Cloudflare Sandbox SDK
Skill Verified ActiveBuild sandboxed applications for secure code execution. Load when building AI code execution, code interpreters, CI/CD systems, interactive dev environments, or executing untrusted code. Covers Sandbox SDK lifecycle, commands, files, code interpreter, and preview URLs. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.
To enable developers to build secure, sandboxed applications and code execution environments on Cloudflare Workers, facilitating AI code interpretation, CI/CD systems, and development environments.
Features
- Secure code execution in isolated environments
- Support for multiple languages (Python, JS, TS)
- File system operations (read, write, mkdir, list)
- Command execution via `exec`
- Preview URL generation for exposed services
Use Cases
- Executing untrusted AI-generated code
- Building custom code interpreters
- Setting up CI/CD pipelines for secure testing
- Creating interactive development environments
Non-Goals
- Executing code outside of the isolated sandbox environment
- Replacing a full-fledged CI/CD system
- Managing user authentication or authorization within the sandbox
Prerequisites
- Cloudflare account and `wrangler.jsonc` configuration
- Docker installed and running for local development
- Node.js runtime for the agent environment
