all sizes. Consider a freelance developer in Mutare creating custom software solutions for local businesses. They could now build a secure, real-time data synchronization service for a clinic, ensuring patient records are instantly updated across multiple devices using gRPC streams via Workers. For an internal IT team at a mid-sized mining company near Kadoma, this means they can deploy internal applications requiring continuous data flow, such as machinery telemetry or production monitoring systems, leveraging the global network of Cloudflare for low-latency access and high availability, without managing complex networking infrastructure themselves. The ability to run full-duplex gRPC applications or leverage automatic gRPC-to-gRPC-web translation directly within Workers greatly simplifies the development and deployment of these kinds of applications. To capitalize on this, try setting up a basic Cloudflare Worker that accepts inbound TCP connections. Experiment with creating a simple chat application or a data stream that pushes updates to a client, using a Durable Object to maintain state. This will provide a practical understanding of how persistent connections and real-time data flow can be managed directly within the serverless environment.
