Cloudflare Dynamic Workers: Isolate-Based Sandboxing for AI Agents, 100x Faster Than Containers
Cloudflare·medium signal
Cloudflare launched Dynamic Workers in open beta — a new sandboxing primitive where one Worker can spin up another Worker at runtime with AI-generated code, execute it in an isolate, and discard it immediately. Starts in milliseconds with a few MB of memory, roughly 100x faster startup and 10-100x more memory efficient than Linux containers. Available to all paid Workers users. Directly addresses the agent sandbox security problem at infrastructure level.
