Cloudflare Flue adopts Durable Streams

While WebSockets and Server-Sent Events have long dominated real-time web application architectures, their lack of built-in connection resiliency and offset-tracking makes them fragile for modern AI agent workloads where state and context preservation are critical. Decoupling stream persistence from client-server state and designing a protocol-first HTTP solution makes real-time applications and agent loops robust against flaky connections.

* **Resiliency for AI Workloads:** Moving to an offset-based resumable protocol is a game changer for long-running, container-based AI workflows, ensuring progress isn't lost mid-operation.

* **Platform Independence:** Being HTTP-based and MIT-licensed ensures that Durable Streams can be cached by CDNs and run across various environments like Cloudflare Workers, Node.js, and CI/CD without specialized broker infrastructure.

* **Validation of Local-First Primitives:** Cloudflare's adoption of Durable Streams for Flue validates the industry shift toward local-first sync protocols and stateful serverless architectures.
