What is Cloudflare Dynamic Worker Loader?

It's an API to spin up V8 isolate sandboxes on-demand in Workers, perfect for running AI-generated JS code securely.

How much faster is it than containers for AI agents?

100x faster startup (ms vs. hundreds ms), 10-100x less memory — ideal for per-request agent tasks.

Yes, via WASM/Python, but JS is fastest for quick agent snippets. Word count: ~1050.

Containers are choking AI agents with slowness. Cloudflare's Dynamic Worker Loader flips the script using battle-tested V8 isolates.
