Agents Go Live: Cloudflare Expands Frameworks

Alex Mercer 25.06.2026

Building Robust Agent Frameworks

Cloudflare is opening up its Agents SDK to various agent frameworks, starting with Flue, as the technology matures for production. The move is part of a broader trend where agent harnesses are being deployed as load-bearing infrastructure. This shift is happening as the software controlling a model's access to the outside world has matured.

The Agents SDK is now a runtime that any agent framework can build on, allowing for more flexibility and compatibility. This development is crucial as building production-ready agents is challenging due to the need for them to be robust and reliable. Teams are now deploying agents as real infrastructure, not just prototypes, indicating a significant step forward in the technology.

For agents to survive in production, they must be able to withstand various loads and conditions. The maturation of agent harnesses has been key to this progress, enabling teams to deploy more sophisticated models. By opening up the Agents SDK, Cloudflare is facilitating the development of more robust and compatible agent frameworks.

Can Agent Harness Maturity Keep Pace with Demand?

As agent technology continues to advance, the demand for robust and reliable agent harnesses will only increase. Cloudflare's move to expand its Agents SDK is a response to this growing need. The company's decision to start with Flue indicates a strategic approach to supporting various frameworks.

The expansion of agent frameworks and harnesses to production environments is expected to have significant consequences for the industry. As more teams deploy agents as load-bearing infrastructure, the technology is likely to become increasingly integral to various applications.
