About

Cloudflare Sandboxes run untrusted or agent-written code apart from your application. Containers run an image you provide as a microVM with its own kernel, and Dynamic Workers run JavaScript, Python or WebAssembly code loaded at runtime. Both are reached through a Worker, which decides which APIs and data the code receives and whether it can reach the internet.

Use cases: cloud-management, containers-kubernetes
