Sandboxing AI agents, 100x faster

Cloudflare introduced Dynamic Worker Loader, an open beta feature for Workers that spins up sandboxed isolates from runtime-generated code.

The design limits environment access and can optionally block outbound network calls, giving AI-agent code a tighter execution sandbox.

Cloudflare says the isolate-based approach reuses its Workers architecture and is about 100x faster and far less memory-intensive than typical containers.

The move could make secure code execution for consumer-facing AI agents cheaper and easier to scale.
