Developers running AI-generated code who need fast, isolated sandboxes; it needs the Workers Paid plan, with per-day charges after 1,000 workers.

Kenning's take

What it does

Dynamic Workers let developers spin up Cloudflare Workers at runtime to run code that is supplied on the fly, such as code written by an AI agent. They use lightweight isolates instead of containers, which Cloudflare says start about 100 times faster. Developers control which bindings each sandbox gets and whether it can reach the network.

• Run arbitrary code in isolated sandboxes at runtime
• Isolate-based, with millisecond start times
• Control over bindings and network egress
• Built for agent "Code Mode" and AI-generated apps
• Observability and custom resource limits

Who it suits. Developers building AI agents or platforms that need to run untrusted code safely.
