Summary
This handles isolated code execution on Cloudflare Workers with support for Python, JavaScript, and TypeScript. You get sandboxed environments that persist state, file systems, and can expose ports for preview URLs. The runCode() method is built for LLM-generated code with rich outputs, while exec() gives you direct shell access for build pipelines. It runs on Durable Objects with lazy container startup and automatic sleep after inactivity. The Dockerfile extends a base image with Python 3.11 and Node 20, though you'll need Docker locally and a custom domain for production preview URLs. Good fit for AI code interpreters, CI/CD systems, or anything executing untrusted code.
