Cloudflare Launches Dynamic Workers Open Beta: Isolate-Based Sandboxing for AI Agent Code Execution (opens in new tab)

Cloudflare has released Dynamic Worker Loader into open beta, offering V8 isolate-based sandboxing for AI-generated code execution. The company claims isolates start in milliseconds, using megabytes of memory, making them roughly 100x faster and up to 100x more memory-efficient than containers. The feature builds on Cloudflare's Code Mode approach.
