Sandboxing AI agents, 100x faster

What this post added

Introduced the Dynamic Worker Loader API, now in open beta for paid Workers users. This API allows a Cloudflare Worker to instantiate a new Worker dynamically with code specified at runtime, providing a lightweight sandbox for AI agents. This leverages the existing isolate-based sandboxing mechanism of Cloudflare Workers, offering significantly faster startup times and lower memory usage compared to containers. The post also details how to define tools for agents using TypeScript interfaces and discusses HTTP filtering and credential injection capabilities.
